TAILIEUCHUNG - Database System Concepts and Architecture

Data Model: A set of concepts to describe the structure of a database, and certain constraints that the database should obey. Data Model Operations: Operations for specifying database retrievals and updates by referring to the concepts of the data model. Operations on the data model may include basic operations and user-defined operations. | Database System Concepts and Architecture Data Models Data Model: A set of concepts to describe the structure of a database, and certain constraints that the database should obey. Data Model Operations: Operations for specifying database retrievals and updates by referring to the concepts of the data model. Operations on the data model may include basic operations and user-defined operations. Categories of data models Conceptual (high-level, semantic) data models: Provide concepts that are close to the way many users perceive data. (Also called entity-based or object-based data models.) Physical (low-level, internal) data models: Provide concepts that describe details of how data is stored in the computer. Implementation (representational) data models: Provide concepts that fall between the above two, balancing user views with some computer storage details. History of Data Models Relational Model: proposed in 1970 by . Codd (IBM), first commercial system in 1981-82. Now in several
