dotConnect Universal is based on ADO.NET technology and can be used in the same way as the SQL Server .NET Data Provider. The main feature of dotConnect Universal is an access to multiple database servers at the same code. With dotConnect Universal it is possible to avoid writing conditional code for different providers or using ADO.NET interfaces directly. dotConnect Universal implements full support of design-time development and integration with IDE, which allows to reduce development time greatly.
dotConnect Universal doesn't implement database specific access layer for all databases, it uses native ADO.NET providers and depends on their functionality. The Professional Edition of dotConnect Universal includes bundled data providers for Oracle, MySQL and PostgreSQL (see diagram below). For all other servers you need a native data provider.
