33
Q

Feature Dataset

A

Collection of related feature classes that share a common coordinate system. Used to spatially or thematically integrate related feature classes.

34
Q

Feature Classes

A

Homogenous collections of common features,e ach having the same spatial representation, such as points, lines, or polygons; and a common set of attribute columns (ie a line feature class for representing road centerlines). Four most commonly used feature classes are points, lines, polygons, and annotation.

35
Q

Relationship Classes

A

Integration of information about various types of geographic and non-geographic (table) entities, many of which can be related to each other.

36
Q

Domains

A

Rules that describe the legal values of a field type, providing a method for enforcing data integrity (like a data dictionary)

37
Q

Spatial Relationships and Rules
