JavaCard OS

As far as i know, there is no hash table on smart card.
But now i want to store a hash table containing the terminal configuration.
I guess, smart card only stores the configuration , and the terminal sends the instruction to get stored configuration via APDU commands.
Am i right ? If yes, how can i do this ?
Does anyone work on this ?

Yes,you are right. The smart card only stores the configuration, and the terminal sends the instruction to get stored configuration or update it via APDU commands.

For this goal, you should create your own java card applet. And the applet should process at least three APDUs:
-- Get list of terminal configurations.
-- Update a record of terminal configuration.
-- Delete a record of terminal configuration.

Of course, you should also implement your own data structure.
