The rivalry between BEA Systems and IBM has intensified as each trumpets tighter business-integration features in new software products.
Both companies last week unveiled updated middleware systems designed to help enterprises link their dated and disparate systems with the Web.
BEA fired the first salvo in the battle last Monday at its annual technology conference in Florida, launching version 8.1 of its flagship WebLogic product.
WebLogic is an application server suite that directly competes against IBM's WebSphere platform.
The market for this kind of middleware - software that glues together separate and often already existing programs in a computing system - is predicted to be worth US$4.4 billion by 2006, according to research firm International Data Corp.
BEA chairman and chief executive Alfred Chuang said the new and improved WebLogic combined custom applications development and integration into a single, 'industrial-strength' software platform.
