The invention discloses an enterprise-class system research and development framework. The framework comprises a data layer, a service layer and a business layer, wherein the data layer comprises a relational database assembly, a non-relational database assembly, a buffer database assembly, a data computation assembly and a data application assembly; the service layer comprises an interface service assembly, a communication service assembly, a configuration management assembly, a search engine assembly, a calculation service assembly, a universal service assembly, an authority system assembly, a message service assembly, a storage service assembly, a log service assembly, a safety audit assembly, an authentication service assembly, a dispatch service assembly and a reporting service assembly; the business layer comprises an order system, a user system and a fund system; and the service layer is used for encapsulating data logic of the data layer and converting the data logic into a service system of the business layer. According to the enterprise-class system research and development framework, the development cycle is shortened, the development and maintenance costs are effectively lowered, and the maintainability is good.
