Lin Bi · Journal of Sichuan University · 2010
This paper mainly researches how to establish semantics layer between report designer and enterprise data source and how to define the data model in semantics layer. This model has sealed the data source technical detail. When users' design report based on the semantics layer, they only need to drag and drop semantic layer element simply, do not need to compile complex expression or SQL. The using of semantics layer not only brings enormous convenient for users operation, but also strengthens the security of enterprise data. In the model has established the view incidence relation in the field, the relational automatism in the report, does not need to carry on the view to connect may design the multiple source report, which enormous enhancement complex report computational efficiency.
