Ingres Corp yesterday launches Ingres/Windows 4GL, a visual programming tool and applications development system claimed to accelerate creation of applications on workstations dramatically. The company claims it is the first development system to combine the benefits of an object-oriented fourth generation language with a graphical user-interface management system for workstations. The Alameda, California company says that developers can build and modify database applications by choosing objects with a mouse and arranging them on the screen and can create forms and complex menus without any programming. Versions for the Sun Microsystems Sparc machines and DEC VAX/VMS arrive in the third quarter at $1,000 per node with two to eight nodes. Versions are planned for Hewlett-Packard HP-UX, DEC Ultrix and Santa Cruz Operation Open Desktop.
