Implementation of Non-Java Based Interfaces to Embed Existing Models in Spatial Decision Support Systems - Case Study: Integration of Ms Excel-Models in Iwegs
Source: University of Bonn
This paper shows the programming and usage of computer based interfaces to embed models in modern SDSSs. The special focus is on the development and implementation of non-Java based interfaces which couple already existing MicroSoft (MS) Excel-based models to individual designed SDSSs. To access MS Excel files within these developed systems, Java API POI-HSSF (by Jakarta) is used. HSSF provides a way to create, modify, read and write .xls-spreadsheets. Besides that, this library supports cell-functions and -formulas. Based on the state-of-the-art software development and design approach MVC (Model-View-Controller), the interfaces are developed as processors.
