The Data Access Server (DAS) process (iigcd) is a component of the General Communications Architecture (GCA) and runs as part of a standard Ingres instance.

The server translates JDBC or .NET Data Provider requests from the JDBC Driver or the .NET Data Provider into Ingres or Vector internal format and forwards the request to the appropriate DBMS server. The DAS supports the same network protocols and port designations as the Communications Server.

Through the DAS, a JDBC or .NET Data Provider client has full access to Ingres, Vector, Enterprise Access, and EDBC databases. Using Net, the DAS can also provide JDBC or .NET Data Provider clients with access to these databases on remote machines.
