Design a Relational Database

Design a Relational Database is a technical skill that opens real doors once you have it. This 90-minute plan is ideal for learners with some foundation — you can complete it from the comfort of home with the materials listed above, no special background required. The goal is not to leave you with theoretical knowledge but with a tangible, lived experience: by the end of this session, you will a properly structured database for a real application or business problem. That concrete outcome is what separates structured plans from casual self-study — you always know what you're working toward and whether you've arrived.

The session moves through 5 carefully ordered steps, covering understand normalization, define entities, create er diagram, and implement database. Each block has a specific time window so you know exactly how long to spend before moving on. The sequencing is intentional: early steps build foundational awareness and muscle memory, while later steps apply those fundamentals under slightly more demanding conditions — the same way a skilled instructor would structure a first lesson. By the time you reach the final step, you will have touched every core element of design a relational database at least once.

One thing most beginners miss: Think about queries before designing. Avoid unnecessary joins. Use meaningful names. Keeping that in mind throughout the session will dramatically improve your results. After this 90-minute foundation session, you'll have a clear picture of which aspects of databases feel natural and which need more deliberate practice. That self-knowledge is the most valuable thing you take away — it turns a one-off session into the start of a genuine learning path.
