...SqlClientDAC-based applications connect to SQL Server directly through the ADO.Net SqlClient, which is a .NET Framework Data Provider for SQL Server. SqlClientDAC is designed to help programmers develop faster and cleaner SQL Server database applications. SqlClientDAC uses its own protocol to communicate with SQL Server. SqlClientDAC is lightweight and performs well because it is optimized to access a SQL Server directly without adding an OLE DB or Open Database Connectivity (ODBC) layer. SqlClientDAC, a high-performance and feature-rich SQL Server connectivity solution, is a complete replacement for standard SQL Server connectivity solutions and presents an efficient native alternative to the Borland Database Engine (BDE) and standard dbExpress driver for access to SQL Server.
