首发时间:2011-03-07
摘要:属性数据是GIS重要的空间数据类型,从大多数的操作系统来看,查询操作在各种数据库操作中占比重较大,其效率的高低直接影响到数据库性能的好坏。然而常见的属性查询功能常具有互操作性差、查询能力低,不便筛选等智能化低下的缺点。本文系统的研究了常见的属性查询途径的优缺点,基于ArcGIS Engine 9.2平台,提出了一种新型的便于对数据分层、分性、分区组织的属性查询方案,并简要阐述了该方案的实现过程。

Optimization of Query Property Based on ArcGIS Engine
Abstract:The attribute data is an important GIS space data type, looking from the majority operating systems, the inquiry operation is more and more important in each kind of database operation, its efficiency height immediate influence to database performance quality. However, common property query function usually have poor interoperability, inquiry ability to be low,linconvenient screening and so on. This paper show the advantages and disadvantages of traditional attributes inquires, and based on ArcGIS engine 9.2 platform, puts forward a new kind of organization of attribute which is easy to show the data by different layers, positions and object.
