File-based vs Relational database - A Level Computer Science 9618
Показать описание
In this video, the limitations of file-based approach are discussed, including program-data dependence, data inconsistency, and difficulty performing complex searches. The advantages of a relational database approach are also explained, including reduced data redundancy, program data independence, the ability to provide different views, and improved data integrity. The video ends with a past year question discussing why a file-based approach is not better than a relational database.
Whether you're a student preparing for the Cambridge International AS & A Level Computer Science 9618 Paper 1 exam on Chapter 8: Databases or a professional seeking to broaden your knowledge, this video is ideal for you.
