Powerful library of VCL/VCL.NET/CLX cross-database data access components

Universal Data Access Components (UniDAC) is a powerful library of nonvisual cross-database data access components for Delphi, Delphi for .NET, and C++Builder. We combined experience of long-term successful development into one great product, which provides unified access to popular databases such as Oracle, Microsoft SQL Server, MySQL, InserBase, and Firebird.UniDAC offers unified approach to the process of development of database-related applications. That means that you can switch easily between different databases in your projects without going deep into their specifics.Using UniDAC with its server-independent interface is the best way to create cross-database applications. Thanks to UniDAC your prokects will be flexible and independent.UniDAC supports the following IDEs: CodeGear RAD Studio 2007, C++Builder 2007, 2007 for Win32, Turbo Delphi Professional, Turbo Delphi for .NET Professional, Turbo C++ Professional, Borland Developer Studio 2006 including support of Delphi for Win32, Delphi for .NET and C++Builder personalities, Borland Delphi 5/6/7/8 and 25, Borland C++Builder 5/6.
