The translation of data from one format to another. ArcInfo supports data conversion from many geographic data formats such as DLG, TIGER, DXF, and DEM.
A frame that displays layers occupying the same geographic area or map. You may include multiple data frames on your map, depending on how you want to organize your data. For example, you may want to include one data frame with only underground conduits and another frame with the rest of your electric network.
Maintenance of data values according to data model and data type. For example, to maintain integrity, numeric columns will not accept alphabetic data. See referential integrity.
1. The result of the conceptual design process. A generalized, user-defined view of the data related to applications. 2. A formal method of describing the behavior of real-world entities. A fully developed data model specifies entity classes, relationships between entities, integrity rules, and operations on the entities. 3. ArcInfo coverages and grids use a georelational data model, which is a hybrid data model that combines spatial data (in coverages or grids) and attribute data (in tables). Other data models used in ArcInfo include TINs, images, and GRIDs.
The characteristic of columns and variables that defines what types of data values they can store. Examples include character, floating point, and integer.
This is the view in ArcMap in which you will create, edit, or update your data, create or update symbology, set suppression scales, control layer visibility, etc.
A logical collection of interrelated information managed and stored as a unit, usually on some form of mass-storage system such as magnetic tape or disk. A GIS database includes data about the spatial location and shape of geographic features recorded as points, lines, areas, pixels, grid cells, or tins, as well as their attributes.
The formal process of analyzing facts about the real world into a structured database model. Database design is characterized by the following phases: requirement analysis, logical design, and physical design.
Database Management System (DBMS)
A set of computer programs for organizing the information in a database. A DBMS supports the structuring of the database in a standard format and provides tools for data input, verification, storage, retrieval, query, and manipulation.
A named collection of logically related data items arranged in a prescribed manner.
The collection and configuration of CUs in ArcMap that represents proposed facilities to be constructed in the field.
Design Ruling Span
Because the Actual Ruling Span cannot be determined until the line is staked, the Design Ruling span is assumed, based on experience, and used for field design
A role in Workflow Manager. A user with this role has the ability to create, edit, and submit designs.
The set of values that is valid for an attribute.
Domains (model name and field model name)
A named constraint in the database. A domain is used to constrain the values allowed in any particular attribute for a table, feature class, or subtype. A domain can be shared across feature classes and tables in a geodatabase. In ArcMap, ArcFM domains are divided in the Model Name Domains and Field Model Name Domains
In tracing, downstream is the direction along the arcs that is the same as the direction of flow. Direction of flow is determined by a user-defined convention.
