a large-scale, distributed parallel information server supporting extended relational database technology for the commercial marketplace
EDS is targeted at the main business sectors of the industrial partners. These sectors need large-scale information servers supporting (extended) Relational Database (RDB) technology. EDS can be introduced into customer installations as an accelerator to give an order of magnitude improvement in the cost/performance ratio of existing applications. The development of the database extensions and the support of Lisp and Prolog will give EDS the capability of extending the functionality of applications.
A large-scale distributed store parallel processing system including an RDB subsystem, Lisp and Prolog language subsystems and a UNIX microkernel operating system has been implemented. The porting of applications, representing the target market, is also included, giving a strong integration focus to the project.
The EDS technologies and components have been developed over the last 4 years. The final year, covered by the follow-on EDS II project (6057), is mainly devoted to system integration.
In practice, the EDS project has involved the design and implementation of a parallel hardware machine and a parallel machine executive, EMEX, to support the EDS parallel database base management system (DBMS). Moreover, a number of AI programming language sub-systems -parallel LISP and ElipSys, parallel logic programming system -have been developed within EDS.
ICL has launched its Goldrush MegaServer open systems database server based on the results of this project; Bull plans to use the database technology in future database products; and SNI intends to introduce new parallel hardware into its data-processing product lines.
