Database Item IDs |
|||
Accessing a particular entry of the database is normally performed by using its database entry number p (see figure below). However, entry numbers may change during the lifetime of a database (i.e. after deleting one or more entries). Consequently, they must not be used to set up relations between database entries. In order to have a reliable, never-changing and unique key to the data in the database, each new entry automatically receives an item ID (parameter ItemID) which can be used to access a particular database entry even when the entry number has changed.
