It is a party . The Data Model Most developers who do significant work with the ACS will become intimately familiar with the parties data model, and probably extend it on many occasions. For this reason the parties developer guide will begin with an introduction to the data model. The central table in the parties data model is the parties table itself. Every party has exactly one row in this table.
Every party has an optional unique email address and an optional url.
A party is an acs object, so permissions may granted and revoked on parties and auditing information is stored in the acs objects table. One is the persons table and one is the groups table. A row in the persons table represents the most basic form of individual that is modeled by the parties data model. A row in the groups table represents the most basic form of an aggregation of individuals that is represented. This guarantees that if there is a row in the persons table then there must be a corresponding row in the parties table.
