Technology has transformed the way businesses function, and this all boils down to one thing: data. Data has opened the door for businesses to analyse their inner-workings, and make more informed, confident decisions backed up statistics. However, when it comes to the way businesses gather and process their data, there are a variety of revenues for this information and one destination – your company’s systems. So how exactly is this data compiled and broken down? This is where data modelling comes into the equation.
Data models are a necessary part of defining the data a business receives, giving organisations a centre of information to build around. Data models determine how data is represented and used, and it plays an important part in implementing changes to a company’s operations. It is important to trust your data model, and to plan out how you want to gather and store your data.
Different Types of Data Models
There are a number of data model types, each catering to a different business purpose. Each data model has a different processing procedure, which helps businesses comprehend their data and find ways to utilise it.
Star Schema is named after it’s star-shaped diagram, and its purpose is to question huge informational indexes. Star Schema is often used to help business insight, OLAP cubes, analytic applications and impromptu inquires. While it has one of the least complicated architecture, a star schema is one of the more popular data models.
Physical Data Model
A physical data model functions by highlighting the structure of data. This refers to things such as the communication between computer procedures or tables and columns. The formation of the data model changes with the specific needs of the procedures, and works with the information to guarantee successful execution.
Logical Data Model
A logical data model takes the framework of the data components, and then sorts these components into a system, noting the relationship between them. This data model can be the foundation of the physical data model, and also filters the data components which a conceptual data model presents.
Enterprise Data Model
The enterprise data model gives an overview on all data a company may have. This data model gives a broad, yet specific diagram of the organisations data, and helps in creating other database parts such as entity relationship diagrams and XML schemas.
