Which Data structure suits

[Uma]

Hi,
I need to fetch data from different tables and form a data structure
which has one key value database name and 3 other fields related to
this key.For example :
Database1,Model-1,19.2.2.2,ID11.
Database2,Model-2,193.13.3.3,ID12
Database3,Model-3,192.2.2.1,ID13

I need to store these in a data structure,Which data structure will be
good for this.I am searching some thing other than structs.
Thanks
Uma.

you can use array of array list, i.e Array will contain array list as
array item.
this will be faster i suppose.
