| With increasing demand for the large capacity storage and high performance computing, updating hardware through the traditional way to improve performance is not appropriate, especially for the small and medium enterprises. Because they do not have enough hardware and software services. Cloud computing has become one of their best way to solve the problem.Cloud computing is emerging technology in recent years, Google, Microsoft, IBM and other companies to speed quickly launched its own cloud computing platform, and introduced many products based on the cloud platform. Such as Google's search engine and map applications. We fully enjoy the convenience the emerging technology brings to our life.But many small enterprises do not have enough resources to develop cloud-based applications, on the other hand, their business needs is complex and diverse, so developing the needs of their own custom applications based on cloud computing faces many difficulties , since the use of traditional software development methods to develop such applications are more time-consuming and resource consuming. According to the characteristics of enterprise information system, model-driven development techniques is a better way to solve this problem, software development jobs to build the main model, the software can quickly respond to the demand model, and the model can be quickly posted to the appropriate platform.In this paper, I focus on the cloud architecture and programming model. By analyzing relational database and database in cloud platform, propose a new data management technology, two database collaborative processing technology. Information systems in the use of this technology can handle full advantage of both platforms. On this basis, I give an example to research the detail.In this paper, the develop cloud is a technology for the Information application of small enterprises, using model-driven technology to construct application based on relational database and the cloud platform rapidly. Which presents a field of information technology for field-based model-driven software development methods, gives the modeling method, and on this basis, a detailed study of the domain model based model transformation methods, including relational databases, respectively, to And cloud platform, database conversion, transformation rules are given. Finally, the field model is presented based on the specific implementation platform, the platform can be achieved through the use of modeling, model transformation, code generation. Though this we can achieve rapid construction of cloud-based applications. |
