How to store the position of a point in the database in this particular case?

Question

MySQL

Hello colleagues.
There is little need to design the storage of a field point in a database - for example the current mouse position.
A field is, roughly speaking, a screen (the whole one) divided into equal squares (for ease of understanding, imagine that your screen is divided by a grid into squares centimeter by centimeter). I see it like this: I store 2 values ​​- the X-coordinates and the Y-coordinates. There are no problems with this, it's like a game of sea battle (if anyone remembers such a game).
BUT :)
The problem starts when I have the Nth number of such screens, for example 100, it turns out that I need to store already 3 numbers, [screen number | field] , [X-coordinates], [Y-coordinates]
And the most important question: if I need to store a lot of such points (I draw your attention to the fact that only realtime numbers are needed, no storage history is needed), in general, if I have a lot of such points, where can I store a bunch of my points (consisting of 3 numbers)? For example, I need to store a thousand such points in real time.
Sql/nosql what advice will be?

Answer 1

You can store 100 x 3 int even in a text file, a more or less modern (not older than 2000 year of birth) computer will cope with their processing without any effort.
Now, if there can be 100 million points of commercials - then you need to think about the storage format. Though sql will pull, with indexes on screens it will be normal.
