Architecture and Implementation
Architecture
Prerequisite for the development of an excellent system is a robust, correctly and well
documented architecture. The architecture's core - the framework - is the result of an intensive
analysis regarding the architecture's quality. Focus lies on non-functional aspects such as
performance, flexibility, security and others. The functionality model of the actual system (described
in use cases) is based on the architecture. This way clear interfaces between the components of the system
and their behaviour are created. The architecture is not only valid for just one product but the whole
familiy of products. Any functional and non-functional change is tested against the architecture:
this ensures the integrity of the architecture ... and prevents code-hacking.
This whole fundamental process work to develop a solid architecture represents a very huge and intellectual
undertaking. It is the reason why only very
few companies are going to invest in truely new rating and billing systems: It is an enormous investment.
The Process ViewThere is a separation of business specific rules and the functional structure of the system. By this we achieve a high level of flexibility for both - implementation of new business-rules as well as changes to the system's structure (eg. new business-event structure, new kinds of business accounts). So the ability to run business processes in parallel is an inherent part of the system structure. And it is clear which system component is responsible for what kind of action. |

The Logical View
Three separate layers with individual responsibilities are one of the most important
elements to easily extend and efficiently maintain the system:
In the business rules layer business scenarios are being described. The type layer encapsulates the structure
of the main components of the system (ie.business partner, event data record etc.).
Finally we have the component layer which builds the skeleton of the system.

Implementation
|
Programming language: 100% pure Java; so it can be run on any system which has a JVM -
a Java Virtual Machine
|
Performance: underlies a permanent verification; although B-oo-levard® is
extremely flexible, it proves excellent processing speed
