The Custom data page allows you to view, edit, create and delete database records: to select a table simply click the corresponding button
When we click on one of the tables, for e.g Nccm_parameters shown below, we can view the records in that table.
As we type away into the search box on top right, the tables matching the text are displayed. For e.g if we type dhc, the tables matching dhc are shown
To edit a existing row select the row in question and change the value(s) then click the Save button.
