Database Tables
CentreVu®
CMS Open Database Connectivity
Database Items 3-155
Database Items 3
Overview 3
The Database Items descriptions apply specifically to items in the
dbitems
table. The table contains definitions for Dictionary standard
and custom database items, constants, and calculations. The index is
ITEM_NAME. Because the data contained in the
dbitems
table are
administrative, and are used to define dictionary entries, the table is not
dependent on ECS releases.
