What is DDDplus?

DDDplus, originally cp-ddd-framework(cp means Central Platform：中台), is a lightweight flexible development framework for complex business architecture.

一套轻量级业务中台开发框架，以DDD思想为本，致力于业务资产的可沉淀可传承，全方位解决复杂业务场景的扩展问题，实现中台核心要素，赋能中台建设。

融合了前中台复杂生态协作方法论，充分考虑组织架构、技术债、学习门槛、可演进性、运维成本和风险而开发的，解决业务开发痛点，是中台架构的顶层设计和完整解决方案。

Current status

Used for several complex critical central platform projects in production environment.

多个复杂的中台核心项目生产环境下使用。

Features

• Based on DDD, but beyond DDD
• 14 key business abstractions cover most complex business scenarios
• Full layered extensibility
• Empowers InnerSource
• Provide maven archetype that generates a DDDplus integrated project
• Total solutions oriented
• Covers business assets full lifecycle

核心特性：

• 以DDD架构思想为本，面向复杂业务场景架构设计
  • 通过代码框架提供足够约束，让DDD不再仅停留在思想层面
  • 只引入弱依赖的 IDomainModel，弱化其他概念，降低DDD上手门槛
  • 提供 dddplus-archetype，直接生成最佳实践的脚手架代码
  • DDD分层架构上增加一层spec layer，解决前中台协同问题
