DatabaseClient

From SP extreme:

DatabaseClient is a set of objects for use with the .NET framework, which provides a wrapper for all the standard database calls. DatabaseClient currently supports SQL Server, Oracle, OLE and ODBC calls.

DatabaseClient includes two objects. They are called DatabaseWrapper and DatabaseHelper.

DatabaseWrapper is used to create a database connection and make SQL calls to the database using either a Query or Non-Query based call. The wrapper also supports Scalar calls. DatabaseWrapper was designed so that all the database calls incur no more overhead then directly interacting with the standard database provider methods.
DatabaseHelper is used to make it even easier to interact with your database. It contains a set of static methods to quickly obtain the data you require from your database. The set of methods provide all of the same database interactions as DatabaseWrapper.

The DatabaseClient is completely document using the MSDN format to make it easier to read and find information.

With DatabaseClient you will no longer need to write complicated database calls for different database provides. You�ll wonder how you lived without it.
