【摘要】：目前,高校中越来越多的大学生倾向于使用移动终端来进行交流和学习。为了更好的为高校学生提供服务,本文将高校信息服务移动化呈现在终端上。由于现如今终端服务多以客户端形式出现,本文中的移动模式采用客户端形式呈现。鉴于SaaS是现如今比较流行的软营模式,通过它可以为多个用户同时提供服务,本文尝试使用一个应用实例为多个高校提供服务。将SaaS引入移动模式,会引发许多问题,如多租户架构,定制服务等。本文主要对其中的三个主要问题进行深入剖析和解决。第一个是定制服务,传统的定制菜单不适合客户端模式,本文采用定制个性化安装包的方法来为用户提供个性化服务；第二个是数据字段对接,各个租户的数据字段不尽相同,为了实现统一管理,采用元数据配置的方法将不同租户的数据字段进行统一映射；第三个是数据交换,移动终端的计算能力较弱,故客户端与服务器端只交互服务的编号,并且采用轻量级的数据格式JSON进行传输。移动网络环境带宽较小,因此采用传输数据量较小的socket方式来进行通信。本文的设计结果包括形成系统的体系结构、架构模型、功能模型以及数据库概念模型。体系结构主要包括系统的访问控制和负载均衡。架构模型将原表示层中查询本地数据的部分独立成为本地层。功能模型主要是将原有高校信息服务系统的常见模块适当移动化,形成移动客户端形式的功能模型。数据库概念模型指的是服务提供方服务器上为租户另外创建的数据库的概念模型。本文最后采用实验的方法,来验证解决定制服务方法以及数据交换问题方法的可行性。定制服务通过编码来实现对不同服务文件的组合。数据交换首先在android平台上实现客户端和服务器端的具体程序,然后通过对其之间的交换数据进行分析和比较得出实验结果。
[Abstract]:At present, more and more college students tend to use mobile terminals for communication and learning. This paper presents the mobility of university information service on the terminal. Because the terminal service appears mostly in the form of client nowadays, the mobile mode in this paper is presented in the form of client. In view of the fact that SaaS is a popular soft camp mode nowadays, This paper attempts to use a single application example to provide services for multiple universities and colleges by providing services for multiple users at the same time. Introducing SaaS into mobile mode will lead to many problems, such as multi-tenant architecture, custom service and so on. The traditional custom menu is not suitable for the client mode. This paper adopts the method of customizing personalized installation package to provide personalized service for users. The second is data field docking, the data fields of each tenant are not the same, in order to achieve unified management, The metadata configuration method is used to map the data fields of different tenants. The third is data exchange, the computing power of mobile terminal is weak, so the client and server only interact with the number of service. The mobile network environment has a small bandwidth, so it uses the socket mode to communicate with a small amount of data. The design results of this paper include the architecture of the system, the architecture model, Function model and database conceptual model. The architecture mainly includes system access control and load balancing. The architecture model makes the part of querying local data in the original presentation layer independent of local layer. The common modules of the original university information service system are properly mobile, The concept model of database refers to the conceptual model of the database created separately for the tenant on the service provider server. Finally, the experimental method is used. To verify the feasibility of solving the problem of custom-made service and data exchange. Custom-made service combines different service files by coding. Firstly, data exchange implements the concrete program of client and server on android platform. Then the experimental results are obtained by analyzing and comparing the data exchanged between them.
