Research And Application Of Developing Technology For Web Application Based On SPS2003

SharePoint Portal Server2003(briefly Called SPS2003) is a security, flexible door serverfor enterprise. It's used to integrate SharePoint site, information and application into a singledoor location. User can customize through door's content and layout for individual, and findrelative information faster. At present, many industries and governments have beganproviding with information share and application service based on SPS2003, and havefounded virtual organs or virtual firms in order to share mass resource.This paper researches on some technology problems about Web application on SPS2003.The key of second development based on SPS2003 is development of custom Web Part.However, Microsoft doesn't provide with visual interface for development of custom WebPart. Through reseaching on Web Part and user control, user control wrapper is designed tomake development of custom Web Part visual, to make user control and its properties editable,to make duplex transmission of data between user controls, and therefore to make greatimprovement for project's developing process.Besides that, Web Service and XSLT are combined to resolve the problem of finding outand choosing outer data in Infopath. Research on technology of SPS2003's single sign-on,which can integrate back-end applications well. Resolve the problem of Website migrationthrough matching domain user and SPS2003 user. As for security, make a certain research infour sides: authentication, authorization, code access security and starting up ssl and relativeideal configuration for sso.The above technology is well applied in MIS for public service platform in medicalvalley zhangjiang, shanghai. The system is the application with B/S model and sub systemcontracts management divided into three layers: presentation layer, operation logic layer anddata layer. What's more, operation logic layer is divided into operation sub layer and dataaccess sub layer. Presentation layer is denoted by user control wrapped by user controlwrapper. In data access sub layer, abstract access to a single table, so that it becomesconvenience to select, to update based on key columns and sign columns, to insert and todelete. Bargaining clinets management and resources management sub systems are developedby SPS2003's form library and techonolgy of searching outer data in Infopath plays animportant role. This system follows rule of software project, and is analyzed and designed by UMLmodel. In stage of design, user's need is described by use case diagram; in stage ofimplementation, SPS2003, Infopath 2003, ASP.NET technology and SQL2000 database areused and project phase one has been finished successfully.
