Kratak sadržaj – U radu je dat uvid u osnovnu problematiku podešavanja performansi i optimizacije upita nad bazom podataka. Objašnjene su osnovne vrste indeksnih struktura koje se mogu koristiti u procesu optimizacije upita. Dat je prikaz sistema za upravljanje bazama podataka i detaljnije objašnjeni relacioni SUBP korišćeni u ovom radu. Specificirani su slučajevi upotrebe na osnovu kojih je izvršeno testiranje performansi u tri različita SUBP-a. Na kraju, prokomentarisani su i upoređeni dobijeni rezultati. Ključne reči: Baza podataka, optimizacija, indeksi, performanse. Abstract – In this paper we give an insight into the basic issues of tuning performance and query optimization within a database. The basic types of index structures that can be used in the query optimization process are explained. The database management systems and the relational DBMSs used in this paper are presented. Use cases were specified to perform performance testing in three different DBMSs. Finally, the results obtained are shown and compared.
