Cas client International Airport: local data center architecture and implementation

International Airport: local data center architecture and implementation
Context
Working at an international airport, our challenge was to help our client define and implement a data architecture to interconnect HR process tools. The objective was to facilitate the migration to a new HR ERP developed by SAP. The client's IT environment included several applications, software packages and specific developments that supported a complex HR process. These data exchanges were currently managed using a static data exchange architecture (encrypted DataFlows). As the IT environment evolved, it became imperative to improve data exchanges to facilitate change, integrate new software packages and optimize the integration of digital tools. Our intervention included a needs assessment, the design of the target data architecture from a functional and technical point of view, as well as on-site implementation support.
Challenges
The main challenges of this initiative were to enable more flexible data exchanges to adapt to changes and to integrate several important functions, such as quality management, lineage and the audit trail of exchanges. The complexity of the HR process required the evolution of the static architecture to a more dynamic solution, capable of responding to the customer's evolving needs.
Solution and method
To meet these challenges, we proposed the implementation of a DataHub On Premise, following the key steps:
Determination of the scope of requirements to inventory and model in detail all functions linked to the affected business process.
Development of a target data model, which will form the core of the DataHub.
Detailed description of the algorithms to guide the development of the tasks.
Support to developers during the implementation of complex algorithms.
Benefits
The results achieved have led to a significant improvement in data exchanges, enabling more flexible change management, a smoother transition to new software packages and better integration of digital tools. The implementation of the DataHub On Premise has increased the flexibility and robustness of the IT landscape, bringing significant benefits in terms of efficiency and performance.
