摘要：
Comparing with basic data model, statistical data model is changeful in database application system. How to describe the structure of statistical data has important sense. This paper analyses statistical data structure, designing a data definition language S-DDL which can describe statistical model. This language has SQL-like structure, could describe different kinds of statistical data structure, and generate statistical result. Also presents a statistics generating algorithm and an example of statistical data definition.
