Sanjay,
	The log is optional, and is provided only for your convenience.
The store is required and there
is the option to use MySQL instead of the native file system.

You can define your own LogFactory and dictate how and what gets logged,
or not use a log at all.  For example,
assume you are creating an acceptor (look in executor.cpp as an
example).

You could either use the provided FIX::ScreenLogFactory(true,true,true),
which would log all in messages, out messages, and events to the stdout.
Or you could disable in and out messages and only log events with the
call
FIX::ScreenLogFactory(false,false,true).  The Acceptor class has a
constructor that allows you to skip logging
all together by not specifying a log factory, for example:

    FIX::SessionSettings settings( file );

    Application application;
    FIX::FileStoreFactory factory( settings );
    FIX::SocketAcceptor acceptor( application, factory, settings);

The log and the store are independent of each other, look at
MySQLStore.cpp/h, FileStore.cpp/h, and
MessageStore.cpp/h to get a starting point for implementing your own
store.

Daniel

Why does QF store messages in a "Log" and a "MessageStore" ? I am trying
to write a class that uses Sybase for storing messages and would like to
understand the rationale behind using log and store rather than a single
store of messages with the necessary funcationality.

Thanks.
