Final answer:
In logical database modeling and design, combining data from all user interfaces into a unified model is called view integration, which is critical for maintaining data integrity and reducing redundancy.
Step-by-step explanation:
In logical database modeling and design, the process of combining normalized data requirements from all user interfaces into one consolidated logical database model is called view integration. The aim of this process is to ensure that a cohesive and unified database structure is in place to support the data needs of different areas of an organization while maintaining data integrity and reducing redundancy. View integration is a critical step in creating an efficient and effective database system. It enables different users and applications to have their data requirements met without the need for multiple versions of similar data, helping to keep the database streamlined and robust. The correct answer to the question is B) Integration.
