1. A networked computer system comprising: a registration computer system having a registration processor and registration memory having a registration database stored therein, the registration computer system configured to generate unique system identifications; a first computer system having a first processor and a first memory having a first database stored therein, the first computer system receiving a first network-unique system identification generated by and received from the registration computer system; a second computer system having a second processor and a second memory having a second database stored therein, the second computer system receiving a second network-unique system identification generated by and received from the registration computer system; wherein the first and second databases each have installed therein a set of standard tables that are common to both the first and second databases, the set of standard tables being configured to store one or more database records; each database record generated by the first database and stored in the set of standard tables of the first database is uniquely identified by a primary key including: the first network-unique system identification received from the registration computer system, a system-unique identification of one table of the set of standard tables in the first database, and a table-unique identification of a row of the one table of the set of standard tables in the first database; and each database record generated by the second database and stored in the set of standard tables of the second database is uniquely identified by a primary key including: the second network-unique system identification received from the registration computer system, a system-unique identification of one table of the set of standard tables in the second database, and a table-unique identification of a row of the one table of the set of standard tables in the second database.
