A friend of mine asked them to write a whole dissertation for him and he said it turned out great!
I'm just feeling my way here in the dark.
Use real-world scenarios to drive understanding of the domain and simple models to capture the basics, and note the problems and pain points as you go. A "Trainer" is a Person, and a "WeightLifter" is an Person. Khan Academy is a 501(c)(3) nonprofit organization. I think I see what you are saying - I am just still not at that ah-ha moment.
•Use a conceptual class category list Make a list of all candidate conceptual classes •Identify noun phrases Identify nouns and phrases in textual descriptions of a domain ( use cases, or other documents) 4 0 obj I don't know enough about the action/symmetry/plane, but if there's any other relationship between them, you may even be able to create a movement object as well and have a joint be composed of multiple movement objects.I think what you are describing points out exactly where a HUGE road block for me comes up. 1 0 obj Many of my applications are very data-centric, and I think this is part of the reason it has taken me so long to make the OOP push; it never felt all that relevant.

Any and all feedback would be greatly appreciated.I'm pretty new to this too (just kinda got dropped into OOP programming at my new job), but it seems like you're heading in the right direction, and I'm sure you'll be changing things along the way :)I think the project can still be used to demonstrate OO principles if you scale it up.Let's say the exercise list can be shared between "Trainers" and "WeightLifters."
In my head, I am so familiar with the database tables themselves that I see one object as the relationship between the other tables.

This is often referred to as the "bandwidth" between the teams. Yes, code is another kind of modeling language; it just happens to be executable. Like, I would never create a Joint object since all I ever care about is the joint ID / name. Walk through proposed solutions the same way, refining your mutual understanding of the terms and issues as you go while evolving the common language and identifying relevant subdomains.
From looking at "add/edit" on the live demo, each exercise has multiple joints which has movement, plane, and symmetry, so wouldn't you set up your objects something likeexercise would then be composed of joint[] (which would have everything about each joint returned in separate joint objects).joint would then be what you're calling your ExerciseJointRelationship, but you'd remove the exerciseID (as the joint doesn't need to know what exercise it is being used in, just that it has action, symmetry, plane, and which joint name it is)If you keep joint as a separate object, it can live happily along not knowing anything about the exercise object, but the exercise object would know that it was composed of joints, and would call the joint gateway to add to its joint object array.
