Base class for all database abstracters. It implements the following functions:

• SQL request parser - using the standard parameter format (see the format description)
• SQL request execution - using either a SqlStatement or a plain text SQL request
• Transaction management - by default, each SQL request is executed against a new connection from the pool; once BeginTransaction is called, all request will be launched on the same connection, inside a transaction, until either Commit or Rollback is called
• Parameter creation helper - the various CreateAndAddParameter(IDbCommand, DbType, String, Object) methods create a parameter according to the provider and add it to the provided IDbCommande

When you derive from this class, you must implement the following members:

• ExplainException (ExplainException(DbException, String, String)) - SQL exceptions are completely provider dependent in ADO.NET
• OpenConnection (OpenConnection) - You only have to create the connection object from the provider (for example SqlConnection)
• CreateSqlStatement (CreateSqlStatement) - You must create a class derived from SqlStatement (SqlStatement) and use it here

Base class to create a IDatabaseAbstracterFactory.

Defines a class providing a generic access to a SQL database.

The factory interface for IDatabaseAbstracter. Implementing classes must inherit from ConfigurationSection in order to be declared in the application's configuration file.
