This document provides an overview of message-oriented middleware and how OpenMAMA can simplify infrastructure. It discusses that MOM provides applications a way to communicate without direct connections. OpenMAMA is an open source, middleware-agnostic messaging API that supports various messaging platforms through a consistent abstraction layer. It allows applications to be coded once and easily upgraded regardless of the underlying middleware.

3. What is Message Oriented Middleware?
• MOM provides a means for applications to send
information to each other, without establishing explicit
connections, and with little-to-no knowledge of each other
• Two common paradigms: publish/subscribe and queuing
• Topic based naming for routing of messages
• A messaging API is typically proprietary to its own
messaging service

8. Origins of MAMA to OpenMAMA
The MAMA API was originally conceived in 2002 with the goal of enabling
banks and hedge funds to distribute Market Data throughout their ticker plants
regardless of the underlying middleware. This solution was expanded and
refined and in 2003 when the MAMDA API was introduced providing a market
data specific API, abstracting quotes, trades, order books, option chains and
other market data constructs on top of MAMA.
MAMA & MAMDA gave the financial services industry a new level of flexibility
by providing a solution which allowed organizations to standardize distribution
over multiple middlewares. This resulted in reduced development times,
leading to lower costs, reduce complexity and broader support for a range of
interconnected systems and applications.
With almost 10 years of production mileage under its belt and over150 clients
MAMA & MAMDA evolved into the de facto standard for messaging within the
financial services industry. Building on that history OpenMAMA is expected to
lead innovation in the industry as the open standard for messaging in
financial services driven by customers, vendors and industry thought leaders.
