tcACCESS – Mainframe Files

SQL access to VSAM

The tcACCESS SQL Engine provides a direct access to VSAM-files 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 VSAM-files with information from other, non-relational mainframe data-sources (i.e. IMS, DLI, 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.
