UniDAC Standard Edition includes the UniDAC common engine, but does not include server-specific data providers. Required providers can be installed with ODAC, SDAC, MyDAC, IBDAC. UniDAC Standard Edition is a cost-effective solution for those database application developers who need only several of supported data providers, or already have some of DACs.

UniDAC Professional Edition includs all UniDAC Standard Edition features with support for four data access providers: Oracle, SQL Server, MySQL, InterBase/Firebird/Yaffil. In addition, UniDAC Professional Edition includes the DataSet Manager tool which is intended to organize datasets in your application.

Unified SQL support - Unified SQL allows to write truly database-independent SQL code. Unified SQL includes:

Macros - in Unified SQL macros can evaluate to a different value depending on the provider used by the TUniConnection component.

If - for the purpose of extra flexibility Unified SQL supports conditional inclusion of SQL code into resulting statements. This allows to set different SQL for different DBMS.

Functions - standard for calling common SQL functions. In run time function is transformed either to the corresponding native function, or to an equivalent expression.

Literal - provides universal syntax for date, time, and timestamp literals.

TUniLoader component - serves for fast loading of data to the database. For each type of database server TUniLoader uses its specific interfaces for loading with maximum speed. For example, Oracle Direct Path Load interface is used for Oracle.

TUniDump component - serves to store data from tables or editable views as a script and to restore data from a received script.

TUniConnection.AssignConnect method - shares physical connection between several TUniConnection components
