Universal Data Access Components 2.0

Universal Data Access Components 2.0 is an impressive and unique library of nonvisual cross-database data access components for Delphi, Delphi for .NET, C++Builder, and FreePascal. It  has combined the experience of long-term successful development into one product, which provides unified access to the popular database servers like Oracle, Microsoft SQL Server, MySQL, InterBase, Firebird, PostgreSQL, and SQLite.

UniDAC offers unified approach to the database-related applications development process. That means 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. UniDAC gives outstanding flexibility and independence to your projects.
