Software specification, tabular expressions, software cost reduction, software requirements


Tabular Expressions and the Software Cost Reduction (SCR) method are table-based specification techniques. Both of them were successfully used in practice, especially to formally specify software requirements. Tabular Expressions have rather precise semantics, while SCR semantics are more intuition based. In this paper, we want to improve SCR semantics. For that, we show how to convert the SCR tables into tabular expressions. The conversion that we came up with allows the SCR tables to inherit the semantics of tabular expressions. Hence, the converted tables are more readable, and more efficient.
