with the domain. These values must be consistent both
locally and globally with respect to legal values, range, and
data types. In addition to these general verification criteria,
the domain must also meet implementation specific criteria
such as host language reserved words and syntax constraints.
AgPest System uses integer,char and string data types in
rules. Most of the user replies are integer data type based, for
consistency of knowledge base and rule execution we have
implemented a
condition for each user input. This condition tests the user
input for correctness and tests for data type correctness if the
input range is out of given range or input data type itself is
false then automatically that session ends.
