This International Standard specifies the basic format of singlehit decision tables and the relevant definitions, together with recommended conventions for preparation and use. NOTES 1 This International Standard is concerned with the use of decision tables in the context of the documentation of computer-based information systems. It is not concerned with other uses, such as for the representation of program statements. 2 The format and conventions for the preparation and use of “multiple-hit” decision tables are outside the scope of this International Standard.
