摘要
集成型空间数据库的构建过程中,常涉及到空间数据的非结构化特征问题。总结了目前克服此问题的两种技术,即面向对象技术与中间件技术,并对商业化中间件中的空间数据引擎作了标准性、存储结构与图层管理三方面分析。给出了采用空间数据引擎的应用实例,提出了急需解决的问题。
During designing of spatial database with integrated architecture, we are always related to nonstructural problems. At the base of summarizing two techniques overcoming this problems which are object\|oriented technique and middle\|piece technique, author analyzed standardization, memory structure and layer management of spatial data engine in the commercial middle\|piece, gave the example of spatial data engine and put forward the problems which are starved for solved.
