Abstract:
"
The existing issue in the telecommunication industry is not having a standard set of APIs to
expose when designing their internal systems which leads to more labour cost and time
consuming when integrating them with existing systems. Telecommunication companies have
already identified the importance of having common API sets in their systems. But they are
having a doubt of implementation whether it could cater existing requirements. It is because
of the complexity of APIs. By this research project the author tried to identify the feasibility
of mapping the data model given by TM Forum Open APIs to a database and implement the
APIs in Customer Management Specification of TM Forum, according to its given features
and performance.
The author has selected Java Spring boot as backend framework and Mongodb as the
database after going through a deep requirement elicitation process to implement the CRUD
of customer as in customer management API specification. An angular UI has provided
incase of demonstrating the work that has been done. By using the aggregation function of
mongodb for projecting only related fields at the time of querying and matching user given
parameters to query even to objects inside objects, the author has developed a common
method to get the TMF approved API query behaviour.
By following the above method the author was able to implement the query function as
approved by TM Forum with filters and fields including other create, update, delete
functions. So that this can be applied when implementing all other TMF Open APIs. As this
research work contains a prototype level system this needs to be developed by adding
advanced business logics according to the requirement of the company, when it comes to
production level implementation"
