Data modeling is the study of data objects and their relationships with other data objects. It is the first step in designing and developing a database, as data modeling enables designers to create a conceptual data model of how each data item is related to the other. Data modeling also provides visual representation of data and its organization, for example the entity relationship diagram (erd). It also forms an importance part of all database solutions.
DATA MODELS HAVE MULTIPLE LEVELS INCLUDING
Conceptual data model:
This defines the problem that needs to be addressed in your business. Conceptual data model is developed first and it includes entity relationships.
Logical data model:
This provides a logical solution to a data base project. Logical data model provides solutions on various problems identified in the conceptual data model and presents a platform for the creation of database.
Physical data model:
This describes the implementation of the modeling or logical data model in a physical database. Physical data model is developed after logical data model is designed.
