Actually, the network database model was a progression from the Hierarchical database and was designed to solve some of that model's problems, specifically the impossibility of creating a many-to-many connection.Features of a Network Model. 1. Multiple Paths. There may be several paths to the same record due to the increased number of relationships. It allows for quick and easy data access. 2. The Ability to Merge More Relationships. Data is more connected in this model since there are more relationships. This paradigm can handle many-to-many as well ...

The network model was evolved to specifically handle non-hierarchical relationships. As shown below data can belong to more than one parent. Note that there are lateral connections as well as top-down connections. A network structure thus allows 1:1 (one: one), l: M (one: many), M: M (many: many) relationships among entities.Moderated Network Models.
