Posted by
Hierarchical Model
The hierarchical model arranges records in hierarchy like an organizational chart. Each record type in this model is called a node or segment. A node represents a particular entity. The top-most node is called root. Each is a subordinate of the node that is at the next higher level. A higher level node is called parent and lower level node is called child. A parent node can have only one parent node. This kind of structure is often called inverted tree.
Network Model
The network model is similar to hierarchical model. The difference is that child nodes. The child nodes are represented by arrows in network model. It requires more complex diagram to represent a database. It also provides more complexity than hierarchical model.

Relationship Model
Relationship model is the most commonly used database model. It is more flexible than hierarchical than database models. The relational model consists of simple relations. A relation is a term used for table. A relation represents a particular entity. It is used to store Information about the entity. The relationships are based on the data of entities.
