    1. COIf you do-not have cors enabled of the server a client side script probably won't be able to send request to your service.

    2. CO@AkshatJiwanSharma I do not have Cross-Origin Resource Sharing enabled on the server. So I should not worry that someone can write an utility to call my SignUp webservice URL with bogus data and Login webservice URL with brute force attack on password for any particular userid?

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.

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