Data modelling - Process
Data modelling
Designing how data should be organised and related so it can be used consistently
What's it for?
Organises information clearly so different people and systems can use it consistently.
For example…
Before a new CRM goes live, the team decides how customers, contacts, and accounts link together.
During data modelling, a team decides whether addresses belong directly to customers or should be separate records that can change over time
Think of it like…
Sketching a filing system before you fill the cabinets, so everything has a sensible home
