A Requirement Description Specification for Automatic Customization of Data Products

In order to improve the efficiency of understanding and realizing requirements in the process of data product customization, this paper proposes a data product customization method based on specification requirements description. According to this method, data product requirements are firstly proposed according to the specification, and then data schema mapping is automatically constructed based on the requirements, so as to carry out data product production automatically. In this paper, several important links of this method are described in detail, including the custom requirement description specification, the data schema mapping method based on requirement description and the production of data products based on schema mapping. The result show that this method is feasible for relational structured data and can obviously save the development cost of customized software for data products.
