How to store day time slots that generates weekly

Question

Let's say i have an app with a calendar each day is divided into time-slots, example :

Monday : 8-10h 10-12h 12-14h

Tuesday : 8-10h 10-12h 12-14h

and every time slot has an event and the calender is updated weekly which means that this weeks time slots and events will no longer be available and will be replaced by a new week calender with new time slots events. what's the best way of storing such data?

Answer 1

Assuming you don't care about saving previous weeks time slots.

Depending on your use case, you have 2 option. Either storing in database or in json file.

Option 1:

Since each day have multiple time slots, this is clearly one to many relation ship. Day X has N number of time slots.

So first, create days table like this:

dayID	name
abc123	Monday
abcd1234	Tuesday

Then, create another table for time slots where you have your time slots and the dayID as foreign key, like this:

timeSlotID	fromTime	toTime	dayID
efg123	8	10	abc123
efg1234	10	12	abc123

Option 2:

Now, if you only care about storing next week time slots I think storing this in database is not necessary. You can simply store them in a json file, since your data is really small and json files are fast and easy to deal with no matter what language and framework you are using.

You can store your data in this way:

{
"Monday": [
    {
        "fromTime": 8,
        "toTime": 10
    },
    {
        "fromTime": 10,
        "toTime": 12
    }
],
"Tuesday": [
    {
        "fromTime": 9,
        "toTime": 11
    },
    {
        "fromTime": 12,
        "toTime": 13
    }
]

}

And you can easily recreate the json data each week.
