Universal Data Access Components (UniDAC) is a powerful library of nonvisual cross-database data access components for Delphi, Delphi for .NET, C++Builder, and Free Pascal. The UniDAC library is designed to help programmers develop faster and cleaner cross-database applications. UniDAC is a complete replacement for standard database connectivity solutions and presents an efficient native alternative to the Borland Database Engine and dbExpress for access to Oracle, SQL Server, MySQL, InterBase, Firebird, SQLite, DB2, Microsoft Access, Advantage Database Server, Adaptive Server Enterprise, and other databases (using ODBC provider). UniDAC is based on the well-known Data Access Components from Devart such as ODAC, SDAC, MyDAC, IBDAC, and PgDAC. We have joined the experience of long-term successful development into one great product which provides unified access to popular databases such as Oracle, Microsoft SQL Server, MySQL, InterBase, Firebird, SQLite, DB2, Microsoft Access, Advantage Database Server, Adaptive Server Enterprise, and other databases (using ODBC provider). The UniDAC library is actively developed and supported by Devart Team. If you have questions about UniDAC, email the developers at unidac@devart.com or visit UniDAC online at http://www.devart.com/unidac/. Advantages of UniDAC Technology UniDAC is very convenient in setup and usage. It provides transparent server-independent interface for working with different databases. Selected database provider ensures the best way to perform operations on the server. Universal Data Access UniDAC provides transparent server-independent interfaces for working with different databases, and lets you change the client engine for specific server type just by changing single connection option. It means that you can easily switch between database servers in your cross-database UniDAC-based application. Server-Aware Providers UniDAC chooses the best way specific to the server to perform most operations. Every UniDAC data provider uses server-specific native connectivity. All operations with data are performed by providers automatically considering peculiarities of the selected database server. Optimized Code The goal of UniDAC is to enable developers to write efficient and flexible database applications. The UniDAC library is implemented using advanced data access algorithms and optimization techniques. Classes and components undergo comprehensive performance tests and are designed to help you write high-performance, lightweight data access layers. Compatibility with Other Connectivity Methods The UniDAC interface retains compatibility with standard VCL data access components like BDE. Existing BDE-based applications can be easily migrated to UniDAC and enhanced to take advantage of server-specific features. Development and Support UniDAC is a cross-database connectivity solution that has been actively developed and supported. UniDAC comes with full documentation, demo projects, and fast (usually within one business day) technical support by the UniDAC development team.
