i want something like the DB connection naming service by oracle in
Java! https://docs.oracle.com/cd/B28359_01/java.111/b31224/urls.htm#BEIDHCBA

Of course less complicated! using statics names and developer just
need to modify parameters, no code modifications need!

but i like your idea, i can set a "Conex" property that choose a db
name from the AllDbs pool, and have a factory that loop over the
configuration file

i'll try to do something with your class and report feedback later
