Abstract

SQL/MDR is a metadata registry query language used to consistently exchange and share the data between distributed metadata registries. It is an extension of the international SQL and is familiar to most database builders and administrators. It provides many advantages such as simplicity of query language, ease of use, an independent description for distributed querying, low cost for adding new systems, simplicity of exchanging mechanism, and so on. The goal of this paper is to evaluate and show its merits quantitatively. To achieve this goal, we define simulation models to compare with an existing approach and then describe the evaluation results. In the quantitative evaluation results, the good points of SQL/MDR can be identified and known.
