ABSTRACT:
A method for generating properly formed expressions used as validation expressions and search filters for computer system database applications. One or more embodiments of the invention for example comprise an interface that assists users through the use of automatic tokenizing and/or pick lists of field names and fields values, including a measurement builder for entering legal tokenized measurement values with applicable units of measure. Embodiments of the invention allow knowledgeable users to rapidly create expressions to ensure that the legal syntax and semantics of an expression are not violated while providing the user with pick lists and measurement values within legal ranges and with applicable units of measure. Validations rules are generated and performed on desired records in a computer system database without requiring programs, scripts or queries to be written. A validation expression returns a Boolean result that signifies a success or failure result and may be performed manually or automatically.
