Abstract:
A method of comparing data contents contained in user predefined fields of a user predefined database table of a user predefined database at user predefined intervals, the method allowing for one or more of a plurality of actions to be taken, the method comprising the steps of:a) sending a query to said user predefined fields, extracting a first instance number representing the data contents of one or more fields associated with a primary field, wherein said one or more fields used in extracting said first instance number are selectable by a user and wherein said first instance number is a hashed value, and placing said first instance number in a â€œsnapshotâ€  data record; b) at said user predetermined time interval, sending said query to said predefined fields, and extracting a second instance number representing the data contents of said one or more fields associated with said primary field at said user predetermined interval, wherein said second instance number is a hashed value; c) comparing said first instance number with said second instance number, wherein a mismatch between the first instance number and the second instance number indicates the data contents of said one or more fields associated with said primary field have changed over said predetermined intervals; d) applying a business rule to determine which of said plurality of actions to take if a mismatch exists between the first instance number and the second instance number; and, e) performing at least one of said plurality of actions if no mismatch exists between the first instance number and the second instance number.
