object class

See Also: feature class

  1. [ESRI software] In a geodatabase, a collection of nonspatial data of the same type or class. While spatial objects (features) are stored in feature classes in a geodatabase, nonspatial objects are stored in object classes.
  2. [data models] A table in a geodatabase used to store a collection of objects with similar attributes and behavior. Objects with no locational information are stored as rows or records in object classes. Spatial objects, or features, are stored as rows in feature classes, which are a specialized type of object class in which objects have an extra attribute to define their geographic location.
