Hi i have been working on a online shopping project for gifts .

 

My Navigation menu has 3 Levels like this : 

 Parent Menu ==> Child Menu ==> Child Sub Menu .

i have to get all these values from the database table in a hierarchy, i was thinking to design the database table in such a way that request time for fetching menu data from table is minimal.

 

my idea is to design a table name navigation_menu with following parameters : id(as menu id),Menu_Name,Parent_id

 

id(Parent Menu id)	Menu_Name	Parent_id
0	BIRTHDAY	-
1	OCASSIONS	-
2	GIFTS	-
3	SPECIAL	-
4	CAKES	0
5	OFFERS	1
6	GIFTS	0
7	SPECIAL CAKE	4
8	PHOTO CAKE	4

 

Or can i design the database in a better way to fetch the data more faster (Suggestions required).
