Types of database management systems

Hierarchical database

 In a hierarchical database management system, the relationships among data in the database are established in such a way that one data item is present as the subordinate of another one or a subunit. This system is ideal for storing data with items describing attributes, features and so on. One of the key advantages of relying on a hierarchical database is that it can be accessed and updated rapidly. This is so because here the model structure is like a tree and the relationships between records are defined in advance. On the flip side, a major drawback of this system is that adding a new field or record requires the entire database to be redefined.
