tcACCESS – Mainframe Databases

DB2      IMS DL/I      ADABAS      DATACOM      IDMS

SQL access to IMS/DB and DL/I

The tcACCESS SQL Engine provides a direct access to IMS or DLI-databases from different Open System environments or mainframe-platforms using SQL-syntax. Highlight of the tcACCESS technology is the flexibility and transparency. 
 
tcACCESS supports the join of information from IMS or DLI-tables with information from other, non-relational mainframe data-sources (i.e. VSAM, DB2, ADABAS, CA-Datacom, CA-IDMS, PDS/PS). The end-user can use relational data-views that contain all data relevant to him. tcACCESS is responsible for the fast and efficient data-access.
