Construction and Realization for Multi-dimensional Database Based on RDBMS
Abstract: 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 spatialdata and
attribute data, which results into many problem: the low query efficiency, the
higher managementdifficulty, the problem of data communion, etc. Object
oriented pattern, however, still need furtherresearch. 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 (OracelSpatial), 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.
