摘 要：異構(gòu)信息系統(tǒng)在高校中的大量存在阻礙了數(shù)據(jù)資產(chǎn)整合與信息交互，面向服務(wù)的架構(gòu)（SOA）的出現(xiàn)及在企業(yè)中的廣泛采用為解決此問題提供了思路，但在高校中實施SOA存在難度大、難以形成以SOA為基礎(chǔ)的信息化生態(tài)的問題。針對這些問題，提出主數(shù)據(jù)管理驅(qū)動的SOA建設(shè)方案。首先，在數(shù)據(jù)層面運用主數(shù)據(jù)管理平臺對校級核心數(shù)據(jù)資產(chǎn)進行建模和整合;為實現(xiàn)數(shù)據(jù)同步和消費，并解決其中存在的協(xié)議轉(zhuǎn)換及服務(wù)鑒權(quán)問題，提出了基于企業(yè)服務(wù)總線的解決方案;然后，針對遺留“信息孤島”系統(tǒng)進行SOA改造，提出主數(shù)據(jù)驅(qū)動的建設(shè)方案。實驗結(jié)果表明單用戶、10用戶、100用戶及10000用戶并發(fā)下的平均延遲分別為8、11、59及18ms，表明在不同并發(fā)場景下所提方案性能均滿足高校業(yè)務(wù)需求。實施結(jié)果表明，數(shù)據(jù)資產(chǎn)整合和信息交互問題得到了解決，因此方案具有可行性。

Abstract：

The existence of heterogeneous information systems in colleges and universities hinders data assets integration and information interaction. The emergence of Service Oriented Architecture （SOA） and its widespread adoption in enterprises provide ideas for solving this problem， while it is difficult to implement SOA and form an SOA-based informational ecosystem in universities. In response to these problems， an SOA construction scheme driven by master data management was proposed. Firstly， a master data management platform was used to model and integrate the core data assets at the data level. In order to realize data synchronization and consumption， and solve the problem of protocol conversion and service authentication in the process， an enterprise service bus based solution was proposed. Then， in order to the transform the legacy “information island” systems to SOA， a construction solution driven by master data was proposed. The experimental results show that the average latency with concurrency single user， 10 users， 100 users and 10000 users is 8， 11， 59 and 18ms respectively， which indicates that the performance of the proposed scheme meets the need in different concurrent scenarios. The implementation results show that the data assets integration and information interaction problems have been solved， which proves that the scheme is feasible.

教育信息化已成為信息化建設(shè)重要領(lǐng)域之一。然而國內(nèi)教育信息化在系統(tǒng)架構(gòu)及數(shù)據(jù)價值發(fā)揮上與國外高校及銀行、保險、證券及互聯(lián)網(wǎng)等行業(yè)存在較大差距，一個突出困境就是“信息孤島”問題。由于學(xué)校各部門在建設(shè)信息系統(tǒng)時缺乏頂層設(shè)計，未考慮系統(tǒng)間協(xié)同與互操作，因此業(yè)務(wù)系統(tǒng)上線之時就具有獨立、異構(gòu)、封閉等屬性，大量資源無法實現(xiàn)應(yīng)有價值，阻礙了跨部門業(yè)務(wù)處理及智慧校園的進一步建設(shè)。……
