Universal Data Access Components

Von devart

Universal Data Access Components (UniDAC) is a library of components that provides direct access to multiple databases from Delphi and C++Builder including Community Edition, as well as Lazarus (and Free Pascal) on Windows, Linux, macOS, iOS, and Android for both 32-bit and 64-bit platforms.

Universal Data Access Components comes in three different editions:

  • The Standard edition includes the UniDAC common engine and data providers.

  • The Professional edition shows off the full power of UniDAC, including mobile application development, data encryption, and additional components for working with databases, such as TUniAlerter, TUniDump, TUniMetaData, TCRBatchMove, etc. Professional Edition also includes the Direct mode for Oracle, SQL Server, MySQL, and PostgreSQL, and static library linking – for SQLite. In addition, UniDAC Professional Edition includes the DataSet Manager tool, which is intended to organize datasets in your application.

  • You can get Source Access to UniDAC Professional Edition by purchasing a special UniDAC Professional Edition with Source Code, which includes the source code of all component classes. The source code of DataSet Manager and Migration Wizard is not distributed. The source code of the Direct mode for Oracle and SQL Server is distributed obfuscated, and for SQLite – as precompiled packages.

Universal Data Access Components (UniDAC) is a powerful library of nonvisual cross-database data access components for Delphi, C++Builder, and Lazarus (Free Pascal). The UniDAC library is designed to help programmers develop faster and cleaner cross-database applications.
