Atlanta-based Dun & Bradstreet Software says it will soon announce a payroll and personnel package with relational capabilities, a development tool that enables customers to build distributed or co-operative applications and three additional financial applications for DEC VAX computers, and says that it is currently spending more than a third of its development resources on this area; it also plans to develop an architecture or development framework that will encompass open systems, including IBM’s Systems Application Architecture (open?) and Unix, and this effort is taking a quarter of its research and development budget.
