Comparative Study of Web Application Development with SQL Server and Db4o

This thesis work is a comparative study of technical features between three distinctivemethods for database access. A web store which offers software components to download,for registered users has been built with three different database access methods to drawcomparisons. 1. SQL Server 2005 with stored procedures 2. LINQ to SQL 3. Db4o Working in Visual Studio with three different methods for database access was not difficult.SQL Server with Stored procedures is efficient in performance and offers maintainability ofthe database access logic. LINQ to SQL makes queries to database as first-class languageconstruct providing type-safety and Intellisense. LINQ to SQL has relatively lowperformance compared to Stored procedures because of the translation of LINQ queries toSQL Queries to communicate with the database. Db4o solves the problem of impedancemismatch and making the development of Database model much simpler and similar to theapplication domain model. Although Db4o has its own drawbacks with database size andconcurrency. Db4o can be considered as an alternative to Relational Database ManagementSystems. Db4o works particularly well with applications which have a small data footprint
