data-mapping

Vocabulary Word

Definition

Data-mapping is the process of associating different types of data with each other. It's like creating a blueprint that lets a computer system connect, for example, a product id with its price, inventory levels, and color options.

Examples in Different Contexts

For ETL (Extract, Transform, Load) processes, 'data mapping' involves defining how data from the source system is transformed and loaded into the target system. An ETL developer might explain, 'Through data mapping, we specify the transformation rules that convert source data into a format suitable for analysis in our data warehouse.'

Practice Scenarios

Tech

Scenario:

I'm seeing a lot of duplicate data on our system. We need to find a way to consolidate these data points for streamlined analysis.

Response:

Agreed, we need to create a data-mapping schema to consolidate the duplicate data from our system.

Academics

Scenario:

Our survey result analysis is missing some links between participants' demographics and their responses.

Response:

Perhaps we should refine our data-mapping to effectively connect participants' demographics to their survey responses.
