Dear Friends, I am developing an union catalogue of journal holdings of some selected libraries with MYSQL as an RDBMS. In this connection, I would like to know if any one has done similar work using any RDBMS. If so, may I request him/her to please let me know the number of tables used and the structure of each of the tables and primary key used in each of the tables? thanks g.k.manjunath ************************************************** CHIEF LIBRARIAN INDIRA GANDHI INSTITUTE OF DEVELOPMENT RESEARCH FILM CITY ROAD ( GEN.VAIDYA MARG ) SANTOSH NAGAR GOREGAON ( EAST ) MUMBAI - 400 065 INDIA e-mail : gkm@igidr.ac.in http:// www.igidr.ac.in/lib/library.htm phone 22-8490653 ************************************************
