This thesis provides an overview of different software architectural styles and how they can be used to create a software architecture for a graph-based metadata management for CAE data. Use cases are created to extract software architecture requirements which are the basis for the discussion of the architectural concepts. A concept architecture is presented for each of the software architectural styles. Those are used to discuss the advantages and disadvantages of the architectural styles in the context of the defined software architecture requirements. The REST architectural style and Microservices architectural style both provide the best trade-offs in this context. A final software architecture is introduced that uses both of the architectural styles. This software architecture has been implemented as a prototype which is validated by creating a validation plan for each use case where each step of these plans is mapped to requests of the prototype.
