Abstract:
We report on experience that we made in the Trading room
InteGRation Architecture project (TIGRA) at a large German
bank. TIGRA developed a distributed system architecture
for integrating different financial front-office trading applications
with middle- and back-office applications. We generalize
the experience by proposing an architectural style that
can be re-used for similar enterprise application integration
tasks. The TIGRA style is based on a judicious combination
of object-oriented middleware and markup languages.
In this combination an object request broker implements reliable
trade data transport. Markup languages, particularly
the eXtensible Markup Language (XML), are used to address
semantic data integration problems. We show that the
strengths of middleware and markup languages are complementary
and discuss the synergies yielded by deploying middleware and markup
in the TIGRA style.
