An Open GIS Consortium (OGC) white paper said that the future vision for sharing data might look like this: Each of the smaller counties or towns hosts its own online GIS. Each uses software and a data model selected to best meet its local needs, which is the objective of this paper studies to close with. This paper gives a model based on Oracle Spatial, within a local government or enterprise the spatial data is centralized storage, and with metadata interoperability, which enables organizations to use the right tool for the job while eliminating complicated data transfers and multiple copies of the same data throughout the enterprise or department. This paper has realized MapInfo and ArcGIS work together under the same oracle spatial database use trigger and storage process. And at another hand, with the situation of between the departments or enterprises this paper gives a three-tier structure solution: spatial data server, application server and application client. The application server is a mediation system, this model uses oracle application server as the mediation system, and through the application server the application client sends WMS or WFS request and get the map server for background application. The three-tier structure model exposes a GIS portal which is an online GIS for outside of the department. Any client can request the server if it accords with WMS or WFS specification.
