基于Geodatabase的土地利用规划数据库的设计与实现

Design and Realization of Land-Use Planning Database Based on Geodatabase

利用UML建立土地利用规划数据库的模型,有利于土地利用规划数据库的结构清晰,以及类与类之间的关系明确,同时也能够方便数据库的更新和管理工作.运用UML模型直接生成基于Geodatabase土地利用规划数据库,不但有效地降低了建库的复杂性,而且能够保证数据间相互关系的正确性,同时也缩短了开发周期,便于数据库使用过程中的维护工作.从实际应用的角度出发,通过Microsoft的Visio工具建立了土地利用规划数据库的UML模型,然后根据模型生成的XML文件,在ArcCatalog中生成一个土地利用规划数据库.

The establishment of Land-Use Planning Database model by using UML is beneficial to clarify the structure of land-use planning database and the relationship between classes, and facilitates the updating and management as the same time. Directly generated Land-Use Planning Database based on geodatabase by using UML model has not only reduced the complexity of database construction effectively, but is capable of keeping the accuracy of relevance between data. Besides, it has shortened the development cycle and make the maintenance work more convenient. From the perspective of practical applications, this paper has set up a UML model of the Land-Use Planning Database, and then on the basis of the XML file a Land-Use Planning Database is generated in ArcCatalog, and some problems worthy of attention are also summed up.
