Strategies for Forecasting Emergency Department Demand
Strategies for Forecasting Emergency Department Demand A Multivariate Time Series Approach to Modeling and Forecasting Demand in the Emergency Department Introduction: Reports by the General Accounting Office, American College of Emergency Physicians, and the Institute of Medicine (IOM) depict an overburdened United States crisis care framework described by congestion and patient consideration delays. From 1993 to 2003 crisis division (ED) visits expanded by 26% while the quantity of EDs diminished by 9%. These shifts in supply and interest have made a situation in which numerous EDs consistently work at or past their composed limit. A 2002 study charged by the American Hospital Association found that roughly 66% of every last one of EDs overviewed accept that they are working at or above limit. The same study found that the impression of congestion is absolutely related with the intricacy of administrations the doctors facility offers and is more predominant among clinics in urban settings. Notwithstanding having an antagonistic effect on patient and clinician fulfillment, ED congestion has malicious impacts on the both the quality and timetables of consideration conveyed in the ED. Expanding interest consolidated with developing lack of ED administrations makes the productive allotment of ED assets progressively imperative. In their report, the IOM prescribes that clinics use data innovation and utilization operations research techniques to end up more productive [3]. Interest anticipating is one such technique, determining is a broadly pertinent, multi-disciplinary science, and is a fundamental movement that is utilized to guide choice making in numerous zones of financial, mechanical, and experimental arranging. Demonstrating and anticipating interest is a dynamic territory of request among crisis medication scientists. Models and strategies that may be valuable for giving choice backing continuously for operational and asset portion errands have been quite compelling. A mixture of distinctive techniques have been proposed as suitable method for gauging request in the ED, a percentage of the proposed routines are: uni-variate time arrangement demonstrating, r ecreation displaying, queuing hypothesis, and machine learning strategies. The last goal was to investigate the potential utility of our multivariate determining models to give choice backing continuously for available to come back to work attendant staffing. The capacity to powerfully conform and assign staffing assets is prone to develop in significance as regulations obliging doctors facilities and EDs to hold fast to medical caretaker staffing proportions get to be more normal. The most settled samples of such government regulations exist in the condition of California where healing facilities have been obliged to watch particular patient-to-medical caretaker proportions subsequent to 2004. These regulations are questionable; in any case, government regulation of patient-to-attendant staffing proportions in different parts of the nation is plausible and pertinent enactment is being proposed on both the state and Federal levels. In spite of the fact that medical attendant staffing proportions remain politically dubious, the logical proof is convincing th at these proportions have a critical effect on nature of consideration, and a powerful group of writing has amassed showing that decreases in the patient-to-attendant proportion are connected with huge diminishments in mortality, unfavorable occasions, and patient length of sit tight. Methods: Study design: This was a review study utilizing totaled information for the year 2006 that was extricated from ED data frameworks. The neighborhood institutional survey board sanction this study and waived the necessity for educated assent. Study setting: This study was led utilizing information gathered from three healing centers worked by Inter-mountain Healthcare, a not-for-profit incorporated conveyance arrange that works clinics and facilities in Utah and southern Idaho. The three clinics were picked in light of the fact that they change in size and setting and the way in which the ED interfaces with whatever is left of the clinic. Table beneath gives unmistakable measurements to every clinic, and extra significant office attributes take after.

Data collection and processing: Information for this investigation were extricated from Intermountain Healthcares Oracle based electronic information distribution center. Accumulated hourly information were separated by means of SQL questions. Measures of statistics were gathered for every hour. ED patient evaluation was spoken to as the tally of patients either sitting tight for or getting treatment in the ED. Inpatient enumeration was characterized as the quantity of patients possessing an inpatient bed. Interest for research facility assets was measured as the quantity of lab batteries (e.g., complete blood check) that were gathered amid a given hour (e.g., 12:00:00–12:59:59). Preparatory examination showed that 26 basic lab batteries (Appendix A) represented pretty nearly 80% of the research facility volumes at the EDs included in this investigation. With a specific end goal to better study the effect of inpatient request on ED request we verified that it would be most fitting to cutoff our examination t o a center arrangement of research facility tests for which a noteworthy increment popular inside or remotely could have harmful impacts on ED operations. Thusly, just this center arrangement of 26 research facility batteries was incorporated in our numbers of ED and inpatient lab volumes. Comparative basis drove us to center our investigation on the interest for radiography and CT, as these two modalities represented right around 90% of the interest for radiology administrations at the EDs examined. We gathered the quantity of radiography and CT examining requests for every hour from the ED and inpatient healing center. Extra variables gathered incorporate hourly numbers of patient entries. All variables gathered and included in our investigation are abridged in Table underneath. Table 2Time series variables collected for analysis and inclusion in multivariate forecasting models Variable Definition ED arrivals Count of patients arriving to the ED during a given hour ED census Count of patients waiting for or receiving service in the ED on the hour ED laboratory orders Count of laboratory batteries ordered in the ED during a given hour ED radiography orders Count of radiography orders made in the ED during a given hour ED computed tomography (CT) orders Count of CT orders made in the ED during a given hour Inpatient census Count of patients occupying an inpatient bed on the hour Inpatient laboratory orders Count of laboratory batteries ordered in the inpatient hospital during a given hour Inpatient radiography orders Count of radiography orders made in the inpatient hospital during a given hour Inpatient CT orders Count of CT orders made in the inpatient hospital during a given hour Outcome measures Out-of-sample forecast accuracy was assessed for forecast horizons ranging from one to 24à ¢Ã¢â€š ¬Ã¢â‚¬ ¦h in advance by calculating the mean absolute error (MAE). The MAE is a frequently used and intuitive measure of forecast accuracy that measures the magnitude of the deviation between the predicted and observed values of a given time series. For a series of predicted valuesand the corresponding series of observed values (y1,y2,†¦,yn) (1) Model validation and forecasting Our essential target was to assess the legitimacy of our models as far as their capacity to give precise post-test conjectures of registration and of the interest for indicative assets in the ED. This was finished through a reproduced post-test estimating situation in which we incrementally extended the preparation set by 1à ¢Ã¢â€š ¬Ã¢â‚¬ ¦h and afterward produced figures for every single endogenous variable for skylines going from one to 24à ¢Ã¢â€š ¬Ã¢â‚¬ ¦h ahead. This methodology empowered us to create one to 24à ¢Ã¢â€š ¬Ã¢â‚¬ ¦h ahead figures for every one of the 840à ¢Ã¢â€š ¬Ã¢â‚¬ ¦h in the acceptance set. We assessed the estimate precision of our models by registering the MAE for every figure skyline (1–24à ¢Ã¢â€š ¬Ã¢â‚¬ ¦h). We analyzed the gauge exactness attained to utilizing the VAR models to a benchmark uni-variate guaging technique. The benchmark strategy picked was occasional Holt-Winters exponential smoothing. Exponential smoothing is a standout amongst the most common determining strategies and in light of its prosperity and incessant utilization we felt that it gave a reasonable benchmark. The last goal was to investigate the potential utility of our multivariate determining models to give choice backing continuously for operational and asset designation undertakings. To do this we assessed the oppressive force of the yield from our gauging models in anticipating cases when satisfactory patient-to-medical attendant proportions would be surpassed. We utilized the four to one ED patient to ED attendant proportion that is commanded by the condition of California as our reference standard of an adequate patient-to-medical caretaker proportion. We characterized any occurrence where the watched ED registration surpassed the normal ED statistics by four or more patients (i.e., the ED is understaffed by a full attendant) as a case of under-staffing. We confirmed that in these cases it would be valuable to have propelled cautioning that would empower an extra RN to be reached preceding the adequate patient-to-attendant proportion being surpassed. Keeping in mind the end goal to do this we entered the figure deviation from the normal ED enumeration (conjecture ED censusà ¢Ã¢â€š ¬Ã¢â‚¬ ¦Ã¢Ë†â€™Ãƒ ¢Ã¢â€š ¬Ã¢â‚¬ ¦ED expected registration) for figures made 1–12à ¢Ã¢â€š ¬Ã¢â‚¬ ¦h ahead of time into a solitary variable logistic relapse model. The biased force of the single variable logistic relapse models taking into account the gauged deviation to anticipate occurrences of under-staffing was surveyed through the observational figuring of the full region under the collector working trademark bend (AROC) for every estimate skyline. Every measurable analysis including the determining model improvement and assessment were performed utilizing the R factual program. Table 3p-Values for bivariate Granger-causality tests conducted using the data from Hospital 1, column labels indicate which variable is being evaluated as a leading indicator (regressor), and row labels indicate which variable is being evaluated as the dependent variable Dependent variable Regressor ED Census ED labs ED radiography ED CT Inpatient census Inpatient labs Inpatient radiography Inpatient CT ED census NA 0.11 0.95 0.94 0.93 0.90 ED laboratories NA 0.39 0.24 0.21 0.09 0.23 0.59 ED radiography NA 0.54 0.71 0.37 0.25 0.02 ED CT NA 0.97 0.89 0.45 0.63 Inpatient census 0.98 0.88 0.16 0.24 NA 0.08 0.68 Inpatient laboratory 0.91 0.54 0.96 0.66 NA Inpatient radiography 0.74 0.98 0.51 0.74 NA Inpatient CT 0.35 0.11 0.25 0.07 NA Table 4Goodness-of-fit statistics (MultipleR2) for each endogenous variable included in the eighth order vector autoregression model for Hospital 1 Endogenous variable MultipleR2 ED census 0.97 ED laboratory volumes 0.80 ED CT volumes 0.50 ED radiography volumes 0.70 Inpatient census 0.99 Inpatient laboratory volumes 0.91 Inpatient CT volumes 0.71 Inpatient radiography volumes 0.88 Forecasting results Since our graphic investigations showed that almost no prescient worth was liable to be picked up by including variables speaking to inpatient request in estimating models for interest in the ED, we chose to fit two VAR models for every Hospital. VAR demonstrate 1, or the full model, included both inpatient and ED variables, while VAR display 2 included just ED variables. Both VAR models included ED understanding entries as an exogenous variable. Every model was equipped for creating conjectures just for the endogenous variables included in the model; in this manner, VAR display 1 created figures for inpatient and also ED variables, while VAR show 2 produced gauges just for ED variables. Since the accentuation of this study is gauging request in the ED we just report measures of exactness for ED variables. The consequences of our post-test model approval are introduced for every office. For every figure we present measures of the estimate slip (MAE) for conjecture skylines extending from 1 to 24à ¢Ã¢â€š ¬Ã¢â‚¬ ¦h ahead for ED registration, lab, radiography, and CT volumes. Every figure demonstrates the MAE accomplished utilizing VAR models 1 and 2 and the gauge precision utilizing Holt-Winters exponential smoothing. At Hospitals 1 and 2, VAR models 1 and 2 gave more precise estimates of interest for all ED variables for conjecture skylines up to 24à ¢Ã¢â€š ¬Ã¢â‚¬ ¦h ahead when contrasted with the benchmark uni-variate anticipating technique. At Hospital 3, VAR models 1 and 2 gave better or equivalent figure exactness for skylines up to 24à ¢Ã¢â€š ¬Ã¢â‚¬ ¦h for ED patient statistics, and for ED research center and radiography volumes. We distinguished almost no contrast between the estimating execution of the full model, display 1, and the model that just joined ED variables, demonstrate 2. This outcome verifies what we found amid our distinct examinations, i.e., that minimal prescient quality would be gathered by demonstrating the collaboration between inter est in the ED and the inpatient doctors facility. Fig. 11 exhibits four different plots, in the first we see the watched contrasted with the normal ED evaluation (taking into account recorded midpoints) for one week (11/26/2006–12/2/2006) at Hospital 2. This figure demonstrates that in a few examples amid this specific week (e.g., Thursday and Friday evening) there were vast deviations (12 patients or all the more) in the watched ED enumeration from the normal ED statistics. The three remaining plots in Figure present the watched ED registration contrasted with the guage ED statistics at 1, 2, and 3à ¢Ã¢â€š ¬Ã¢â‚¬ ¦h ahead. These plots demonstrate that 1à ¢Ã¢â€š ¬Ã¢â‚¬ ¦h ahead utilizing model 2 we have the capacity to figure ED statistics at a high level of exactness, at 2à ¢Ã¢â€š ¬Ã¢â‚¬ ¦h ahead our expectations are less precise yet ready to foresee critical takeoffs from typical ED evaluation levels, and at 3à ¢Ã¢â€š ¬Ã¢â‚¬ ¦h ahead our forecasts start to relapse towar ds the normal ED registration. Fig. 12 presents watched, expected, and anticipated research center volumes in the same route as in Fig. 11 for that week. Pretty much just like the case with ED statistics, Fig. 12 display critical variety even in the wake of representing hourly and week after week cycles. On the other hand, dissimilar to ED evaluation our model does not seem to do almost also at foreseeing compelling flights from expected standards even at short. Conclusion: VAR models gave understanding into the elements of interest in the ED and the inpatient healing facility at our neighborhood destinations, and gave more exact gauges of ED statistics for stretched out conjecture skylines when contrasted with standard univariate time arrangement techniques. http://home.ubalt.edu/ntsbarsh/stat-data/topics.htm http://www.j-biomed-inform.com/article/S1532-0464(08)00063-4/fulltext

Akc Dog Breeds Essay -- essays research papers
We humans classify everything that we have come to know in this world, from elements to all God’s creatures. Man likes to know he has control and the classification and selective processes man takes are all for control. Even mans’ best friend has been narrowed down into groups which man created. In each group are dogs that have been breed for a specific use to help man do a job faster, easier, and more efficiently. â€Å"Every breed is assigned to one of seven groups, based on the uses for which the breeds were originally developed†(AKC.org). Mans’ best friend has been categorized into the: Hound, Working, Terrier, Toy, Non-Sporting, Herding, and Sporting Groups.      The Hound Group contains such popular dogs as the Basset Hound, Bloodhound, and Greyhound. There are 22 separate breeds in the Hound Group alone. This group can be further separated into the scent hounds and the sight hounds. Scent hounds have been bred to find their prey by their overdeveloped sense of smell. Sight hounds were bred to spot targets at great distances and let their handlers know where the prey is located.      The Working Groups is a group of 21 different breeds of dogs. These dogs â€Å"were bred to perform such jobs as guarding property, pulling sleds, and performing water rescues†(AKC.org). Some common breeds in this group are the Great Dane, Doberman Pinscher, and Boxer. These dogs were bred for specific tasks but all needed to be intelligent, quick at learning, and good companions.

PHP vs. ASP Scripting Software Research Paper Essay
ABSTRACT This paper examines the differences between the ASP (Active Server Pages) and PHP (Hypertext Preprocessor) scripting languages. Both ASP and PHP are scripting languages that can be used to create dynamic web pages which are capable of interacting and exchanging information with databases. ASP is a Microsoft product, and is used with Internet Information Server (IIS) which runs on Microsoft Servers. PHP was originally designed by Rasmus Lerdorf, and was later modified by various people. As a parsing language, PHP can run both on Unix and Linux servers, and also has a version that runs on an NT server. This paper also discusses the differences in cost, speed, integration of features, speed, additional costs, base language, database connectivity and Platform Compatibility between both languages. This paper also presents some suggestions offer recommendations as to when one of these languages should be preferred over the other, and how efficiency can be maximized in the usage of each of these scripting languages Introduction             ASP and PHP are both website design scripting languages that are processed by backend severs like Apache Server and Windows OS. Apache Server is usually used for PHP and a Windows OS with IIS Server is used to process ASP scripted websites. PHP processed website scripts can also be processed by UNIX OS backend servers, while Window OS IIS backend servers are used to process ASP scripts. ASP.NET is part of the .NET Framework and is the core technology for developing web applications and XML Web Services. ASP.NET is a compiled, .NET-based environment; you can author applications in any .NET compatible language, including Visual Basic .NET, C#, and JScript .NET. Additionally, the entire .NET Framework is available to any ASP.NET application. Developers can easily access the benefits of these technologies, which include the managed common language runtime environment, type safety, inheritance, and so on. .NET developers write Web Parts using Visual Studio.NET 2003. The Web Part Framework is the basis for extensibility in Windows SharePoint Services. It allows developers to write custom components that plug into the SharePoint infrastructure by encapsulating web services and enterprise data as Web Parts. Web Part Pages are special ASP.NET pages which are the building blocks of a Windows SharePoint Services based data driven web site. Web page authors can use Microsoft FrontPage 2003 to leverage Windows SharePoint Services and use the Web Part Framework to easily build data driven web sites using a library of readily available web parts. Microsoft FrontPage 2003 integrates closely with Windows SharePoint Services and is the easiest and the most powerful web site design tool that enables creation of a new category of collaborative, scalable, data driven web sites. (http://www.sharepointcustomization.com/resources/whitepapers/webpartdocs/wp_asp_net.doc)            PHP and ASP are the two best web technologies in use today. In their own ways, they have created trust and market for their product and development environment, although many people are of the opinion that PHP is an all around better choice than ASP.            According to Anstey, â€Å"PHP belongs to a free software community and open source general purpose software which is very easy to use and correct its bugs from the community of developers around the world.†(Anstey 2003). ASP runs on an IIS server and is a free component with the Microsoft windows operating system. ASP offers various useful features like type safety, inheritance, and a managed common language runtime environment.            In a broad sense, PHP is scripting Language, while ASP.NET is a Designing Tool. Also, PHP contains mainly scripting tabs, with a minimum number of controls being used, while ASP.Net has a lot of controls to the designing process.           ASP.NET is a unified Web development platform that provides services necessary for developers to build enterprise-class Web applications. ASP.NET provides programming model and infrastructure for more secure, scalable, and stable applications. ASP.NET is a compiled, .NET based web environment developed in .NET compatible languages like Visual Basic .NET, C#, JScript.NET, etc. Additionally, the entire .NET Framework is available to any ASP.NET application. Developers can easily access the benefits of this technology, which includes the managed common language runtime environment, type safety, and inheritance.             From many views and perspectives, PHP is an overall better choice than ASP. Although both ASP and PHP are languages used to build Dynamic Web sites that can interact with Databases and exchange information. ASP (Active Server Pages) is from Microsoft and is used with IIS (Internet Information Server) that runs on Microsoft Servers. PHP (PHP: Hypertext Preprocessor) is from Rasmus Lerdorf, who originally designed this parsing language which was later modified by different people. It runs on Unix and Linux servers and it also has an NT server version. (Pires, Halstatt 2005. ASP vs. PHP. Retrieved 18, February 2008 from http://www.webpronews.com/expertarticles/2005/12/22/asp-vs-php)            The foundation of all Web applications is that they deliver dynamic content over a protocol which by model is stateless. Most of the ASP.NET developments fall in client-server architecture programming model. Minimal points to be considered for a typical web application modeled as client-server architecture are given below. User interface and client environment (Page layout). Data verification, transfer and store. Security. Scalability, reliability and availability of the application. Optimized resource utilization and performance. Handling unpleasant instances gracefully. Navigation.            PHP traces back to the development of Perl and C which emerged quite successfully as a result of the contribution of the various programmers around the globe and as a result of its being an open community. The various versions came out successfully through 1997 to 2004 where the features were added and successfully taken up to cater to the development paradigm of the large scale of internet users.            ASP came handy with Windows 95 with the features of IIS server installed. It was an established standard which takes into account the various databases into consideration and is based on the COM model. The various differences among PHP and ASP make sure that all to a good extent the feature are compiled and carries enough advantage to understand the loopholes and make sure that all the various utilities are enforced well. Differences between PHP and ASP            PHP and ASP depict a large array of differences in the form of various factors. Some differences between ASP and PHP include differences in cost, speed, integration of features, speed, additional costs, base language, database connectivity and Platform Compatibility. Cost             As PHP is not singly owned by any individual or an organization, it does not require purchase before use. â€Å"PHP uses a database technology named MySQL for back-end support. MySQL is also available free of cost.†(DuBois, 2002). The hosting and deployment of PHP webpages into the Linux server is quite affordable and can be done with ease.             â€Å"ASP is synchronized with the Microsoft Windows operating system and comes along with it, thereby bearing the cost of the operating system.†(Glass 2004) Moreover, hosting ASP pages over the internet is expensive and features like email, file uploading and other features are quite expensive at the same time. PHP is free, but ASP is not free. If you want to use ASP, you have to use IIS, and if you want to use IIS, you have to buy Windows. Traditionally, the cost of Windows has been high. Microsoft has been aggressively trying to reduce this factor but they’re hardly going to give Windows away for free. The cost of running an ASP-based website implies a full Windows server platform; development costs are higher, software licenses are expensive and speed, security and flexibility are all sacrificed. (Anstey, M 2003)             To run ASP programs, one needs IIS installed on a Windows platform server, which is not free. PHP programs can run on Linux, which is free. Even the connectivity of the database is expensive in the case of ASP as MS-SQL is a Microsoft product that needs to be purchased. PHP generally uses MySQL, which is freely available.            Many of the tools used in PHP are free of charge and a lot of PHP code can be found in open source forums, because PHP is open source. â€Å"PHP also has inbuilt features like ftp, email from a web page and even encryption mechanisms but such features are not built into ASP, which requires some additional components. Therefore additional costs might be incurred for such components.†(Pires, Halstatt 2005. ASP vs. PHP. Retrieved 18, February 2008 from http://www.webpronews.com/expertarticles/2005/12/22/asp-vs-php) Speed            In terms of speed, PHP is faster than ASP, because when the speed of PHP and ASP are compared, PHP would have the upper hand. â€Å"This is due to the fact that PHP code runs faster than ASP. Also, ASP is built on COM based architecture, which is an overhead for the server, whereas PHP code runs in its own memory space.†(Pires, Halstatt 2005. ASP vs. PHP. Retrieved 18, February 2008 from http://www.webpronews.com/expertarticles/2005/12/22/asp-vs-php) Integration with operating environments and databases             PHP makes sure that all the operating environments are taken care to its fullest capability and is compatible with Windows, UNIX, Linux, Solaris and others. Its platform dependency format makes sure that all the various compatibility with operating environments makes it quite viable in nature. PHP integrates with the databases like MySQL and others in a great fashion. â€Å"ASP on the other hand is compatible with Windows only and makes sure that Microsoft oriented databases like MSSQL server would be well integrated with it. For other database platforms it requires to download various libraries and components for integration and workability.†(Hull, 2002) Performance             PHP is an interpreted language and make sure that the interpreted nature makes it fast for getting the customization done. The memory requirement of the PHP pages is quite optimizable and runs very fast with the greater understanding of the various features. Database connections of PHP are also quite flexible and make sure that all the various database functionality like stability, transactions, replication, triggers and stored procedures are handled quite well (Merrall, 2000).             ASP on the other hand is a compiled language and the software glitches are quite often not corrected or take a long time to get it done. The compiled nature makes sure that all the various factors like throughput and response time is quite low for the hosted pages. Its exclusivity with Microsoft windows operating system makes it platform independent with regard to various hosting and access problems. PHP offers the best integration of speed and performance, and ensures that all the various promises are met for catering to the web development. ASP is most suitable with the Microsoft platform and makes sure that all the features are captured and managed for the various services. (Zhang, 1999). Base Language           ASP has a type of syntax that resembles Visual Basic, and is closely related to Microsoft products. In contrast, PHP is based on the C++ language, and the syntax used for PHP looks a lot like C/C++ programming syntax. â€Å"C/C++ is still considered the best programming language by many programmers and people who love this language would surely feel more comfortable with the syntax of PHP.†(Pires, Halstatt 2005. ASP vs. PHP. Retrieved 18, February 2008 from http://www.webpronews.com/expertarticles/2005/12/22/asp-vs-php) Enhanced capabilities and compatibility               These include file transfer programs and utilities, compression of data, uploading of files, integration of XML an MD5, encryption techniques and email facilities are not included in ASP, even if it does it requires the support of large third party packages installed, which are very easily integrated in PHP. PHP.net (2008) mentions that complex functions like dynamic images, IMAP, SNMP, dynamic flash, PDF, native access to Oracle, Ovrimos, Postgre, Sybase, mSql, MSSQL, Ingres, Interbase and Informix databases, LDAP, and sockets and many others are easily integrated with PHP, â€Å"however it would create a big problem with its integration with ASP. PHP is compatible with various web servers for its functioning however ASP requires it to be easily integrated with only IIS and PWS†as explained by Pires (2005).            PHP programs can run on various platforms like Linux, Unix, Windows and Solaris whereas ASP is mainly associated with Windows platforms. However, ASP can run on a Linux platform with ASP-Apache installed on the server. PHP is based on C++ language and the syntax used in PHP is quite similar to C/C++. C/C++ is still considered the best programming language by many programmers and people who love this language would surely feel more comfortable with the syntax of PHP. ASP on the other hand has a more Visual Basic kind of syntax that again is closely related to only Microsoft products. So, it depends on the individual, and which language he or she is comfortable with.           For Database connectivity, PHP is being extremely flexible, and can connect to various databases, the most popular being MySQL. ASP mainly uses MS-SQL for databases. Conclusion             Although both ASP and PHP are good web server end languages for web development, there are some differences between them that should be considered to ensure that factors like cost, installation, performance, and compatibility issues are economized to the full extent. Both languages have advantages specific to various users. Some would argue that both languages have their own importance, and usage of either ASP or PHP depends on the user’s requirements, the language and the platform in use. â€Å"If a user is looking for some e-commerce application development then ASP is probably the ideal choice. This does not mean that PHP cannot provide e-commerce solutions, but a lot of people tend to choose ASP in such instances.†(Pires, Halstatt 2005). If we talk about developing a discussion board then ASP is equally capable but some people feel that the best discussion boards are developed using PHP.             While PHP offers the best integration of speed and performance, and ensures that most web development requirements are met, ASP is most suitable with the Microsoft platform, and enables features to be captured and managed for various services.

The Renaissance, Renaissance And The Renaissance Period
Renaissance is a time period that starts a transitional cultural movement in Europe between medieval times and modern times. It means rebirth and begins in 14th century and lasts into the 17th century. Through out this time, many aspects were influenced by this cultural movement, such as art, music, science, religion and politics. Renaissance was marked by the humanistic revival, and people in Europe used this method in study, in order to searched for realism and human themselves in art.
