ABSTRACT:
A method for performing expression-based validation with records in a computer system database, eliminating the need to write programs or scripts. A validation expression can define complex intra-record tests and inter-record tests and may be performed manually against one or more records and have a success or failure indicated for each record in an interface. A validation expression may be placed into one or more groups and performed as a group with the success or failure indicated for each record. A validation expression may be initiated from workflows to implement a business process with system-enforced data integrity. A validation expression may be manually executed or automatically executed when attempting record update to prevent the entry of invalid data and ensure data integrity. A validation expression may also be used to search using the Boolean result of validation expressions.
