Planar Dictionary Signature Method for Physical Optimization of Object-Oriented Query
支持OO查询物理优化的二维字典签名方法

Planar dictionary signature method which supports the physical optimization of o bject-oriented query is proposed in this paper. The basic design idea of the pr oposed method is introduced firstly. After the definition of planar dictionary a nd its data structure, the construction algorithm for planar dictionary signatur e and the query operation algorithms are proposed. Finally, the storage cost and the query cost models are constructed.
