Computer-aided design. An automated system for the design, drafting, and display of graphically oriented information.


Cardinality describes how many objects of type A are associated to how many objects of type B.


The vertical dimension of a table. A column has a name and data type applied to all values in the column.

Compatible Unit

A Compatible Unit (CU) is a field within a table that contains the model name of a specific device, piece of equipment or other feature in your utility network. CUs differ from features in that they are the building blocks of a design and contain WMS-specific information. Each CU consists of two levels. The primary, or parent, level contains the feature's attributes such as material and object ID. The secondary, or child, level contains WMS-specific information such as Work Function.


The state that indicates a work request has traveled through the entire work request process flow. Only users with the Administrator role may view Completed work requests.

Complex Edge

In a geodatabase, a linear network feature that corresponds to one or more network elements in the logical network.

Composite Favorite

A composite favorite allows you to store and easily recall a set of frequently-used features, such as a switchgear cabinet. A composite favorite must contain at least one point feature.

Connectivity Rules

In a geodatabase, network rules constrain the type of network features that may be connected to one another, and the number of features of any particular type that can be connected to features of another type. In most networks, not all edge types can logically connect to all junction types. Similarly, not all edge types can logically connect to all other edge types through all junction types. There are two types of connectivity rules: edge-junction and edge-edge.

Contingent Attribute Validity

A set of valid values that depend on the value of another attribute.


A set of numbers that designate a location in a given reference system, such as x, y in a planar coordinate system or an x, y, z in a three-dimensional coordinate system. Coordinates represent locations on the Earth's surface relative to other locations.


1. A digital version of a map forming the basic unit of vector data storage in ArcInfo. A coverage stores geographic features as primary features (such as arcs, nodes, polygons, and label points) and secondary features (such as tics, map extent, links, and annotation). Associated feature attribute tables describe and store attributes of the geographic features. 2. A set of thematically associated data considered as a unit. A coverage usually represents a single theme such as soils, streams, roads, or land use.

CU-Defining Attributes

CU-defining attributes designate the features of that specific Compatible Unit, a pole's height and class, for example. CU-defining values are non-editable and displayed as grey on the Attribute Editor.

Current Owner

A field in Session Manager and Workflow Manager. The user listed in this field is the person currently responsible for the session, design, or work request. The value (or name) in this field may change when the session, design, or work request is transition to another state.

Custom Field Editors

Custom Field Editors allow the implementation/customization programmers to write specialized field editors that are specific to their needs. Those custom field editors extend the functionality of the ArcFM Attribute Editor by allowing developers to create custom fields such as tabs, forms, and date/time pickers. See ArcFM Application Developer's Guide.

Custom Text Elements

Custom Text Elements allow you to insert text elements such as page numbering and dates into your map set. ArcFM offers several sample text elements or you may develop your own. See ArcFM Application Developer's Guide.
