A data model is a (relatively) simple abstraction of a complex real-world data environment. Database designers use data models to communicate with applications programmers and end users. The basic data-modeling components are entities, attributes, relationships, and constraints. Business rules are used to identify and define the basic modeling components within a specific real-world environment.

What does data vault modeling mean?
Data vault modeling is a method used for storing lots of historical data from multiple systems at any one time. It tracks where date has come from and where it is going without making any distinctions between good and better data.
What is statistical modeling?
A statistical modeling system is exactly what it sounds like it would be. This is a model made up from a bunch of data and statistics.
What step in the investigative process would fire modeling using incident data be related to?
Fire modeling using incident data would be related to the analysis step in the investigative process. This involves examining data and evidence to develop insights and conclusions about the fire incident. Fire modeling can help investigators understand factors such as fire behavior, spread, and potential causes.
