Provided we dont have any information to how many submenus it will go on. say suppose, we have this navigation CODE Home Departments --CSE -----Department -----Faculty ---------Mr A ---------Mr B -----Labs -----Library --ECE --Mech --Elect Contact --Admin --Director The above navigation is an example. say suppose if i want to add another submenu under CSE>FACULTY, there is a place for that in the DB. Or if i want to add a submenu under CSE>FACULTY>MR A>m there is also a place for that in the DB. It may go on and on, i may want to add another submenu under CSE?FACULTY>MR A>SUBMENU>SUBMENU....

The application is where you worry out presentation, not the data layer. You can model a navigation map in one simple table: CODE nav_item nav_item_id label url sequence parent_id Here, I've made NULL top level. CODE 1,Home,http://www.foo.com/,100,NULL 2,Departments,,200,NULL 4,CSE,,100,2 10,Department,,100,4 11,Faculty,,200,4 14,Mr A,,100,11 15,Mr B,,200,11 12,Labs,,300,4 13,Library,,400,4 5,ECE,,200,2 6,Mech,,300,2 7,Elect,,400,2 3,Contact,,300,NULL 8,Admin,,100,3 9,Director,,200,2 You want a list of everything under departments? sql select a.nav_item_id, a.label, a.url from nav_item a where a.parent_id=2 order by sequence
