Question

after getting my answer here:
Database issue, how to store changing data structure

i have another question.

lets say i have a workout:

first set: 60 push ups
second set : 55 push ups
third set: 50 push ups
firth set: 45 push ups
and so on..

I think it would be a waste to make an entry for each set,
but making something like this:

workout_id  tabindex     repeat      quantity     quantity_unit  activity
1           1            3           60,55,50,45  pcs            pushups
1           2            1           2            minutes        rope-jumping

seems primitive.

any suggestions?

Answer 1

You could always put quantity in its own table, then you end up with data that looks like this:

tblWorkouts:
----------------------------
workout id   activity   etc
----------------------------
1            pushups    ...


tblQuantities
------------------------------
qID     workout_id    quantity
------------------------------
1       1             60
2       1             55
3       1             50
4       1             45

The quantities are linked the proper record in the workouts table vai the workout_id – thats the relation in relational database 🙂

This gives you some flexibility in doing things with the data once its in the database. This way its stored as number rather then a comma delimited string you have to parse and add up if you want to get any kind of meaningful data out of it.
