The proper implementation of a database is essential to the success of the data performance functions of an organization.
Identify and evaluate at least three considerations that one must plan for when designing a database.

Sample Answer
Three essential considerations for planning a database design are data normalization, security, and scalability.
Data Normalization: Normalization is the process of organizing the columns and tables of a relational database to minimize data redundancy and dependency. It involves a series of rules, known as normal forms (1NF, 2NF, 3NF, etc.), that help structure the data logically.
Evaluation: A properly normalized database ensures data integrity by reducing the risk of update, insertion, and deletion anomalies. For example, in a non-normalized table containing student and course information, deleting a student's record might inadvertently delete a course's details if they were stored in the same row. Normalization prevents this by separating the entities into different tables (e.g., a Students table and a Courses table) and linking them with foreign keys. The trade-off for high
