摘要
A system, method and software product retrieve a formatted data value from a data layer to a business logic layer by invoking a formatted variable abstraction procedure from the business logic layer, passing at least one parameter to the formatted variable abstraction procedure (the at least one parameter identifying a formatted system variable), and building a dynamic statement based upon the formatted system variable such that execution of the dynamic statement: accesses a formatted variable table based upon the formatted system variable to locate information relating to the formatted system variable; retrieves one or more data items based upon the information; formats the data items to form the formatted data value based upon the information; and returns the formatted data value to the business logic layer.
