Silicon Strip Detector (SSD) for STAR experiment will be composed of more than 7000 componentes coming from different manufacturers. Almost all of them are thoroughly tested by manufacturers and/or at different laboratories. Also assembly process is distributed over diverse locations. All information coming from tests, measurements as well as concerning objects flow must be stored in reliable repository. To assure data integrity and easy access to data for experts in order to make possible quality control we developed system based on MySQL DBMS and contemporary software technologies such as WWW, PHP, JAVA etc. SQL queries are invisible for users. On the flight graphical data presentation is based on GD library and ROOT. Special software tools for adding assembly process (choice of appropriate components) have been developed. Networking is also important feature of our system. Measurement data are transferred directly from LabVIEW based application to database. Replication of database takes place between servers located in Strasbourg and Warsaw. General conclusions concerning detector production databases design for High Energy Physics experiments are presented too.
