HELP THE NEXT-GENERATION - A NEW CLIENT-SERVER ARCHITECTURE

A new client-server based system which is centered around a lifetime d ata repository (LDR) is under construction. The goal of the new system is to maintain the patient centered decision support aspects of the e xisting HELP system while providing an open architecture that support s faster application development and allows execution of applications to be distributed across many computers. These goals are achieved by i mplementing the system with software components that are commercially available or by adhering to national and international standards for s oftware integration. Keys to successful integration include the use of MS-DOS@, OS/2#, and UNIX Section as operating systems, Microsoft OLE 2.0 as a standard interface to the clinical database, the use of TUXED O as a transaction/communication manager, and the use of ORACLE(paragr aph) RDBMS as the underlying database management system.
