Sagot :

Answer:

Data modeling occurs at three levels—physical, logical, and conceptual.

  • A physical model is a schema or framework for how data is physically stored in a database.

  • A conceptual model identifies the high-level, user view of data.

  • A logical data model sits between the physical and conceptual levels and allows for the logical representation of data to be separate from its physical storage.
