    <p>I am having some troubles trying to implement some methods. That is what I do. </p> <p>1)1 object of class sistema is created with 1 Object of class Rotor and 1 object of class IModeloDinamico inside.

In the first one I made some format mistakes I tryed to fix. But it is probably there are some other errors. My apologize if my message is difficult to read. Tell me what is wrong in format and I will fix it.</p> <p>Thanks a lot for the help!!!!!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
