Practice WOD: Warehouse

The goal of this WOD is to get comfortable diagraming using Lucid Charts. Read Chapter 7, Section 1 on the Warehouse model. Also review the Model Design Guidelines.

Instructions

Please construct an ER diagram using Lucid Charts of the Warehouse application described in Chapter 7.

1. Start your timer.
2. Call your chart ERD-Warehouse.
3. Use Lucid Charts and the appropriate crows foot notations.
4. Specify the entity fields in your entity descriptions. Be careful to exclude Java fields that implement relationships.
5. Make sure to follow the model design guidelines.
6. When finished, download a PNG file containing your description.

When finished, stop your timer, and record how many minutes it took you to complete the WOD.

Rx: < 8 min Av: 8-12 min Sd: 12-15 min DNF: 15+ min

Demonstration

Once you’ve finished doing the WOD a single time, watch me do it:

Standard WOD Caveats

You’ll learn significantly less from watching me solve the WOD if you haven’t attempted the WOD yourself first.

While it’s an achievement to finish the WOD no matter how long it takes, you might experience “diminishing returns” if you work longer than the DNF time. Thus, it might be strategic to stop working at the DNF time and watch my solution.

After watching my solution, I recommend that you repeat the WOD if you have not achieved at least Av performance. If so, be sure to:

• Delete your old project so you cannot refer to it;
• Don’t look at my screencast while you WOD; and
• Reset your timer.

Feel free to keep trying until you make Rx if that’s of interest to you.
