【摘要】：隨著信息技術(shù)的不斷發(fā)展,信息化建設(shè)已經(jīng)深入到各行各業(yè),相互之間信息溝通與協(xié)同工作的實(shí)時(shí)性越來(lái)越重要�；赪eb的協(xié)同編輯系統(tǒng)正是為了解決原有文字編輯系統(tǒng)的低效、繁瑣等問(wèn)題而開(kāi)發(fā)的,用戶(hù)僅需要使用瀏覽器即可協(xié)同編輯同一份文檔,并且可以實(shí)時(shí)看到其他用戶(hù)的編輯結(jié)果,支持多種智能設(shè)備,極大地提高了工作效率。但由于信息的傳輸和信息方式發(fā)生了很大變化,同傳統(tǒng)協(xié)同模式中對(duì)資源的管理有很大程度的不同,在有關(guān)用戶(hù)和文檔等資源的管理方面尤為明顯。與此同時(shí),基于Web的協(xié)同編輯系統(tǒng)需要較高的實(shí)時(shí)性和一致性,以保證多用戶(hù)之間的信息狀態(tài)能夠?qū)崟r(shí)同步。針對(duì)上述問(wèn)題,本文結(jié)合國(guó)內(nèi)外關(guān)于資源管理的研究資料,提出一套關(guān)于在基于Web的協(xié)同編輯系統(tǒng)中進(jìn)行資源管理的方案。通過(guò)用戶(hù)組和角色分配的方式管理用戶(hù)權(quán)限,設(shè)計(jì)系統(tǒng)傳輸數(shù)據(jù)的格式,減少傳輸?shù)臄?shù)據(jù)量,分析用戶(hù)操作沖突的場(chǎng)景并使用操作轉(zhuǎn)換方法實(shí)現(xiàn)一致性控制。本文詳細(xì)分析該方案的設(shè)計(jì)原理和模型,將資源管理子系統(tǒng)設(shè)計(jì)為用戶(hù)管理、數(shù)據(jù)同步和數(shù)據(jù)存儲(chǔ)三個(gè)模塊,使用Node.js以及WebSocket技術(shù)分別進(jìn)行實(shí)現(xiàn)。同時(shí)針對(duì)用戶(hù)會(huì)話(huà)管理、文檔和用戶(hù)操作記錄的保存,以及協(xié)助其它子系統(tǒng)的輔助功能進(jìn)行設(shè)計(jì)并實(shí)現(xiàn)。本文首先研究了基于Web的系統(tǒng)編輯系統(tǒng)的特點(diǎn),分析和總結(jié)了資源管理子系統(tǒng)的功能需求和架構(gòu),并從實(shí)現(xiàn)所用的技術(shù)路線(xiàn)和關(guān)鍵技術(shù)等方面做出詳細(xì)的介紹。最后對(duì)基于Web的協(xié)同編輯系統(tǒng)中資源管理子系統(tǒng)進(jìn)行測(cè)試,驗(yàn)證了系統(tǒng)的正確性和實(shí)用性。
[Abstract]:With the continuous development of information technology, the construction of information has been deep into various industries, and the real-time information communication and collaborative work between each other is becoming more and more important. The collaborative editing system based on Web is developed to solve the inefficient and tedious problems of the original text editing system. Users can only use the browser to co-edit the same document. Moreover, the editing results of other users can be seen in real time, and many intelligent devices can be supported, which greatly improves the working efficiency. However, due to the great changes in information transmission and information mode, there is a great difference between the traditional cooperative mode and the management of resources, especially in the management of related users and documents. At the same time, the cooperative editing system based on Web needs high real-time and consistency to ensure the real-time synchronization of multi-user information state. Aiming at the above problems, this paper puts forward a plan of resource management in the collaborative editing system based on Web based on the domestic and foreign research data on resource management. The user rights are managed by user group and role assignment, the format of system data transmission is designed, the amount of data transmitted is reduced, the scene of user operation conflict is analyzed, and the consistency control is realized by operation conversion method. In this paper, the design principle and model of the scheme are analyzed in detail. The resource management subsystem is designed into three modules: user management, data synchronization and data storage, which are implemented by Node.js and WebSocket technology respectively. At the same time, it is designed and implemented for user session management, document and user operation record preservation, and assist other subsystems. This paper first studies the characteristics of the system editing system based on Web, analyzes and summarizes the functional requirements and architecture of the resource management subsystem, and introduces in detail the technical route and key technologies used in the implementation. Finally, the resource management subsystem of collaborative editing system based on Web is tested to verify the correctness and practicability of the system.
