What is the process of determining users' information needs and identifying relationships among data called?

The process of determining users' information needs and identifying relationships among data is aptly defined as data modeling. Data modeling involves the creation of visual representations that outline how data is structured, organized, and related within a system. This practice is essential for understanding user requirements because it helps in forming a clear framework of data elements, their attributes, and the associations between different datasets.

Data modeling serves as a blueprint for designing databases and ensuring that all necessary information can be efficiently retrieved and utilized. It provides insight into how various pieces of data interact, ensuring that the structures built meet the specific needs of users and stakeholders. Essentially, this foundational work is critical for developing effective data management systems and improving decision-making processes within organizations.

In contrast, data mapping focuses on the transformation of data from one format to another, decision support refers to the use of data to aid in making business or clinical decisions, and interoperability describes how different systems can work together and share information but does not directly address the identification of user needs or relationships among data.
