Example for Question 1 (500 words): Explain the differences between hierarchical and relational database models with suitable examples. Discuss the advantages of the relational model in modern applications. Solution:
- Hierarchical Model: Tree-like structure (1:M relationships), e.g., IBM’s IMS. Limitations: Rigid schema, poor query flexibility.
- Relational Model: Tabular structure (Codd’s rules), e.g., Oracle, MySQL. Advantages: ACID compliance, SQL support, scalability.
- Modern Applications: Relational models dominate due to normalization, join operations, and third-normal form (3NF) compliance.
