Logical data models can be used to model relationships between different pieces of information. Physical data models are based on the physical world. They useimensional representations of information and can generate results that reflect the reality of the world. Physical data models can be used to model relationships between different pieces of information.

This model is used to predict or understand how the data will look when it is used. It can also be used to identify patterns in the data. A hierarchical data model is a model in which the relationships between different elements are represented as levels of hierarchy. This model can be used to group related information together or to separate different types of information. A relational data model is a model in which the relationships between different objects are expressed as relations between them. This type ofmodel can be used to store information in aorganized way so that it can be accessed easily by computers.

Ordinal data is just the order of things, so you might have a list of numbers like "5" but also "1, 2, 3, 4" or "8". Discrete data is just a number and doesn't have a specific meaning. Continuous data is like when you hear someone say "I'm going to run outside for a minute" and then they leave the room. You know they're going to come back later because you hear them talking about running outside again later on.
