WGU D326: Advanced Data Management
D326 pushes past basic SQL into PostgreSQL programmability: you build a business report using user-defined functions, triggers, and stored procedures, then record a video walking through your code. It's a performance assessment course in the BSCS and software tracks.
Fennie is independent and not affiliated with Western Governors University. This is an unofficial study guide.
What makes it hard
The SQL itself is a step up, with functions, triggers, and procedures being new syntax for most students, but the structure trips people more: the PA is one integrated business-report scenario, and submissions bounce when the pieces don't connect or the required video walkthrough skips rubric points.
What you'll cover
- • User-defined functions in SQL
- • Triggers
- • Stored procedures
- • ETL concepts and data transformation
- • Business reporting queries
- • PostgreSQL environment
The D326 study guide
How to study for WGU D326, step by step.
- 1
Read the rubric and design the report first
Pick your business question and sketch how the function, trigger, and procedure connect before writing SQL. The PA is one integrated scenario, and disconnected pieces are the usual return reason.
- 2
Get comfortable in the PostgreSQL environment early
The provided database and tooling have their own quirks. Run simple queries and a throwaway function in the first session so the environment is solved before the real work.
- 3
Build and test each object incrementally
Write the function, verify it, then the trigger, then the procedure, testing each against the data before integrating. Debugging all three at once is the slow path.
- 4
Rehearse the video against the rubric
The recorded walkthrough must hit specific rubric points about how your code works. Outline the video from the rubric and do one practice run before recording.
- 5
Audit and submit with revisions in mind
Check every rubric line, confirm the code runs clean end to end, and submit early. Evaluator feedback on a near-complete attempt is faster than solo perfectionism.

FAQ
Is WGU D326 hard?
Moderate. Functions, triggers, and stored procedures are new syntax for most students, and the PA requires them to work together in one business report. Incremental building and testing keeps it manageable.
What do you submit for D326?
A written business report built on PostgreSQL code (including a user-defined function, trigger, and stored procedure) plus a recorded video walking through how your SQL works.
How long does D326 take?
Typically 2-4 weeks. Students who design the whole report before writing SQL avoid the rework that stretches it longer.
More WGU courses
C959: Discrete Mathematics I
C959 introduces logic, set theory, functions, relations, and proof techniques, the math backbone of WGU's computer science degree. It ends in an OA and is widely treated as the first real difficulty checkpoint in the BSCS.
C960: Discrete Mathematics II
C960 continues from C959 into counting, probability, graph theory, trees, recursion, and algorithm analysis concepts. It ends in an OA and rounds out the discrete math requirement for the BSCS.
C949: Data Structures and Algorithms I
C949 covers core data structures (arrays, lists, stacks, queues, trees, hash tables) plus searching, sorting, and Big-O analysis, with examples in Python. It ends in an OA and is a pillar course in WGU's computer science and software degrees.
C950: Data Structures and Algorithms II
C950 is the project course that follows C949: you build the well-known WGUPS package-routing program in Python, applying hash tables and a routing heuristic to deliver packages under constraints. It's assessed as a performance assessment (PA): code plus a written analysis, not an exam.
