Establishment of General Data Base Process System

In this paper, general data base process system (DBPS) is estblished, in which computer BASIC language and data base dBASE is combined. DBPS consists of a main module and five function modules, which can finish inquiry, transformation, statistics, replacement and printing for data base. Decomposition calculation of logic expression, relation expression and algebraic expression inputed from keyboard in the system with BASIC language is realized, and the problem of preservation of original records in statistics result is resolved by setting up virtual layer. So this system has the characteristics of strong function which is flexible and convenient in use.
