In ASP.Net 2.0, Microsoft Access database connection string can be declared inside the connectionstrings section of web.config file. In ASP.Net 2.0 Microsoft has introduced a new feature of directories for different types of resources. In ASP.Net 2.0 there is a default directory App_Data to store the database files. You can store the MS Access database file inside the App_Data directory that can be useful for providing its relative path in the connection string for Access Database. MS Access database supports the OLEDB drivers to connect with ASP.Net web applications. Here Oledb stands for Object Linking and Embedding Database. ASP.Net consists of a provider class for OLEDB under System.Data.Oledb namespace that allows you to connect the MS Access database with ASP.Net web application.
