Types of RDBMS

Types of Database Models:

• Hierarchical Databases: This model organizes data into a tree-like structure. Each record has a single parent, resembling an organization chart. Navigation is done by moving up and down the tree.
• Network Databases: This model is similar to the hierarchical model but allows each record to have multiple parent and child records, forming a graph-like structure.
• Relational Databases (RDBMS): This model stores data in tables (relations) which are linked to one another using keys. It is the most widely used model due to its flexibility and simplicity. Examples include MySQL, PostgreSQL, and Oracle.
• Object-Oriented Databases: This model stores data in the form of objects, as used in object-oriented programming. The objects have attributes and methods associated with them.
