摘要
本文论述了基于光栅和基于向量的两种图形数据库的设计方法.着重论述了向量数据库的数据结构、读、写和检索算法.对三维图形数据库结构也作了探讨.
This paper deals with the grid-based and the vcctcr-based methods to design a graphic database, and conccniratcs on the discussion of structure of vector graphic database, including the algorithm for the reading, writing and retrieval. Some problems to design three dimension graphic database arc also discussed in this paper.
