    1. COthank you for your immediate response. As I mentioned before I want to display my GPS co-ordinates on a Map. To do that should I create a Web Service of my own or is there already a web service which can take my GPS co-ordinates and display it on a Map. I have my GPS co-ordinates in my hand It would be really of great help if you could give me some idea how to proceed from here afterwards.

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).
