Abstract: To promote the development and commercial application of data mining,with the help of the combinations of the cloud computing technology,domain engineering and data mining based on the domain-driven design and the cloud computing framework,a domain-oriented data mining cloud platform framework was proposed and the mechanism of domain-oriented data mining services under cloud computing environment was given.Also,the development mode of domain-oriented data mining cloud platform services was advocated and the development process of domain-oriented data mining services from the view of software development and life cycle was described.
