Telecommunications
Set up an operational contract information system. It is mainly used as an order management system—for migrating existing contracts and creating and providing new contract bundles.
Sales agents can use it to order new services, modify existing ones, migrate service types, and provide price information to customers.
This supports especially the marketing of new services and the replacement of old services for existing customers.
Also, the system imports and processes master data (ETL) and provides it via services for further use in the portal front end.

Government
Anonymization of statistical data. A government agency is required to prevent back-calculation of statistical values to original values and thus ensure their anonymization.
For this, mathematical algorithms are applied using noise factors and overlay matrices.
It must be ensured that the final deviations in the results due to the noise factors remain within a defined range.
For the departments and applications, appropriate REST & SOAP web services must be provided that accept the original values (up to 1 million records), process them based on the use case, and return the overlaid values.
In addition, the functional behavior must be tested for correctness and performance, and corresponding module and system tests must be implemented.
