The
analysis of data objects and their relationships to other data objects. Data
modeling is often the first step in database design and object-oriented
programming as the designers first create a conceptual model of how data items
relate to each other. Data modeling involves a progression from conceptual model
to logical model to physical schema. Data modeling is the process of
documenting a complex software system design as an easily understood diagram,
using text and symbols to represent the way data needs to flow.

Traditionally,
data models have been built during the analysis and design phases of a project
to ensure that the requirements for a new application are fully
understood. A data model can be thought of as a flowchart that
illustrates the relationships between data.
