| Abstract: |
SIMBAD is an astronomical database which gathers very heterogeneous information about astronomical objects, which makes it particularly suitable for Object Oriented Database Management Systems. And, as a matter of fact, the SIMBAD software was already build in-house around object oriented concepts more than 10 years ago. It is therefore tempting now to develop a prototype of SIMBAD using available commercial ODMBS. Two prototypes were built independently with Objectivity/DB and O2 (ArdentSoftware), allowing us to explore these two database systems and compare their functionalities and performances. The paper presents the results of this work. It shows through a few examples how the database design has to fit with the functionalities provided by each system. Queries using the current SIMBAD and the two prototypes are compared. More generally, the type of application suitable for each database system is discussed. |
