Groups of records are stored in a table c. Queries – a request for information from a database. A select query retrieves data. An action query can ask for additional operations on the data, such as updating or deleting information. d. Network Model – a database model that is thought of a flexible way of representing objects and their relationships. It is a database that runs in a server in the network; a database of network user addresses; and a database organization that allows for data relationships in a net-like form.
