The JDO Persistence Model

Seminar paper from the year 2005 in the subject Computer Science - Programming, grade: 1,3, University of Potsdam, course: Seminar Systemmodeling, language: English, abstract: JDO is a specification for design object domain models without having to consider the persistency of data. The main target of JDO is the abstraction of concrete data storage solutions and the provision of transparent and implementation-independent solutions for persistent data. Starting with an introduction to the architectural model of Java Data Objects, benefits of this approach and the realization by a tool-based enhancement are outlined. Furthermore, the API itself is in focus of examination, main programming interfaces and the JDO-QL will be discussed. Finally, it is aimed to give an outlook on the up-coming JDO 2.0 specification.
