UniDAC

Editions

Universal Data Access Components comes in three editions: Express, Standard, and Professional.

The Express edition is free. It includes the UniDAC common engine, but does not include any data providers and additional components. UniDAC Express Edition supports only the following data providers: Oracle, SQL Server, MySQL, InterBase (Firebird), PostgreSQL, and SQLite, which are installed with ODAC, SDAC, MyDAC, IBDAC, PgDAC, and LiteDAC, respectively.

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.

The matrix below compares features of UniDAC editions. See Features for the detailed list of UniDAC features.
