The Meaning of Data Modeling
In the field of software engineering, data modeling plays a pivotal role in shaping the foundation of data-driven systems. It involves the careful creation of data models by employing formal data model descriptions through a range of data modeling techniques.
At its core, data modeling serves as a method to define and scrutinize the data requirements essential for supporting an organization’s business processes. These data requirements are documented in the form of a conceptual data model, complete with associated data definitions. The transformation of this conceptual model into an actionable blueprint is what we refer to as a logical data model.
