Q & A

  • What is the primary purpose of designing a database?

    -Databases are designed for specific purposes, such as supporting e-commerce sites, accounting applications, or tracking systems.

  • How does the intended purpose influence database design?

    -The purpose determines the components and elements of the design, affecting how the database will function and what it will support.

  • What are some examples of systems that may require a database?

    -Examples include e-commerce platforms, accounting software, scheduling systems, and automation tools.

  • What key factors should be considered when designing a database?

    -Considerations include data storage, retrieval, processing transactions, and ensuring data consistency and redundancy.

  • What are database transactions, and why are they important?

    -Database transactions are sequences of operations performed as a single logical unit of work. They are crucial for maintaining data integrity and consistency.

  • How do transactions affect database design?

    -Transactions influence how data is stored, saved, manipulated, retrieved, and processed, and impact the overall design and functionality of the database.

  • What is meant by 'data consistency' in a database?

    -Data consistency refers to the accuracy and reliability of data across the database, ensuring that all data remains in a valid state.

  • What role does redundancy play in database design?

    -Redundancy in database design helps to prevent data loss and ensures that there are backup copies of important information.

  • What types of transactions will be discussed in the module?

    -The module will cover BASE, ACID, and possibly other types of database transactions.

  • Why is it important to understand different transaction types in database design?

    -Understanding transaction types helps in designing databases that can efficiently handle data operations while ensuring integrity and performance.
