摘要： 传统上，关系数据库信息检索以元组级别的关系数据为检索对象，以元组连接树为检索结果，其检索效果还不够理想。为了提高关系数据库信息检索的效果，提出对象级别的关系数据库信息检索研究，介绍了研究背景和现状，阐述了基本思想及主要研究内容，为关系数据库信息检索未来的研究提供了新的思路和方法。

Abstract: Traditionally, relational DataBase Information Retrieval (DBIR) treats the tuplclevcl relational data as retrieval objects,and join trees of tuples as the retrieval results. However,the retrieval effect of DBIR is still not ideal. To improve the retrieval effect of DBIR, the research of Object-level relational DataBase Information Retrieval (DB0IR) was proposed, and its background and the state of the art were described. Furthermore, the main ideas and research directions of DB0IR were discussed. DB0IR provides a prospective method for DBIR in the future work.
Key words: Relational database,Information retricval,Object-level retrieval
