<p>Paralelan i nezavisan rad više projektanata na različitim modulima (podsistemima) nekog informacionog sistema, identifikovanim saglasno početnoj funkcionalnoj dekompoziciji realnog sistema, nužno dovodi do međusobno nekonzistentnih rešenja šema modula baze podataka. Rad se bavi pitanjima identifikacije i razrešavanja problema, vezanih za automatsko otkrivanje kolizija, koje nastaju pri paralelnom projektovanju različitih šema modula i problema vezanih za integraciju šema modula u jedinstvenu šemu baze podataka informacionog sistema.</p><p>Identifikovani su mogući tipovi kolizija šema modula, formulisan je i dokazan potreban i dovoljan uslov stroge i intenzionalne kompatibilnosti šema modula, što je omogućilo da se, u formi algoritama, prikažu postupci za ispitivanje stroge i intenzionalne kompatibilnosti šema modula. Formalizovan je i postupak integracije kompatibilnih šema u jedinstvenu (strogo pokrivajuću) šemu baze podataka. Dat je, takođe, prikaz metodologije primene algoritama za testiranje kompatibilnosti i integraciju šema modula u jedinstvenu šemu baze podataka informacionog sistema.</p> / <p>Parallel and independent work of a number of designers on different information system modules (i.e. subsystems), identified by the initial real system functional decomposition, necessarily leads to mutually inconsistent database (db) module schemas. The thesis considers the problems concerning automatic detection of collisions, that can appear during the simultaneous design of different db module schemas, and integration of db module schemas into the unique information system db schema.</p><p>All possible types of db module schema collisions have been identified. Necessary and sufficient condition of strong and intensional db module schema compatibility has been formu-lated and proved. It has enabled to formalize the process of db module schema strong and intensional compatibility checking and to construct the appropriate algorithms. The integration process of the unique (strong covering) db schema, on the basis of compatible db module schemas, is formalized, as well. The methodology of applying the algorithms for compatibility checking and unique db schema integration is also presented.</p>
