For others, it describes a higher-level concept, which is the definition here. Some people use the term “database model” as a synonym for schema.
You can think of database modeling as a system of architecture and data modeling as a series of flowcharts. Database modeling is a step in database design, whereas data modeling is a process that incorporates analyzing the data and its relations. Thus, database modeling is the process of choosing a structure and creating both a design and schema that will guide how the actual database is built.ĭatabase modeling should not to be confused with data modeling. The model also determines how the data can be interrelated. To start, a database model determines the logical structure of a database and drives the way data will be stored, organized, viewed, represented, and manipulated.
