Oracle Data Access Components (ODAC) is a library of components that provides native connectivity to Oracle from Delphi, Delphi for .NET, C++Builder and Kylix. 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.
