Build 3 dimensional Dictionary




Could anyone help me to understand how 3 dimensional dictionary needs to be initialized and defined.

A 3D dictionary would be like:
Name keyA keyB keyC
key1 value1A value1B value1C
key2 value2A value2B value2C
key3 value3A value3B value3C

I found a link to access the value, but please help me in initializing.

Thanks in advance.
