METHOD AND SYSTEM FOR PERIODICALLY UPDATING DATA RECORDS HAVING AN EXPIRY TIME

A method and system for information delivery of a computer system. The method includes the steps of storing a first data including a program and potentially reusable data on a storage medium of a computer system. In turn, a second data including control data is subsequently stored on the same storage medium as the first data. The contents of the control data is unknown at the time the first data was stored. The control data corresponds to a subset of the potentially reusable data. The program is executed and combines the control data and the potentially reusable data to create on the storage medium of the computer system a third data including newly indexed available information. Information is delivered by sending a plurality of transmissions where known data is sent in advance to minimize the subsequent delivery of unknown control data that becomes known based upon a future event.
