| The technology of component-based ware resolves some problems of distributed and reusable software. COM and CORBA and EJB are the three most prevalent standards of software component technology. Especially, COM handles these problems elegantly at Windows platform.The management of software components and transactions provided by MTS enhanced the flexibility and reliability of component-based distributed three-tier database applications. Combining the advantages of COM and MTS,COM+ has been the base of Windows2000.On the background of these technology , The paper studied component-based software's developing model, and applied it to the development of a component-based distributed three-tier database application. Business logic layer and presentation layer components are obtained through partitioning modules of the High-school research management information system in detail using components technology. These components are designed and the specific implementation of component technology is validated by experiment of developing the intelligence and High-school research management information system under the Delphi platform. |
