Omnis Data Access Modules

Omnis Data Access Modules (DAMs) plug-in to Omnis, enabling native and multi-tier connection to proprietary
Database Management Systems (DBMS).

To connect to proprietary databases (other than Omnis datafiles, SQLite datafiles, MySQL and PostgreSQL) you need the Professional edition of Omnis Studio. Depending on the database vendor you may also need to install the appropriate third-party clientware on each machine that will be connecting to the database server. Two-tier DAMs use this clientware to complete the connection to the remote database server.

The following tables list the database connections available with Omnis Studio. Where a DAM is listed as being supported, please refer to the appropriate clientware configuration/certification matrix for further information on the third-party clientware required.

Where a DAM is not supported on a given platform, this is usually because the appropriate clientware is not available or is unstable or incompatible with our existing code base, preventing the code from being ported at the current time.

  • DAMOMSQL connects using the V3 DAM API but is single-threaded only.
  • Type 4 JDBC drivers are embedded and require no additional software. Lower version drivers may required additional clientware.
  • Open Client 15.0 is required to connect to ASE 15.0
  • DAMPGSQL is not compatible with Omnis Studio 4.1 and earlier.
  • Please note that single-threaded (V2) DAMs are not available in the unicode version of Omnis Studio.
  • Worker support indicates support for SQL worker/multi-tasking objects, new in Studio 6.0.
