Question

Quizplus · Accepted Answer

A logical data model is an abstract representation of a database's contents that describes the data and the relationships among the data. It is used to define the structure of the database and is typically created before the physical database is implemented. A schema is a blueprint that defines how the data will be organized in the database at a physical level. A physical view is a representation of the database as it is actually implemented on a storage medium. A data dictionary is a centralized repository of information about the data in a database that is used to manage and maintain the database. While all these options are related to databases, the best choice for an abstract representation of a database's contents is the logical data model.
