【摘要】：随着互联网技术的迅速发展,越来越多的招标企业逐渐运用线上招标管理系统,以达到有效地组织和管理整个招标企业的业务流程的目的。因此,本文旨在设计和实现了一套服务模式驱动的云招标多租户管理子系统。其中,该管理子系统引入Web和云计算等相关技术,实现了基于SaaS (Software as a Service:软件即服务)的服务模式,提高了子系统的高扩展性和高灵活性。经过需求分析,在云招标多租户管理子系统中,主要实现了租户信息管理、服务器管理以及服务账单管理等功能模块。系统中所有功能模块共同作用,除了提供对多租户基本信息的统一化管理外,还提供了可灵活匹配多租户个性化需求的服务定制配置,方便租户按期租用服务。另外,使用分库技术实现了对业务数据库进行数据隔离,即租户业务系统与业务数据库一一对应。这样一来,既可以保证了租户信息的隔离安全性,也可以有效地为多租户提供个性化服务。为了更好地为多租户提供有效服务和体验,在云招标多租户管理子系统的设计与实现的过程中,主要实现了面向多租户的分布式服务架构和自动化部署两大关键技术。其中,前者依次实现了服务信息的跨域传输、单实例多租户结构以及多租户的数据隔离,从而实现了对分布在不同区域的租户提供有效管理和服务;后者则依次实现了自动为租户申请域名、建立站点以及部署业务数据库,从而消除了人工部署业务子系统的流程,提高了管理子系统的管理效率。
[Abstract]:With the rapid development of Internet technology, more and more bidding enterprises gradually use online bidding management system to effectively organize and manage the business process of the whole bidding enterprise. Therefore, this paper designed and implemented a multi-tenant management subsystem driven by service mode. The management subsystem introduces Web and cloud computing technologies to realize the service mode based on SaaS (Software as a Service: software as a service, and improves the high scalability and flexibility of the subsystem. Through requirement analysis, in the multi-tenant management subsystem of cloud bidding, the function modules such as tenant information management, server management and service bill management are implemented. All the function modules in the system work together, besides providing unified management of the basic information of multi-tenant, it also provides the service customization configuration which can meet the individualized requirements of multi-tenant flexibly, which is convenient for tenants to rent on time. In addition, the sub-database technology is used to realize the data isolation of the service database, that is, the tenant business system corresponds to the service database one by one. In this way, it can not only guarantee the isolation security of tenant information, but also effectively provide personalized service for multi-tenant. In order to provide effective service and experience for multi-tenant, two key technologies of multi-tenant oriented distributed service architecture and automatic deployment are implemented in the design and implementation of cloud bidding multi-tenant management subsystem. Among them, the former realizes the cross-domain transmission of service information, single-instance multi-tenant structure and multi-tenant data isolation in order to provide effective management and service to tenants distributed in different areas. The latter realizes automatic domain name application for tenants, establishment of site and deployment of business database, which eliminates the flow of manual deployment of business subsystem and improves the management efficiency of management subsystem.
