Abstract
In this paper we propose a novel model for XML data management, which is called TROS (Text Relational Object Semantic), to overcome the shortcoming of directly storing XML data in relational databases. TROS consists of three layers, the top of which is object semantic layer, the middle relational data management layer and the bottom is text file management layer. We also consider the implementation issues of this model. By analyzing the semantics of queries posed by users, we propose a novel object-relational index structure, which can efficiently improve query performance by avoiding join operations between relations. In the model, relational queries result support corresponding document content’s queries.
