Teamcenter Glossary

Below are definitions of various terms relevant to Teamcenter and Product Lifecycle Management (PLM). This document is very much an ongoing work-in-progress. I make every attempt to define the terms correctly, however the definitions are my own. Sometimes I may be wrong and sometimes I may do a poor job of explaining the term. The point is, this is a resource, but it is not authoritative. If you have business-critical decisions to make that hinge on the definitions here, I suggest you get a second, independent, opinion.

2-Tier
One of two possible architectures for Teamcenter client installations. The two tiers are,

  1. Client tier. The user’s local machine
  2. Resource tier. The database and volume data servers.

In a 2-tier configuration there is a server process, tcserver.exe, which runs locally on the user’s machine and communicates directly to the database server. This configuration is only recommended when the client and the server are both on the same LAN.

4-tier
One of two possible architectures for Teamcenter client installations. The four tiers are,

  1. Client tier. This is the user’s local machine
  2. Web tier. This is a web server which routes communications between the client tier and the application server tier
  3. Enterprise tier. This consists of one or more application pool servers which run the Teamcenter server processes.
  4. Resource tier. The database and volume data tiers

Because the Enterprise and Resource tiers are generally co-located with a high-bandwidth, low-latency connection between them, this architecture is preferred for WANs or any time when there is a high latency between the client and the resource tiers.

A

Action Handler
A workflow handler which performs some sort of action. See also, Rule Handler.
Alt Rep
Alternate Representations. In the Unigraphics integration with Teamcenter, alt reps are additional datasets which describe the design described by the UGMASTER dataset. Alt reps are alternate representations of the geometry. A significant limitation with alt reps is that they cannot be assemblies.
Attribute
A persistent property of a business object. Attributes are columns in a database table.

Assembly
Assembly Structure

B

Bill of Materials
A listing of parts and documents which make up a deliverable product. For a CAD model this may be referred to as its assembly structure.
BMIDE
Business Model Integrated Development Environment. A stand-alone program used to define the Teamcenter data model.
Read more:

BOM
See Bill of Materials.
BOM View Revision
The BOM for a specific item revision.
BOM, Imprecise
A BOM structure in which the components are Items, not Item Revisions.
Read more:

BOM, Precise
A BOM structure where each component is an Item Revision.
Read more:

Business Object
Business Object, Primary
A business object which uses its own, dedicated, storage class which has the same name as the business object and which is at the same location in the class hierarchy as the business object is in the business object hierarchy.
Read More:

Business Object, Secondary
A business object which uses the same storage class as one of its ancestor business objects in the type hierarchy.
Read More:

BVR
See BOM View Revision

C

CN
See change notice
Cache Server
CAD BOM
The BOM generated by a CAD tool. Typically the CAD BOM might not contain non-geometric items, such as adhesives and paint, and may contain different representations of the same component, especially when the component is deformable and is shaped to fit in different installations.

Class
See Storage Class
Component
An element of an assembly. May refer to piece-parts, which do not have any components, or sub-assemblies, which do.
CR
See change request

D

Dataset
A workspace object which is an abstraction of a file stored in Teamcenter. A dataset typically contains one or more named references, which may be files stored on the volume server or forms.
Read More:

Dataset Tool
An object that defines which applications, based on MIME type, will open named references in a dataset, based on file type.
Deep Copy Rule
A configuration option for Item Revisions which defines how related objects, such as datasets and BVRs will be handled when a new revision is created. Typical options are to not copy the related object, to add a reference to the existing object under the new revision, or to create a duplicate object under the new revision.

E

EBOM
Engineering BOM. The complete BOM of a Part, which can be used for ordering and building the part. See also, CAD BOM, MBOM.
EDS
Electronic Data Systems. A software services company which used to own the Unigraphics software product.
ER
Enhancement Requests. Placebo pills given out by GTAC when your IR has been declared to be working as designed but you insist that things shouldn’t be designed that way. In theory, ERs may eventually be implemented in the application, although reports of this actually happening are generally considered to be apocryphal.

F

Folder
A workspace object used to collect related objects together. Folders in Teamcenter are similar to folders in Microsoft Windows with one key difference, objects may belong to multiple Teamcenter folders.
Folder, Pseudo
A virtual folder which shows a relationship between the folder’s parent object (usually an item revision) and zero or more objects which are related via a common relationship. The most common of these is the view pseudo-folder which appears underneath item revisions to show the components of the parent revision.
Read More:

Form
An object used to gather and display a certain set of properties. The most commonly seen forms are item and revision master forms, although others may be created and used in a variety of ways.

G

GRM Rule
Short for Generic Relationship Management Rule. GRM Rules define the cardinality (e.g. 1:1, 1:Many, Many:Many) for relationships between different types of objects.

Thin Client
A web-based user interface for Teamcenter. It supports many of the functions of the full-featured rich client, however it does not currently support administrative functions or integrations with other applications.

U

Unit of Measure
An property of items, abbreviated as UOM, which specifies in units in which the item is purchases. When unset the value is assumed to be each, meaning the item is purchased in whole units (2 brackets, 4 screws, etc.). It is not the units in which the item is modeled and dimensioned. Examples of non-Each UOMs are tape, 6.5 inches or adhesive, 0.5 ounces.
