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.

This paper shows the feasibility of SQL/MDR development. Previous approach has several problems such as complicated exchanging mechanism, dependent description to local MDR systems, high cost for adding new systems, etc. Until now, the advantages of SQL/MDR have been qualitatively shown in several papers. In this paper, its merits are illustrated in quantitative views. Especially, we focus on the query modeling cost. To do this, we define several factors and evaluation model. Through the quantitative evaluation, the reason why SQL/MDR is required for exchanging metadata can be explicitly identified.
