| 1. What is an ER diagram and how is it used in database management? |  |
Ans. An ER diagram, or Entity-Relationship diagram, is a visual representation of the relationships between entities in a database. It helps in designing and understanding the structure of a database by illustrating the entities, attributes, and relationships between them.
| 2. What is the significance of using Cassandra for managing a hotel database? | |
Ans. Cassandra is a highly scalable and distributed database management system that is well-suited for handling large amounts of data. It allows for high availability and fault tolerance, making it an ideal choice for managing a hotel database where data consistency and reliability are crucial.
| 3. How does Cassandra handle data replication and fault tolerance in a hotel database management system? | |
Ans. Cassandra uses a distributed architecture that allows for data replication across multiple nodes. This ensures that even if a node fails, the data can still be accessed from other replicas. It also supports automatic data repair and recovery mechanisms, ensuring fault tolerance and data consistency.
| 4. Can an ER diagram be directly implemented in Cassandra for hotel database management? | |
Ans. While an ER diagram provides a conceptual understanding of the database structure, it cannot be directly implemented in Cassandra as it is a NoSQL database. However, the ER diagram can be used as a reference to design the schema and define the tables and relationships in Cassandra.
| 5. How can a hotel database management system benefit from using Cassandra's flexible data model? | |
Ans. Cassandra's flexible data model allows for dynamic schema changes, making it easier to adapt to changing business requirements in a hotel database. It also supports fast read and write operations, enabling real-time data processing and analysis, which can be valuable for improving customer experiences and optimizing hotel operations.
