A network database is a type of database model that allows for a more flexible relationship between data elements. Unlike traditional hierarchical databases, which organize data in a tree-like structure, network databases use a graph structure, enabling multiple relationships between records. This means that a single record can be linked to multiple other records, making it easier to represent complex data relationships. In a network database, data is stored in records, and these records are connected through links. This structure allows for efficient data retrieval and manipulation, as users can navigate through the interconnected records. Common examples of network database management systems include Integrated Data Store (IDS) and TurboIMAGE.
