Abstract: Object-relational mapping (ORM) is a mechanism to link classes of an object-oriented (OO) programming language to tables of a relational database management system (RDBMS). When designing a mapping for an application’s domain model, different strategies exist to map associations and inheritance relationships to database tables. Each strategy has a different impact on the application’s quality characteristics. Developers need to understand the impact of a mapping strategy to make informed decisions. In the absence of cost models to quantify the impact, guidelines and best practices have been developed to allow differentiated considerations of strategies. However, looking closer at these guidelines, two major flaws become apparent - incompleteness and inconsistency. In this paper, a comprehensive literature study is presented, which includes an analysis of guidelines and best practices from industry and academia. We propose a consolidation approach, which identifies relevant aspects of mapping strategies that impact a system’s quality characteristics. The approach derives a multi-level organization, which describes the relation between mapping strategy aspects and quality characteristics of a system. The identified mapping aspects and the organization can serve as a framework to improve existing guidelines and to resolve inconsistencies. (More)
