Entity Relationship vs Semantic Object Model
Entity-Relationship vs. Semantic Object Model Before we discuss why Entity-Relationship is used more often than Semantic Object model, I would like to introduce you to both of them. According to the University of Texas at Austin’s web site the first model views everything as entities and relationships. But what is an entity? Simon Frazer University’s web site describes entity as an object that exists and is distinguishable from other objects. ... The Relationship is association between two or more entities, for example teacher has to have a student, student has to take some classes. Our first internet source also reveals that the main component of this model is a diagram that visualizes data objects. IT individuals prefer the Entity-Relationship because of its easiness to understand; the data can easily be transferred into relational table, and can be used as a design plan for Database Management Software.
