Performance analysis of JDO in J2EE architecture

Abstract

Data persistence is one of the most important aspects of any enterprise wide application. An enterprise data persistence solution must provide speedy client transactions, ensure data integrity over time, and be able to persist data through such everyday catastrophes as system crashes and network failures. Object-oriented applications that use the Java 2 Enterprise Environment (J2EE) have a variety of persistence technologies at hand. Two prominent ones among these are entity beans and recently introduced Java Data Objects (JDO). Entity beans provide a robust container-based persistence framework attributed with various middleware services. However, over the years the use of entity beans has brought into light a number of its drawbacks. Component level inheritance and dynamic querying are not supported appropriately, and the whole approach seems to be overweight. In order to overcome these weaknesses, researchers proposed a JCA-compliant resource adapter, which allows the use of Java Data Objects (JDO) instead of entity beans and introduces a lightweight, easy to use and powerful transparent persistence layer for the Java 2 Enterprise Environment. We have presented a detailed analysis of JDO technology and compared its performance with contemporary technologies. Analysis is done to compare the response time, execution time; maximum tests per second as number of concurrent clients increases of various object persisting techniques.
