Following the trend spearheaded by Unify Corp with its Accell 4GL tool set a few years ago, Ingres Corp is expected to make the first moves in liberating its own tool sets from the Ingres database next month. Ingres Windows 4GL, well received as a graphical, object-oriented development tool, but with a surprisingly low profile for a two-year-old product, is expected to make a two-stage move towards supporting multiple databases, with announcements about a middleware product expected next month. Third party companies such as Boca Raton, Florida-based TechGnosis Inc, with its SequeLink SQL middleware product, have taken a similar approach. The Ask Computer Systems Inc company hopes to be early with SQL92, the specifications for which should finally be settled next month, and is also working with Microsoft Corp and the SQL Access Group on Open Database Connectivity compliance. Compliance with X/Open Co’s XA transaction processing architecture is also promised for next year.
