Construction and Realization for Multi-dimensional Database Based on RDBMS

Based on ArcSDE, this paper has proposed a new construction and management method for spatial database which has better performance than the traditional method. Up to now, there are four kinds of management about GIS database:whole file pattern, the combination pattern of file and DBMS, whole DBMS pattern and object oriented pattern. In fact, the two former ones is managed by separating spatial data and attribute data, which results into many problem: the low query efficiency, the higher management difficulty, the problem of data communion, etc. Object oriented pattern, however, still need further research. So, for a long space it is still need DBMS co-work to constructe spatial database.ArcSDE is a server software product of ESRI used to access massively large multiuser geographic databases stored in relational database management systems (RDBMS). Being different from other database product (Oracel Spatial), ArcSDE provides a suite of services that enhance data management performance, extend the range of data types that can be stored in a RDBMS, enable schema portability between RDBMSs, and offer configuration flexibility.
