  2. Object-Oriented Database Management Systems (OODBMS): Designed for complex data models, OODBMS stores objects as entities in databases rather than using traditional table structures. This type allows storing and retrieving complex data structures directly without mapping them to relational models. Some popular examples include MongoDB, Apache Cassandra.

  3. Hierarchical Database Management Systems (HDBMS): As the name suggests, these systems arrange data hierarchically using parent-child relationships. Each child can only have one parent but multiple children may share a common parent node. HDBMS is commonly used in mainframe environments due to its simplicity and efficiency in handling hierarchical data structures.

  4. Network Database Management Systems (NDBMS): Similar to HDBMS, NDBMS also organizes data using relationships but offers more flexibility by allowing each record to have multiple parents or owners. It enables developers to create complex relationships among records easily.

The table below summarizes the characteristics of these database management system types:

Type Key Features
RDBMS – Tabular structure- Data integrity enforcement
OODBMS – Complex object storage- Support for inheritance
HDBMS – Hierarchical data organization- Simplicity
NDBMS – Flexible relationships among records

Understanding the different types of DBMSs is crucial in selecting the most suitable one based on specific business needs. In the subsequent section, we will delve into the key features that make a DBMS an essential tool for efficient data management and retrieval.
