The purpose of thesis is to benchmark the database to examine and analyze the performance using the Microsoft COM+ the most commonly used component framework heavily used for developing component based applications. The prototype application based on Microsoft Visual C#.NET language used to benchmark the database performance on Microsoft .NET Framework environment 2.0 and 3.0 using the different sizes of data range from low (100 Rows) to high volume (10000 Rows) of data with five or ten number of users connections. There are different type of application used like COM+, Non-COM+ and .NET based application to show their performance on the different volume of data with specified numbers of user on the .NET Framework 2.0 and 3.0.
The result has been analyzed and collected using the performance counter variables of an operating system and used Microsoft .NET class libraries which help in collecting system’s level performance information as well. This can be beneficial to developers, stakeholders and management to decide the right technology to be used in conjunction with a database. The results and experiments conducted in this project results in the substantial gain in the performance, scalability and availability of component based application using the Microsoft COM+ features like object pooling, application pooling, role- based, transactions isolation and constructor enabled.
The outcome of this project is that Microsoft COM+ component based application provides optimized database performance results using the SQL Server. There is a performance gain of at least 10% in the COM+ based application as compared to the Non COM+ based application. COM+ services features come at the performance penalty. It has been noticed that there is a performance difference between the COM+ based application and the application based on role based security, constructor enable and transaction isolation of around 15%, 20% and 35% respectively. The COM+ based application provides performance gain of around 15% and 45% on the low and medium volume of data on a .NET Framework 2.0 in comparison to 3.0. There is a significant gain in the COM+ Server based application on .NET Framework 3.0 of around 10% using high volume of data. This depicts that high volume of data application works better with Framework 3.0 as compared to 2.0 on SQL Server.
The application performance type results represents that COM+ component based application provides better performance results over Non-COM+ and .NET based application. The difference between the performance of COM+ application based on low and medium volume of data was around 20% and 30%. .NET based application performs better on the high volume of data results in performance gain of around 10%.
Similarly more over the same results provided on the test conducted on the MS Access. Where COM+ based application running under .NET Framework 2.0 performs better result other than the Non-COM+ and .NET based application on a low and medium volume of data and .NET Framework 3.0 based COM+ application performs better results on high volume of data.
