Question

I’m trying to create a JSON object file and I’m not sure how to document a list of all skating classes available. Currently I have the following:

[
{"classname":"FS1","classdays":["monday", "wednesday"]},
{"classname":"FS2","classdays":  ["tuesday", "thursday"]}
]

It works, the only problem is that each class “classname”, has multiple classtimes for each day “classdays”. And I’m not sure how to add another array of times and associate them with the specific day for the specific classes and add that to my current JSON file to create that structure.

Here are the classes in non-programming language – for clarity:

Classname: FS1
Monday classes are 12:00PM and 2:00PM
Wednesday classes are 1:00PM and 3:00PM
Classname: FS2
Tuesday classes are 4:00PM and 6:00PM
Thursday classes are 2:00PM and 8:00PM
Classname: FS3
Monday classes are 2:00PM and 4:00PM
Thursday classes are 2:00PM and 8:00PM

I’m open to suggestions on how best to structure, or restructure if needed.

Answer 1

First, just to point out JSON is not a “programming language” it’s a data language. The difference being JSON, like XML doesn’t do anything it just describes objects.

Second, I think the direction you’re heading in is going to run you squarely into the realization that JSON is not relational.

Finally, here’s how I would do it:

[
    { "classname":"FS1",
      "classdays":[
        { "classday":"Monday",
          "classtimes": ["12:00 PM", "2:00 PM"]
        }, 
        { "classday":"Wednesday",
          "classtimes": ["1:00 PM", "3:00 PM"]
        }
        ]
    },
    { "classname":"FS2",
      "classdays":[
        { "classday":"Tuesday",
          "classtimes": ["4:00 PM", "6:00 PM"]
        }, 
        { "classday":"Thursday",
          "classtimes": ["2:00 PM", "8:00 PM"]
        }
        ]
    },
    ... And so on.
