Abstract

U radu se proučavaju najčešće korišteni obrasci i postojeća programska rješenja za upravljanje istodobnim pristupom podacima u relacijskim bazama podataka u Web okruženju. Protokol vremenskih oznaka uspoređuje se s dvofaznim protokolom zaključavanja i ocijenjenjuje se prikladnost tih protokola za korištenje u Web okruženju. U radu je opisana implementacija programskog sustava koji omogućava obavljanje transakcija koje sadrže temeljne (CRUD) operacije nad n-torkama relacijske baze podataka pozivima REST servisa, pri čemu je upravljanje istodobnim pristupom podacima osigurano protokolom vremenskih oznaka. Razvijeni sustav je testiran i u radu su prikazani rezultati testova.

Abstract (english)

This paper examines the most frequently used forms and existing software solutions for managing concurrent access to data in relational databases in the Web environment. Timestamp protocol is compared with two-phase locking protocol. This paper estimates the suitability of these protocols for use in the Web environment. The paper describes the implementation of software system that allows transactions which contain basic (CRUD) operations on records in the relational database. The implemented software system is REST service with a secured concurrency control access to data using a timestamp protocol. The developed system has been tested and the paper presents the results of tests.
