Moving down the line of SOA patterns that are used in core technology frameworks, we finally come to Business Activity Monitoring; this term was proposed by Gartner during the earlier years of SOA development. Actually, this term has no relation to any recognized SOA pattern (with the exception of UI Mediator, but very remotely), but every Oracle-technology-related book (related or not related to SOA) has a chapter dedicated to BAM.

You can find them a lot in chapter 19 of the book by Lucas Jellema, which has already been recommended. It's quite typical that you will find guidance on BAM somewhere around the final chapters of this book. Quite interestingly, it contradicts the common corporate purchase practice; usually, BAM is purchased first and implemented in the end.

Why is that? It's quite obvious; top managers love the dashboards full of colorful 3D pie charts, but development teams have to go a very long way before something really useful becomes available...
