York-based Thomson Computers Ltd has enhanced its Sea-Change fourth generation application development system by providing a multiple file access facility which will enable users to access more than one type of database, and combine data from these separate sources into one report. Multi-Database Sea-Change, which comes hard on the heels of its new generation of Sea-Change accounting systems launched in June of this year, works with industry standard file systems such as C-ISAM, Informix and Ingres as well as Thomson’s own X-ISAM. Managing director Neil Thomson says the system has been developed as a direct response to the problems users face when running a variety of operating systems requiring different relational databases on different machines. It presents a single interface to the user who is able to develop local applications and use data from existing applications held on one or more relational databases. The product will be made available in several stages, initially providing an ability to develop applications in Sea-Change which will integrate with either Ingres or Informix databases. New applications are planned, including French and German language versions. The Multi-Database Sea Change Applications Generator costs UKP2,200 on the ICL Clan 4. Multi-database facilities were apparently an important requirement for ICL, which has now signed a joint marketing agreement with Thomson, for worldwide marketing rights to Sea-Change on its Clan and DRS Unix-based machines. ICL will market the product via its direct sales force.
