tcACCESS is a powerful integration platform (Mainframe Software, Workstation software, Middleware) for users of IBM mainframes. tcACCESS allows a transparent integration of mainframe data sources and mainframe programs into Open System applications using industry standards like SQL, ODBC, JDBC, .NET.  tcACCESS is a modular software solution. It consists of a base system that can either be implemented as a CICS transaction or as a VTAM application. The base system provides its own communication modules. The heart of the system is the tcACCESS SQL Engine which allows access to mainframe data sources using SQL statements. tcACCESS offers Listener components on the mainframe and on the client, as well as scheduling and security functions. Batch processors automate the information exchange processes between distributed applications.
