Data Model Top-Level Classes

In the Data Model Browser, the Data Model content is arranged in a tree-type structure. There are ten top-level classes (or branches) of the tree. On the Data Model Browser screen, the list on the left of the allows the user to “drill down” into the subclasses that are below each top-level class.

Association	Functional associations among individuals, organizations, events, and programs.
Education Leadership Artifact	Artifacts are related to the leadership of teaching and learning processes.
Event	The Event entities represent any event within the education organization.
Information Exchange	The Information Exchange entities represent information being communicated.
Instruction Artifact	These entities represent any piece of information related to a student’s learning or the general learning process.
Operations Artifact	These entities relate to the administrative or operational side of the organization.
Organization	These entities represent the grouping of resources and people in order to reach a particular goal.
Person	Individuals within the education setting.
Place	These entities represent the locality or area within the education environment.
Program	A plan of activities and procedures to accomplish a set of objectives.
x_Extensions	This class is not a regular part of the Data Model. It is a category that contains extensions to the Data Model. For example, the category could hold Education Data Exchange Network (EDEN) input file definitions or fact table definitions for a data warehouse. This category allows concepts that are not allowed in the Data Model, such as aggregate statistics or report definitions, to be linked to entities and relationships in the Data Model.
