Class Time
There are no planned activities today, but you are encouraged to stop by MS Teams with any questions between 8 and 10 am Grinnell Time.
I encourage you to practice creating a simple database for your individual project. You can practice creating a new model and SQL database which you can push to Heroku for practice: Simplified Model and Database exercise. This will help you prepare to do Homework 6.
If you have no questions, you should be working with your team to finish the Memo of Understanding and finish organizing your planned roles and work flow for the team project. Make sure you have scheduled meeting with your community partner and your alumni mentors for the next weeks.
Upcoming Assignments
- Memo of Understanding (team) – due today
