Analiza in implementacija predpomnenja v samostojni Java aplikaciji : diplomsko delo

Sešek, Kristjan (author), Bajec, Marko (mentor)

V delu obravnavamo problem predpomnenja trajnih objektov v javanski aplikaciji v okolju Java Enterprise Edition. Najprej spoznamo teorijo predpomnenja in v programskem jeziku Java implementiramo preprost predpomnilnik. V nadaljevanju bolj podrobno spoznamo ogrodje Java Enteprise Edition. Osredotočimo se predvsem na tehnologije za prenos podatkov med javansko aplikacijo in strežnikom in med strežnikom in podatkovno bazo, saj neposredno vplivajo na problem predpomnenja. Na praktičnem primeru prikažemo, kako lahko ob spreminjanju povezanih trajnih objektov predpomnilnik postane nekonsistenten. Ugotovimo, da noben visokonivojski predpomnilnik ne rešuje tega problema, zato razvijemo svojo rešitev, ki ohranja predpomnilnik konsistenten. Rešitev implementiramo v javanski aplikaciji in predstavimo rezultate.

• Title: Analysis and implementation of caching in Java applications

Abstract

Our work discusses problem of persistent object caching in Java application in Java Enterprise Edition environment. We begin with the theory of caching and develop a simple cache in Java programming language. We continue by presenting Java Enterprise Edition framework. We especially focus on technologies that transfer data between Java application and application server and between application server and database, because they directly affect the problem of persistent object caching. We show how changing connected objects can make cache data inconsistent. No other high level cache solves this problem, so we develop our own solution that keeps cache data consistent. We implement the solution in Java application and analyse the results.
