【摘要】：共青團干部業(yè)務培訓工作,在共青團干部的成長過程中發(fā)揮著重要的作用。開發(fā)共青團干部在線培訓信息系統(tǒng),能夠有效克服傳統(tǒng)培訓工作的缺陷,為共青團干部培訓工作提供信息化培訓提供技術支持。本文基于河南某市共青團干部培訓工作的實際需求,設計開發(fā)共青團干部在線培訓信息系統(tǒng)。調研分析了培訓信息系統(tǒng)用戶的實際需求,根據用戶需求將系統(tǒng)劃分為四個功能模塊,包括:系統(tǒng)管理模塊、課程管理模塊、在線學習模塊和綜合業(yè)務模塊。將系統(tǒng)使用者劃分成為系統(tǒng)管理員、培訓管理員、學員等多種參與者,創(chuàng)建了參與者需求分析UML用例模型,實現了對于參與者功能用例需求的圖形化描述。分析了軟件系統(tǒng)的性能指標,以各項性能指標保障功能的穩(wěn)定運行。在分析系統(tǒng)各項功能進行數據持久化保存的基礎上,設計了數據庫結構模型。數據庫模型分為ER模型與表結構模型,其滿足數據庫設計3NF的要求,能夠保障系統(tǒng)運行期具有較少的數據冗余并降低數據讀寫異常發(fā)生的概率。以J2EE作為系統(tǒng)開發(fā)技術平臺,運用Struts與Hibernate技術框架搭建開發(fā)環(huán)境。按照MVC設計模式將軟件系統(tǒng)劃分為View、Action和DAO的三層技術架構。通過軟件功能層次結構的劃分,達到提升軟件功能內聚性并降低內部耦合程度的目的。設計了軟件功能實現所需的業(yè)務處理類和方法,并設計了不同層次類之間的調用時序模型。構造了應用程序代碼和系統(tǒng)功能界面,實現了系統(tǒng)的部署運行。設計了系統(tǒng)測試用例,通過檢測確定系統(tǒng)的各項指標達到設計要求。共青團干部在線培訓信息系統(tǒng)運行穩(wěn)定,滿足了干部培訓工作的各項要求,有效提升了培訓工作的信息化程度。
[Abstract]:The professional training of Communist Youth League cadres plays an important role in the growth process of Communist Youth League cadres. The development of online training information system for Communist Youth League cadres can effectively overcome the defects of traditional training and provide technical support for information training for Communist Youth League cadres. Based on the actual needs of the cadres training of the Communist Youth League in Henan Province, this paper designs and develops the online training information system of the cadres of the Communist Youth League. The actual needs of the users of the training information system are investigated and analyzed. According to the needs of the users, the system is divided into four functional modules, including: system management module, course management module, online learning module and integrated business module. The system user is divided into system administrator, training administrator, student and other participants. The UML use case model of participant requirement analysis is created, and the graphical description of participant functional use case requirements is realized. The performance index of the software system is analyzed to ensure the stable operation of the function with each performance index. Based on the analysis of the functions of the system for data persistence preservation, the database structure model is designed. The database model is divided into ER model and table structure model, which can meet the requirements of database design 3NF, ensure that the system has less data redundancy and reduce the probability of data reading and writing anomalies. Taking J2EE as the system development technology platform, using Struts and Hibernate technology framework to build the development environment. According to MVC design pattern, the software system is divided into three layers of View,Action and DAO. Through the division of software function hierarchy, the purpose of improving software function cohesion and reducing the degree of internal coupling is achieved. The business processing classes and methods needed for the realization of software functions are designed, and the call timing models between different levels of classes are designed. The application code and system function interface are constructed, and the deployment and operation of the system are realized. The test case of the system is designed, and the indexes of the system are determined to meet the design requirements. The online training information system of Communist Youth League cadres runs stably, meets the requirements of cadre training, and effectively improves the information level of training work.
