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 both 32-bit and 64-bit Windows platforms. SDAC-based applications connect to SQL Server directly through OLE DB, which is a native SQL Server interface. SDAC is designed to help programmers develop faster and cleaner SQL Server database applications.
