FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Is a relatively simple representation, usually graphical, of more abstraction of a more complex real-world object event, a data model represents data structures and their characteristics, relations, constraints, transformations, and, other constructs with purpose of supporting a specific problem domain .

Detailed explanation-2: -Representation of data structure in memory is known as Abstract Data Type. Abstract data types can be a list, stack, or queue which will be used to represent different data structures in memory.

Detailed explanation-3: -Data Models. 2 The Importance of Data Models Data models –Relatively simple representations, usually graphical, of complex real-world data structures.

Detailed explanation-4: -A data model is a relatively simple representation, usually, graphical in nature, of more complex real-world data structures. In general terms, a model is an abstraction of a more complex real-world object or event.

Detailed explanation-5: -A Data Model is the relatively simple representation, usually graphical, of complex real-world data structures. This is also known as the Database Model.
