A network database consists of collection of records, which are connected to each other by links. Record : A record is a collection of attributes, each contain only one data value. Link : A link is an association between two records. So, network model is a collection of graphs. Operations on Network Data Model The basic operations that can be performed on network data model are insertion, deletion, updation and retrieval. All these operations are discussed briefly: 1. Insertion : The insert operation is used to insert a new record into the database. 2. Deletion : The deletion operation is used to delete a record from the database. 3. Updation : Since the record appears only once in the network model so changes made to any attributes or columns of the record can be performed easily without any inconsistency. 4. Retrieval : The process of searching and fetching of a record in the database is known as retrieval of a record. Unlike the hierarchical model, the retrieval operation in network data model is symmetric but complex.
