Course Introduction
Database Programming is a comprehensive course that introduces students to the fundamental concepts and practical skills required to design, develop, and manage databases using programming languages. The course covers essential topics such as relational database models, Structured Query Language (SQL), data manipulation, transaction processing, stored procedures, triggers, and integration of databases with application code. Students gain hands-on experience working with popular database management systems and explore best practices in data security, normalization, and optimization. By the end of the course, participants are equipped to build dynamic, data-driven applications and solve real-world problems using database programming techniques.

Q1) Explain why it is better to try to control redundancy rather than eliminate it. Answer: Although eliminating redundancy is the ideal,it is not always possible.Sometimes,for reasons having to do with performance,you might choose to introduce a limited amount of redundancy into a database.However,even in these cases,you would be able to keep the redundancy under tight control,thus obtaining the same advantages.This is why it is better to say that you control redundancy rather than eliminate it.
