unit 4 - relational database development
Master the power of data! Learn to design, build, and test relational databases to solve real-world business problems in Unit 4.
Every app you use, every website you scroll through, and every major global business relies on one invisible powerhouse: data. In this unit, you are going to learn how to tame data chaos and build the robust back-end systems that keep the modern world running seamlessly.
We will start by decoding the strict rules of normalisation and designing intricate Entity Relationship Diagrams, essentially drawing the master blueprint for your digital vault. But we will not just stick to the theory - you will get hands-on with industry-standard Structured Query Language (SQL) to construct, query, and manipulate your own tables from the ground up. By the end of our journey, you will have designed intuitive user interfaces, written automated tasks, and rigorously tested your system to deliver a lightning-fast, perfectly optimised database solution ready for any real-world client!
