The Automated Data Delivery Systems (ADDS) are two delivery systems designed to either deliver specific data to customer computers over a network such as the Internet or from one application program to another application program. In both cases the user computer requesting data delivery can either have an automatic data reception capability or receive the data without screening the incoming data. In particular, ADDS are systems that allow data delivery services to be offered on the Internet or an Intranet between two Internet/Intranet sites (I2I) or a data delivery service to be offered between an Internet site and a User Computer (I2U). In addition the ADDS invention includes a modification to existing or future application programs that allow the program to deliver 1) specified data 2) in the format specified by the user 3) to the location specified by the user, and 4) at a schedule specified by the user.
