Hi Class,

The project has been released under the “Project” section. The deadline for the project is 16:59:59 Mon July 13th (Sydney Time) .

Tips:

• Familiarise yourself with the project database first. Before attempting the queries straight away, try to examine what each relation holds and find out how relations might be related to each other.
• Set up the project database ASAP so the tutors can assist you with any related issues.
• Make sure that your solution can load and run correctly. You can check your answers using check.sql.

Dear Students,

Welcome to Database Systems!

We’re excited to have you join this course and look forward to exploring the foundations and real-world applications of modern database systems together.

Data is at the core of almost every modern application, from social media and e-commerce platforms to banking systems, healthcare, cloud services, and AI applications. Understanding how data is stored, managed, queried, and processed efficiently is an essential skill for computer scientists and engineers.

This course combines both theoretical foundations and practical hands-on skills. You will not only learn how databases work internally, but also gain experience designing and implementing database applications using industry-relevant technologies.

We encourage you to actively participate in lectures and labs, ask questions whenever you are unsure, and practice consistently throughout the term. Database concepts often build upon each other, so keeping up with weekly materials will help you get the most out of the course.

Most importantly, we hope you enjoy the learning journey and develop a strong foundation in database systems that will be valuable in your future studies, projects, and careers.

Looking forward to a great term with all of you !

Wenjie
