【摘要】：隨著計算機(jī)技術(shù)、數(shù)據(jù)庫技術(shù)和互聯(lián)網(wǎng)技術(shù)的不斷發(fā)展，數(shù)字化校園的網(wǎng)絡(luò)信息應(yīng)用也得到不斷的進(jìn)步。早期的數(shù)字化校園中的各個應(yīng)用系統(tǒng)采用的開發(fā)環(huán)境和數(shù)據(jù)庫不同，導(dǎo)致它們相互獨立，，且相互之間存在嚴(yán)重的信息孤島現(xiàn)象。另外各應(yīng)用系統(tǒng)的軟件開發(fā)商采用的設(shè)計理念和業(yè)務(wù)思維邏輯迥然不同，系統(tǒng)的構(gòu)架存在多樣性，導(dǎo)致不同部門之間的業(yè)務(wù)連貫性差�？傊�，各信息系統(tǒng)的業(yè)務(wù)數(shù)據(jù)不能高度共享和交換、缺乏統(tǒng)一門戶信息展現(xiàn)平臺導(dǎo)致校園網(wǎng)不能更好地為廣大師生提供優(yōu)質(zhì)的信息化服務(wù)。 本文以本校現(xiàn)有的網(wǎng)絡(luò)應(yīng)用系統(tǒng)為背景研究和設(shè)計了校園統(tǒng)一門戶系統(tǒng)。首先介紹了統(tǒng)一門戶的研究背景、目的和意義、門戶的相關(guān)理論知識及建設(shè)統(tǒng)一門戶系統(tǒng)所用的關(guān)鍵技術(shù)。然后根據(jù)統(tǒng)一門戶的設(shè)計原則，設(shè)計了統(tǒng)一門戶系統(tǒng)的整體的架構(gòu)體系和工作流程，并且著重設(shè)計了系統(tǒng)整體架構(gòu)體系中的表示層和應(yīng)用層。表示層使用Portal技術(shù)設(shè)計了統(tǒng)一門戶系統(tǒng)的登錄頁面，應(yīng)用層則主要設(shè)計了兩大功能模塊，即單點登錄模塊和異構(gòu)數(shù)據(jù)系統(tǒng)模塊。 對于單點登錄模塊的設(shè)計，除了設(shè)計了該模塊的整體工作模型和工作流程外，還設(shè)計了登錄模塊、統(tǒng)一用戶管理模塊、統(tǒng)一身份認(rèn)證模塊和注銷模塊，其中著重闡述了統(tǒng)一用戶管理子模塊和身份認(rèn)證子模塊的設(shè)計。統(tǒng)一用戶管理子模塊主要采用Grouper管理工具和基于角色的訪問控制技術(shù)；身份認(rèn)證子模塊采用基于中央認(rèn)證服務(wù)的統(tǒng)一身份認(rèn)證技術(shù)。除此以外，本文還對票據(jù)和應(yīng)用系統(tǒng)集成的安全性進(jìn)行了設(shè)計。 異構(gòu)數(shù)據(jù)集成模塊設(shè)計了它的體系結(jié)構(gòu)和工作流程，其中中間件系統(tǒng)層是通過中介器、基于LDAP協(xié)議的中間數(shù)據(jù)庫和Web Service代理器三個功能子模塊進(jìn)行設(shè)計的。由于中介器的功能是查詢分解異構(gòu)數(shù)據(jù)源和同步控制數(shù)據(jù)，所以，本論文將中介器分成查詢分解子模塊和同步控制子模塊進(jìn)行設(shè)計。 統(tǒng)一門戶系統(tǒng)在本校實現(xiàn)的結(jié)果表明，單點登錄模塊實現(xiàn)了用戶一次登錄校園統(tǒng)一門戶系統(tǒng)即可訪問被授權(quán)的應(yīng)用系統(tǒng)的功能；異構(gòu)數(shù)據(jù)集成模塊實現(xiàn)了數(shù)字化校園網(wǎng)的信息、資源和數(shù)據(jù)的共享。
[Abstract]:With the continuous development of computer technology, database technology and Internet technology, the application of network information in digital campus has been continuously improved. The development environment and database of each application system in the early digital campus are different. As a result, they are independent of each other, and there is a serious phenomenon of information isolation among them. In addition, the software developers of each application system adopt very different design concepts and business thinking logic, and the structure of the system is diverse. In short, the business data of each information system can not be highly shared and exchanged, and the lack of unified portal information display platform leads to the campus network can not better provide high-quality information services for teachers and students. This paper studies and designs the campus unified portal system based on the existing network application system of our school. Firstly, it introduces the research background, purpose and significance of the unified portal. The related theory knowledge of portal and the key technology used in constructing unified portal system. Then according to the design principle of unified portal, the whole framework system and workflow of unified portal system are designed. The presentation layer uses Portal technology to design the login page of the unified portal system, and the application layer mainly designs two functional modules. Single sign-on module and heterogeneous data system module. For the design of single sign-on module, in addition to the overall working model and workflow of the module, the login module, the unified user management module, the unified identity authentication module and the logoff module are also designed. The design of unified user management sub-module and identity authentication sub-module is emphasized. The unified user management sub-module mainly adopts Grouper management tools and role-based access control technology. The identity authentication submodule adopts the unified identity authentication technology based on the central authentication service. In addition, this paper also designs the security of the bill and application system integration. The heterogeneous data integration module designs its architecture and workflow, in which the middleware system layer is mediated. The intermediate database and Web Service agent are designed based on LDAP protocol. Because the function of mediator is to query and decompose heterogeneous data sources and synchronize control data, so, In this paper, the mediator is divided into query decomposition sub-module and synchronous control sub-module to design. The result of the unified portal system in our school shows that the single sign-on module can realize the function that the user can access the authorized application system by logging on to the campus unified portal system at one time; The heterogeneous data integration module realizes the sharing of information, resources and data in the digital campus network.
