Abstract

Since object-oriented programming has become dominant in application development, there has been the recurring issue of an impedance mismatch between the way programmers manipulate objects in memory, and the way they are made persistent in secondary storage. To address the aforementioned mismatch, a number of object-oriented database (OODB) systems were developed that embodied transparent (or orthogonal) persistence in existing programming languages (e.g., Gemstone in 1987), with current albeit simplified successors such as OJB and Hibernate.
