SQL Server Data Access Components (SDAC) is a library of components that provides native connectivity to SQL Server from Delphi and C++Builder including Community Edition, as well as Lazarus (and Free Pascal) for Windows, Linux, macOS, iOS, and Android for both 32-bit and 64-bit 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.

InterBase (and FireBird) Data Access Components (IBDAC) is a library of components that provides native connectivity to InterBase, Firebird and Yaffil from Delphi, C++Builder, Lazarus (and Free Pascal) on Windows, Mac OS X, iOS, Android, Linux, and FreeBSD for both 32-bit and 64-bit platforms. IBDAC-based applications connect to the server directly using the InterBase client. IBDAC is designed to help programmers develop faster and cleaner InterBase database applications. IBDAC is a complete replacement for standard InterBase connectivity solutions. It presents an efficient alternative to InterBase Express Components, the Borland Database Engine (BDE), and the standard dbExpress driver for access to InterBase.

FaceSDK enables Microsoft Visual C++, C#, Objective C, Swift, Java, VB and Delphi developers to build 32-bit and 64-bit applications for Web, Windows, Linux, macOS, iOS and Android with face recognition and face-based biometric identification functionality.
