Well, I should connect to result.mdb database and performs some 
queries, i.e.
    select * from result order by id
    select * from task where result_id=22
    ...
    select * from parm where task_id=256

then "merge" these records and export into json.

I am a D newbie, and  my plan is:
1. Create a bind to libmdb library (maybe with dstep)
2. Create D code than perform the queries and return record 
(represented in some way, array of struct, tuple...)
4. "Merge" the records
3. Convert these records into json files

Point 3. and 4. are easy, 1. and 2 hard to me ....

Another solution is convert (with mdb-export) mdb into CSV file 
and precess it, but I fear that "query" csv files it is very 
slow...
