The objective of this chapter is to provide guidelines for designing the information view of a software system. It covers the refinement of the persistent object model, the definition of data components based on semantic cohesion, the allocation of these components to appropriate data placeholders within the architecture, the specification of data component interfaces, and the design of object persistence mechanisms. Together, these guidelines enable architects to construct a robust information architecture that ensures data consistency, facilitates modular data management, and supports reliable data storage and retrieval in alignment with system requirements.
