The 'objects' involved are abstractions of real-world entities.Objects are grouped in class hierarchies, and have associated features.IMPORTANCE OF ______ MODEL 1.Data modeling help establish standard data definitions and internal data standards, often in connection with governance. 5 Object-oriented databases can incorporate tables, but can also support more complex data relationships.This approach is employed in multimedia and hypertext databases as well as other use cases People also call these types of diagrams ER diagrams and Entity Relationship Models.An ERD visualizes the relationships between entities like people, things, or concepts in a database. 5.Relational Model The relational model views a database as a set of tables with columns and rows.Each table represents an entity or a data source.Each row is an instance of that entity.ERD Components Keys uniquely identify such rows.And each column is the attribute or property of the entity. 1.Entity ACID Person, Place, Thing, or event that we want to store information about. Denoted by a NOUN. Represented by a rectangle shape in the ERD.Atomicity - Atomic transactions in a ______ setting mean the entire process must finish, or else the file, document, transaction or database reverts to its prior state. 2.Relationship describes the relationship between two entities. denoted by a VERB (passive or active) represented by a diamond shape In the ERD.
