New York-based Information Builders Inc has announced Focus for Wang VS Image Gateway, designed to enable companies to incorporate existing data and applications on IBM 370 and AS/400 systems with Wang Laboratories Inc imaging systems on the VS, eliminating the downstream costs of application integration, additional resources and end-user re-training: document images are stored and maintained on the Wang VS Image Server and the Focus product links the document image to data and applications on the mainframe and AS/400 to create a screen level data exchange with the hosts; Image Gateway maintains and accesses a Focus database on the VS that indexes specific mainframe and AS/400 data to document images, whereupon a second Focus database on the VS maps this information to specific 3270 application screens; prices go from $1,658 for a VS 5000 Model 30 to $18,090 for a VS 10000.
