Oracle BRM - my understanding

Oracle BRM is more of a tool utilized by a communication industry to
bill their customers based on the usage of the services they offer.3

Unlike oracle application, BRM has separate tool like for each operations (like Customer Centre, Payment Centre).
BRM is a 4 tier architecture and needs more of technical intervention to understand the product.

Originally it was called as Portal, and after Oracle bought it renamed to "Oracle BRM".

Oracle BRM has standard adapter to Seible CRM for Customer centre, and can be integrated to other CRM using AIA.
so most of the BRM users do not use BRM's Customer centre.

My understanding is any customer based organization needs to address their customer complaints (like iSupport module in Oracle) so mostly they always have a very powerfull CRM tool, so having a separate customer centre does not solve their purpose. So most of the customer implements BRM with the integration with their CRM.
