Associative arrays will be included in the next version of Ada, as part
of the standard container library:

ada.containers.hashed_maps
ada.containers.indefinite_hashed_maps

There will also be an ordered version (which does the same thing as the
hashed version, but with a different time complexity; it's also a bit
simpler to instantiate):

ada.containers.ordered_maps
ada.containers.indefinite_ordered_maps

There are also hashed and ordered sets (for use when you don't need a
separate key and element).

You can get a reference implementation in the ai302 subdirectory at the
charles.tigris.org website.

Look for the files named a-c*.ad[sb] .
