Information about an entity that can be measured, classified, or described.
Class
A set, collection, group, or configuration containing members regarded as having certain attributes or traits in common; a kind or category.
Concept map
Describes the structure of the Data Model. A concept map represents a logical set of relationships among classes, sub-classes, and entities.
Conceptual data model
A model that focuses on the meaning of concepts and the relationships among concepts important to address user needs. A conceptual model is not constrained by any kind of database technology.
Entity
The constructs that need to be tracked, measured, and described by software systems in order support education processes.
Logical data model
A logical data model is a representation of the concepts in the information domain but takes into account the technology that will be used. In most cases today, the technology being used to represent information is a relational database; therefore, logical models often have tables, columns, and foreign key relationships.
OWL
Web Ontology Language (OWL) is an XML language for expressing relationships and is a standard published by the W3C web standards group. The OWL language represents both a taxonomy of entities, as well as multiple types of simultaneous relations among the entities.
Physical data model
A physical data model implements the conceptual data model using a particular technology, such as a relational database. The physical model also takes into account local requirements for the system as well as conventions and requirements of the database software.
Sub-class
A sub-class is a class that is a subcategory of another class; for example, primate is a sub-class of mammal. The sub-class itself can also have sub-classes; for example, chordate is a sub-class of the class primate. In the Data Model, a Staff Member is a sub-class of Service Provider and Service Provider is a sub-class of Person.
