Comparative Analysis of DBMS and RDBMS

1: Data Model

 DBMS supports various data models, such as hierarchical and network models, while RDBMS strictly adheres to the relational data model.

2: Flexibility

DBMS offers more flexibility in data storage and retrieval, whereas RDBMS provides less flexibility due to a structured schema suited for clearly defined data requirements.

3: Normalization

 DBMS may not always enforce normalization rules, while RDBMS is designed to enforce normalization, ensuring data integrity.

4: Scalability

DBMS is generally less scalable, particularly for large datasets and complex relationships, in contrast to RDBMS, which is generally more scalable, making it suitable for handling large datasets and complex relationships.

5: Query Language

DBMS supports a data manipulation language (DML) for basic operations, whereas RDBMS utilizes a powerful and standardized query language SQL (Structured Query Language), supporting complex queries and transactions.
