The Research On Workflow- And GIS-based Information System With The Integration Of Graphic Data And Text

After analyzing the status of Office Automation System (OAS), this paper points out that the traditional OAS is difficult in developing the information system with the integration of graphic data and text because it can't manage the huge graphic data required by some fields. At the same time, the traditional software has bad flexibility to adapt the alteration of organization or business process, so a lot of work has to be done to adapt these alterations. Geographic Information System (GIS) can manage huge spatial and attribute data easily, but it is difficult in the control of business workflow. Just on the contrary, Workflow management technology, which can control workflow easily, itself is not able to manage enormous graphic data. So the aboved short points can't be conquered only by either workflow or GIS technology. According to the development trend of computer software, and making most use of mutual supplementation of workflow and GIS technology, the author introduces new solution using component software technology and 'Plugln' to integrate GIS and Workflow to implement the information system with the integration of graphic data and text Finally, based on a case study on the construction project management information system, the concrete implementation of the integration of GIS and Workflow is introduced.It is verified that the integration of Workflow and GIS, which meets the needs of managing huge spatial information as well as enhances the flexibility of the business workflow and maintainability of the software, is an effective means to implement graphic data and text information system.The main results in this paper include:1) Considering that COMGIS has the function of managing the huge graphic data required by business processing activities, the author uses COMGIS to successfully meet the requirements of managing enormous graphic data.2) This information system has good flexibility in workflow control of the information system with the integration of graphic data and text, which makes the software much easier to be maintained.3) The integration of OA and GIS, which promotes the efficiency of the staff, is implemented based on the component software technology by using 'GIS plugln' to integrate GIS and workflow technology.
