feature class

[data architecture] A collection of geographic features with the same geometry type (such as point, line, or polygon), the same attributes, and the same spatial reference. Feature classes can be used to group homogeneous features into a single unit for storage purposes. For example, highways, primary roads, and secondary roads can be grouped into a line feature class named roads. In a geodatabase, feature classes can also store annotation and dimensions.
