The impact can be measured by the extent to which the EREQ reference architecture has influenced the Query Processing Module of the Open OODB architecture. Query optimizer for Texas Instruments Open OODB. Prof. Goetz Graefe, part of the Revelation group, and his graduate student, Bill McKenna, worked with Jose' Blakeley at TI to build an optimizer for ZQL[C++] using the Volcano optimizer generator. We judge this effort to have positive impact as the optimizer is the one distributed in Open OODB releases. The query optimizer generator is distributed by Graefe, graefe@cs.pdx.edu, (503) 725 5544. Tandem has indicated intent to use Graefe's new optimizer framework in the next development cycle. Collaboration with the Object Data Management Group. ODMG is a consortium of all major object database companies, including Ontos, Versant, O2 Technology, Objectivity, Object Design, Servio and POET. ODMG has published a proposed standard for OODBs called ODMG93, which all member companiers have committed to implement by the middle of CY95. EREQ members acted as reviewers for that standard. Our coming year activities are focused on applying EREQ query processing technology to OQL, the query language of ODMG-93. in Proceedings of the Workshop on Combining Declarative and ObjectOriented Databases, , Washington, D.C., May 1993 view details in Proceedings of the 1996 ACM SIGMOD Conference on Management of Data view details |
