<p>Doktorska disertacija pripada oblasti<br />informacionih sistema, odnosno podoblasti koja<br />se bavi upravljanjem skladištenjem i<br />pretraživanjem informacija. Osnovni cilj<br />disertacije je modeliranje i implementacija<br />skupa alata koji omogućavaju upotrebu fazi<br />logike u radu sa relacionim bazama podataka.<br />Da bi se do tog skupa alata došlo, najpre je<br />relacioni model podataka proširen elementima<br />teorije fazi skupova, a zatim je definisano fazi<br />proširenje upitnog jezika SQL – PFSQL.<br />Interpreter za taj jezik je implementiran u<br />okviru fazi JDBC drajvera koji, osim<br />implementacije interpretera, sadrži i elemente<br />koji omogućavaju jednostavnu upotrebu ovih<br />mehanizama iz programskog jezika Java. Skup<br />alata je zaokružen implementacijom CASE<br />alata za razvoj fazi-relacionog modela baze<br />podataka. Osim toga, razmatrane su i<br />mogućnosti za upotrebu PFSQL jezika u<br />višeslojnim aplikacijama.</p> / <p>This doctoral dissertation belongs to the<br />field of information systems, subfield<br />information storage and retrieval management.<br />The main subject of the dissertation is modeling<br />and implementation of a set of tools that allow<br />usage of fuzzy logic in relational database<br />applications<br />In order to achieve that goal, at first, the<br />relational data model is extended with elements<br />of fuzzy set theory. After that, a fuzzy<br />extension of the SQL query language, called<br />PFSQL, is defined. An interpreter for that<br />language is implemented as a part of the fuzzy<br />JDBC driver. Beside the implementation of the<br />interpreter, this fuzzy JDBC driver contains<br />elements that allow simple usage of offered<br />mechanisms from Java programming language.<br />The set of tools is concluded with the<br />implementation of the CASE tool for the<br />development of fuzzy-relational data models. In<br />addition, possibilities to use PFSQL language<br />on the middle tier of multi tier systems are<br />discussed.</p>
