This e-book introduces SpecDB, an clever database created to symbolize and host software program requisites in a machine-readable structure, in response to the rules of man-made intelligence and unit checking out database operations. SpecDB is established through computerized clever instruments. the 1st immediately generates database constraints from a rule-base in SpecDB. the second one is a opposite engineering software that logs the particular execution of this system from the code.

The post conditions of that instance are stored in the Runtime SR Post Conditions table, using that same instance number. 4. Entities for Specific Software Requirements Fig. 9 SpecDB 41 Representing Subroutines Instances, and Post Conditions in SpecDB signed SR Post Conditions table, with the difference that the field Instance number is added, and is part of the key to this table. Also the data in the records indicate the actual runtime post condition behavior after a subroutine is run, as opposed to the designed or the expected, detailed in the Designed SR Post Conditions table.
G. a String of 20 characters. SpecDB allows for user-defined restrictions on types too. 1 List of Valid Values (LOV) In the first kind of type-value restrictions, the values of a variable of a specific type are constrained to only values in a defined list of valid values. e. any variables of the specified type can only take on one of the values in the LOV. For example, the type Month Name can be either January, February, etc. In this case the Has LOV attribute value of the Types entity for the Month Name record is set to T for true and the valid months names are placed in the Types LOV entity, each in a separate record.
