Acu4GL supports the following RDBMSs:
|RDBMS||Latest Versions Tested||Probable compatibility, based on vendor information
(Client/Server may be used for connecting to other versions)

The essence of Acu4GL is that standard COBOL I/O statements are used to access databases. Acu4GL handles the translation between standard COBOL and the language that the RDBMS understands.
Specific instructions and status messages apply to each type of RDBMS, and these are included in their own RDBMS-specific sections.
