Most of the offered services were documented in Amdocs Cramer OSS manually using the Wizards or pieces of documentation were shared between the systems. In other words, there was no unified data storage. Having studied all the weak and strong points of the old API, it was decided to design and implement a brand new application programming interface new API that exposes high-level operations and conforms to modern enterprise standards and trends.
The business processes had to be investigated carefully, classified and then reflected to API operations, domain model and states of its objects. The new API has to cover the following key features Allow management reserve, release and change physical ports, nodes, etc.
Provide by request 3rd party systems details about documented services, as well as physical and logical network inventory associated to them. Client-server exchanging based on the SOAP protocol. Expose utility public operations which allow to retrieve object instances from the Cramer OSS object model. The new API and back-end solution has to meet high performance requirements. The project was coupled to the beginning of transition to new API on all dependent 3rd party systems. Which led to more activities for project timeline and phase planning activities.
The Solution During the analysis phase of the project, we designed entities representing the domain model affected by the project scope , and it was decided to represent the business process for documenting services as set of atomic operations subprocesses.
Each operation is responsible for a small part of business process flow. Once the operation is completed, it moves all associated objects to certain state, while the next subprocess uses them as input objects. Thus, sequential and sometime parallel execution of the subprocesses leads the planned result. For each atomic operation we estimated the amount of activities to fulfill the subprocess.
Changes made by subprocesses can be adjusted or rolled back via "release" and "change" operations provided by the new API. For instance, when service is no longer required for a customer, it can be deleted from Cramer OSS as well as all associated objects. This technology was chosen because it is a de facto standard for enterprise application and wide range of systems support it out of the box.
Essentially, the web service acts as a buffer proxy tier. Once this phase is complete, all concerned 3rd party systems are going to be switched to the new implementation, access to the old API will be smoothly switched off.
The new API has to reach the following key points Significant increase in the amount and speed of processed data, thanks to wide range of automatic operations and high performance. Provide flexible solution for the cases of launching a brand new product: set of operations provided by the new API can be extended, and business-logic changed without significant efforts.
Sub-Projects On-site Analysis — the initial phase of the project involved a face-to-face meeting with the client and its project team to discuss the challenges, gather requirements, design the solution, and finally develop the high-level solution HLS document. Cramer Customization — since the project touches business process, Amdocs Cramer OSS also had to be customized so as to meet new requirements. The documentation for the services is shared between several enterprise applications, and had to be extracted before the load.
