Database Types

A Plant project can contain the following types of database:

System Databases

• The SYSTEM database itself, which holds the access control data for the model data and modules.

• The COMMS (Communications) database, which stores information about who is using which module and which model databases are available.

• The MISC database which store inter-user messages, and inter-database macros.

• In a Global project there will also be the Global database and a transaction database.

Model Databases

• The Design database which contains all the design information for the project

• The Catalog database where the project catalog and specifications are stored.

• The PADD database which contains data about drawings produced by Draw.

• The PROPERTIES database which can contain material properties, and can be referenced by the catalog.

• The DICTIONARY database which holds the definitions of user-defined attributes (UDAs), as set up in Lexicon.

• The ISOD database holds spool drawings generated by SPOOL.
