How to OL Connect DataMapper Array

Hello;
As you can see in the following figure, I need to get the names of all ‘Name’ columns in the table line by line.

Is it possible I can not do this?

This is a trial run, we actually have 200 different variables in the design we need to do. The Backend developer thinks it’s wrong to create a 200-column db model, and he wants to make a table with some of the details back in a single column.

Would you please explain the data structure and the layout needed?

Hello ;

First, the image of the structure I use is as follows.

The example of this structure is as follows;

Corresponding columns

What I am trying to do is to write the above information in a single column with any brackets(, - / \ _ …) and use them in their respective places during the design phase.

We can think of tags as strings.
