1. A system implemented on a microprocessor-based device for supporting self-expiring data content, comprising:
a user created database, configured to store data records, wherein each data record includes a data portion and an expiration time portion;
wherein said data record expiration time portion is configured to be modifiable by the user of the system to select or change or remove the content of said expiration time portion for each record at any time;
wherein, periodically, the system compares the content of the expiration time portion in groups with a common expiration time to one of a present time or time interval and deletes data records wherein the contents of the expiration time portion indicate an expiration time that is before the present time or exceeds the time interval;
wherein if contents of the expiration time portion are not provided by the user, the system is configured to automatically determine and associate a default expiration time with the data record, and populate the expiration time portion with said default expiration time prior to storing the data record in the database; and
wherein said default expiration time may include no expiration time.
