【摘要】：近年来,工业化的软件复用已经从类库复用进化到了软件框架,面向领域、基于子系统级复用的软件框架已经成为软件系统中的核心元素,是软件系统其它部分依赖的基础,越来越多的软件开发商致力于软件框架的自主研发,但是这些框架往往因为商业利益和应用领域的限制,难以做到开源和通用。本文意在研究一套基于可复用子系统的、面向OA、ERP、企业管理系统的开源通用型软件框架,框架架构基于分层模式自上而下分为特定领域框架层、跨领域框架层、基础框架层和操作系统层,文章主体部分按照模式设计、模型设计、对象设计和系统实现的步骤介绍了跨领域框架层和特定领域框架层中三个子系统的设计与实现,这三个子系统分别是基于仓储-提取二阶段和杂糅型内容可融合的内容管理子系统(SM-CMS)、基于模板的数据提取与文档自动化生成子系统(EGS)以及基于角色的可复用权限管理子系统(RRMS)。在SM-CMS的研究中,文章首先分析了互联网内容的资源特性,抽象了内容对象的概念,然后提出了仓储-提取二阶段和杂糅型内容融合发布这两个新理念,最后设计了内容仓库模型、内容发布模型和融合模型,实现了互联网内容的统一存储和杂糅发布。在EGS的研究中,文章首先依据数据存储结构分析了文档类型,设计了数据提取和文档生成的工作模式,然后通过算法思想、模板设计和伪代码分析的方式介绍了Excel、Word、Xml三类代表性文档的数据提取和文档生成算法,最后验证了基于模板的Excel报表解析和Word报告生成案例的实现。在RRMS的研究中,文章首先比较了几种权限管理策略,然后分析了RRMS的工作模式,最后具体介绍了用户对象、角色对象、权力对象和控制对象的设计与实现。基于可复用子系统的软件框架结合框架架构设计和具体领域子系统的研究和实现,意在提高软件框架的复用性、扩展性和通用性,对OA、ERP、企业管理系统等领域的软件复用和生产具有重要指导意义。
[Abstract]:In recent years, industrialized software reuse has evolved from class library reuse to software framework. Domain oriented software framework based on subsystem level reuse has become the core element of software system, which is the basis of other parts of software system.More and more software developers are committed to developing their own software frameworks, but these frameworks are often difficult to achieve open source and general-purpose because of commercial interests and application constraints.The purpose of this paper is to study an open source general software framework based on reusable subsystem, which is oriented to OAA ERPand enterprise management system. Based on the hierarchical model, the framework is divided from top to bottom into a specific domain framework layer and a cross-domain framework layer.This paper introduces the design and implementation of three subsystems in cross-domain frame layer and domain-specific frame layer according to the steps of pattern design, model design, object design and system implementation.The three subsystems are the content management subsystem (SM-CMSM) which is based on warehousing and extraction stage and the hybrid content fusion subsystem, the template based data extraction and document automation generation subsystem (EGS) and the role-based reusable privilege management subsystem (RRMSN).In the research of SM-CMS, this paper first analyzes the resource characteristics of Internet content, abstracts the concept of content object, and then puts forward two new concepts of warehousing and extracting two stage and mixed content fusion and publishing.Finally, the content warehouse model, content publishing model and fusion model are designed to realize the unified storage and hybrid distribution of Internet content.In the research of EGS, the paper first analyzes the document type according to the data storage structure, designs the working mode of data extraction and document generation, and then through the algorithm thought,The methods of template design and pseudo code analysis are introduced in this paper. The algorithms of data extraction and document generation for three kinds of representative documents are introduced. Finally, the implementation of Excel report parsing and Word report generation based on template is verified.In the research of RRMS, this paper first compares several privilege management strategies, then analyzes the working mode of RRMS, and finally introduces the design and implementation of user object, role object, power object and control object.The software framework based on reusable subsystem is combined with the framework design and the research and implementation of specific domain subsystem, which aims to improve the reusability, extensibility and generality of the software framework.It has important guiding significance for software reuse and production in the fields of OAA ERP, Enterprise Management system and so on.
