SQL Server Data Access Components (SDAC) is a library of components that provides native connectivity to SQL Server from Delphi, C++Builder, Lazarus (and Free Pascal) for Windows (both 32-bit and 64-bit) and Mac OS X. SDAC-based applications connect to SQL Server directly through OLE DB, which is a native SQL Server interface. SDAC, 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.
