Data Mapping
The definition of how fields values and structures in one data model correspond to another.
Plain English
A translation plan from one data shape to another.
In context
Data mapping makes transformations explicit so integrations migrations and analytics preserve meaning across systems.
Example
“The mapping converts the source customer_id field to accountId in the target model.”
When you'll hear this
- system integration
- database migration
- ETL design
Common misunderstanding
Matching fields by similar names is not enough when their semantics units or allowed values differ.
