摘要：

Requirements to software systems, including databases, often change. It is tempting to design a database according to very abstracts concepts. The generic design, which is called "universal database design", allows us to record all possible facts in terms of object types, objects, attributes, attribute values, and relationships. This kind of design arguably simplifies the recording of new kinds of facts. However, the flexibility comes with a price. Existing studies point mostly to the performance problems and complexity of queries. We found twelve different problems with this kind of design. In this paper, we present the analysis of the advantages and disadvantages of the use of the universal design.
