I'm still trying to understand the internal elements of core banking
and their interactions; only to a practical level.
in the end, will all ISO traffic ends up in the database? if so can I
just interact with the DB? what will I need? SQL-to-ISO decoder? i think
NOW i'm more comfortable working with SQL than XMPP.
