Oracle Data Access Components (ODAC) is a library of components that provides native connectivity to Oracle from Delphi, Delphi for .NET, C Builder, Kylix, and Lazarus (Free Pascal). The ODAC library is designed to help programmers develop faster and cleaner Oracle database applications.
ODAC is a complete replacement for standard Oracle connectivity solutions and presents an efficient native alternative to the Borland Database Engine and dbExpress for access to Oracle.
ODAC is a direct connectivity database wrapper built specifically for the Oracle server. ODAC offers wide coverage of the Oracle feature set, supports both Client and Direct connection modes, and emphasizes optimized data access strategies.
