Data modeling is the technique that visually represents the concepts (entities), their attributes, and the relationships within a solution or business domain. It organizes requirements by structuring how data is stored, processed, and connected, ensuring clarity and alignment with business needs.
The BABOK Guide (Chapter 10: Techniques - Data Modeling) highlights data modeling as a method to define and analyze data requirements, providing a clear framework for understanding the business domain.
Examples include entity-relationship diagrams (ERDs) or class diagrams, which explicitly show concepts and their interconnections.
BABOK Section 10.8: Data Modelling, data modeling is a technique used to represent the concepts and their relationships within a particular solution or business domain. Data modeling visually illustrates how data elements relate to each other, providing a clear understanding of the structure and organization of data relevant to the business or solution. This technique is essential for defining and organizing requirements as it ensures that all data needs and relationships are accurately represented and aligned with the business objectives.
