Abstract: Information retrieval from a database is the backbone of many applications. For building object-oriented systems with a relational persistence engine, a common approach is to use an object-to-relational mapping library for handling the mismatch between object-oriented and relational data models. These components should make the application programmer oblivious to the choice of relational database. To study the effects of transparent persistence, we conducted a randomized, controlled study for 16 students, who were given a number of maintenance tasks on a sample software. For half of attendees, the sample software was written using the transparent persistence approach. For the second half the sample software used a self-configuring component for automatically generating database queries. We found out that the group using transparent persistence were performing worse than the group using self-configuring queries. Attendees in both groups were using the same amount of time for perform ing the given maintenance tasks, but the transparent persistence group was outperformed by a factor of three in the number of correct submissions. The use of transparent persistence turned out to be a major error source. This gives us a reason to doubt the usefulness of transparent persistence in the long run. (More)
