Nowadays, with the development of software technology and Internet technology becoming more and more mature, a new model of software service has emerged in the 21st century.Software is Service SaaS (Software as a Service).In the software as a service model, the software is operated and maintained by SaaS service providers.It meets the needs of users by hosting, eliminates the cost of purchasing IT infrastructure, and exempts the cost of purchasing traditional legitimate software;Compared with the traditional framework, ABP framework follows the principle of DDD (Domain Driven Design).It monitors and studies the process of software development and maintenance.Domain model can maintain the business rules and data consistency between data in the domain, make it more scientific, standardized and enable enterprises to better achieve business goals.Therefore, this paper proposes the design and implementation of the library management system based on ABP framework SaaS model.The main contents include business analysis, system analysis, system implementation and system testing.The system first realizes the necessary auxiliary function, and then realizes the main function of storage management.Finally, the test plan was created through TestManager to verify the feasibility of the system's functionality.This makes up for the low reusability, high complexity and huge upfront cost and late maintenance expenditure of the traditional general warehouse management system.%目前软件技术和互联网技术发展的越来越成熟, 在21世纪兴起了可以称为全新的一种软件服务的模式, 软件即服务SaaS (Software as a Service) .在软件即服务模式下, 软件由SaaS服务提供商运营和维护, 以托管的方式满足用户的需要, 省去了用户购买IT基础设施的费用, 免除了传统正版软件的购买支出;与传统框架相比, ABP框架遵循DDD (领域驱动设计) 原则, 对软件开发和维护进行过程监控和研究, 领域模型可以维护领域内数据之间的业务规则以及数据的一致性, 可以使其更加科学化、标准化、使企业能够更好地实现商业目标.因此提出基于ABP框架SaaS模式入库管理系统的设计与实现, 主要内容包括业务分析, 系统分析, 系统的实现和系统测试.系统首先实现了必须的辅助功能, 其次实现了仓储管理的主要功能.最后也通过TestManager创建测试计划, 验证系统功能的可行性.从而弥补传统一般仓储管理系统的代码重用性低, 复杂性高以及巨大的前期成本和后期维护支出.
