One-year-old Active Software Inc is to update its software – which extends existing applications and data to the web – with a toolkit to enable developers to build their own adapters. The adapters would allow users to integrate data written in languages such as C, Cobol and SmallTalk into their web systems. ActiveWeb Developer Suite 1.2 will ship in December. Yesterday, the 20-person, Mountain View, California firm added Microsoft Windows NT and SQL Server database support. The pro duct already provides adapters for Informix, Oracle and Sybase servers. The NT version was delayed because bugs were found during beta testing and took 45 days to fix, Active said. The product initially shipped in July.
