1.1 What Does LEXICON Do?
LEXICON enables the PDMS system administrator to add new attributes to any element
in the Design, Catalogue and Drafting databases of a project. These User Defined
Attributes (UDAs) are created as elements in the LEXICON database inside the PDMS
project. Because LEXICON databases are project-specific, it is possible to define
attributes to suit individual project requirements or company standards.
Once defined, UDAs may be accessed in much the same way as normal attributes,
including setting values, querying and reporting upon these values. Utilities such as the
Data Output and Project Reconfiguration functions treat UDAs as they would any other
attribute. UDAs can also be used in expressions.
1.2 The LEXICON Database
Before a project can use UDAs, a DICTIONARY database must be created. This is done
by using the ADMIN module in the same way as for any other type of database.
UDAs may be changed or deleted during the course of a project. The dictionary will
contain all the UDA definitions for a project and if data is to be transferred between
PDMS projects the dictionary must be transferred as well. The data output and project
reconfiguration functions can be used to do this.
1.3 Who Should Read This Manual
This Reference Manual assumes that you are familiar with using PDMS at a System
Administrator level. Access to LEXICON is normally restricted to FREE users only.
