Based On Common Analysis Of Mis Design And Realization

The article first introduces the general situation, the characteristics, classification of the management information system and application realm, secondly points out that the management information system is not an isolated course, but has the inseparable contact with many related courses; Lastly introduces the latest outcome all over the world in brief.After analyzing many of MIS, The article finds commonness existing in every MIS can be abstracted. Based on above thinking, it Puts forward the commonness concept, namely general using, and discusses all kinds of areas on MIS in detail from the process of development of system programming, setup of programming software, each function mold for realization, and the operation of software. After a commonness analysis and the contrast with the traditional systematical method, It puts forwardMIS method--wooden blocks method based on the foundation of commonness, whosecomplication can shorten the developing period of the software availably, and reduce the developers' workload. In MIS function mold , the gross mold is a container for each function sub-mold piece, and a " soft main board" that can be realized. Each function sub-mold is a homologous " soft slot". By adopting wooden blocks method, the function of the software" plug-and-play" can be realized through inserting the sub-mold into a" soft slot" reserved in the " soft main board" for sub-mold.Commonness theories offers a theoretical basis for the rapid growth of software .But real software of industrialization and assembling must realize the software reuse. Software reuse is a key technique to increase quality of software product and software's production efficiency. The software reuse's main technique is designing for software component. In the text, treatise techniques concerning designing for software component are discussed: including characteristics of component, five levels of structure based on component design, and methods of component construction. The concept of the software reuse is very extensively, object oriented (0-0) technique is a successful example. The combination between object Oriented and software reuse produces software reuse' s technique based on 0-0, which is decided by the characteristics of 0-0. Three kinds of reuse's technique and ways to promote software reuse of software reuse' s technique based on 0-0.Finally combined with the specific environment of development, it elucidates how to develop component under the development environment of Delphi , and gives a specific accomplishing method for MIS based on component.
