Who is this Document for ?

This material is specifically designed for WGU C170 students who need to demonstrate proficiency in relational database design. It benefits individuals preparing for competency-based exams where a deep understanding of normalisation theory is required. Tutors and self-directed learners will also find value in its structured explanation of complex data dependencies.

What you will learn ?
⬤Apply the principles of first normal form to ensure all attributes contain atomic values, thereby eliminating ambiguity in data storage structures.
⬤Identify and remove repeating groups from relational tables to establish a proper foundation for normalized database design.
⬤Understand functional dependencies to determine how non-key attributes relate to candidate keys within relation schemas.
⬤Transform unstructured or partially structured data into well-organised relational databases that adhere to standard normalisation rules.
⬤Recognise common student errors related to second normal form violations and apply corrective strategies to avoid exam resits.
