Primena virtuelizacije u cilju integracije relacionih i NoSQL baza podataka, na primeru Oracle-a

Abstract

Pojava NoSQL baza podataka otvorila je pitanje njihove koegzistencije sa relacionim sistemima za upravljanje bazom podataka. Nakon početnih nesuglasica oko tumačenja nove paradigme, postalo je evidentno da će u narednom periodu ova dva pristupa u projektovanju struktura baza podataka paralelno postojati. Pitanja koje se u poslednjih nekoliko godina aktuelizovalo je da li je moguće napraviti mehanizam njihove integracije, pri čemu bi svako rešenje zadržalo svoje specifičnosti. Različiti pristupi su primenjivani u pokušaju davanja odgovora. Jedan od njih je i uvođenje sloja virtuelizacije. Ovaj pristup preuzet je iz referentnih radova (testirano na MySql i MongoDB), a u ovom radu je analizirana mogućnost proširenja skupa različitih baza nad kojima je moguće integrisati rešenje, konkretno sa Oracle-om. Pored testiranja mogućnosti integracije izvršeno je testiranje i analiza uticaja primene sloja virtuelizacije na performanse spomenutog sistema.

The emergence of NoSQL databases has opened the question of their coexistence with relational database management systems. After initial misunderstandings about the way new paradigm should be understand, it became evident that in the upcoming years, these two approaches (relational and NoSQL systems) will be used in parallel. in recent years, question whether is it possible to make the mechanism of their integration, in which any solution will retain its specifity became actualized. Different approaches were applied in attempt to give answer to the mentioned question. One of them is the introduction of the virtualization layer. This approach has been taken from reference works (tested on MySQL and MongoDB). This paper analyzes the possibility of expanding the set of database management systems that could be used as a data source for integration between relational and NoSQL systems, on the example of Oracle. Beside testing integration possibilities, impact on performance, after applying virtualization layer, was tested and analized.
