FAQs

What is a data mesh?

+

A data mesh is an operating model where domain teams own their data as a product, with shared platform tooling and federated governance, rather than one central team owning everything. It’s an organizational design more than a technology. It works when domains have the skills and the mandate to own their data.

What is an analytics engineer?

+

An analytics engineer builds the modeled, tested datasets that analysts and dashboards use, applying software engineering practice to transformation work. They sit between the data engineer, who moves and stores data, and the analyst, who answers questions with it. dbt is the tool most associated with the role.

What is data lineage?

+

Data lineage is the record of where a piece of data came from and what happened to it along the way, from source through each transformation to the dashboard. It answers which report breaks if a source column changes. dbt derives it automatically from ref() and source().

What is data orchestration?

+

Data orchestration is coordinating the tasks in a pipeline: deciding what runs, in what order, what it depends on, and what happens on failure. Airflow is the common choice. It’s distinct from transformation, which is what the individual tasks do.

What is the difference between a data engineer and an analytics engineer?

+

A data engineer builds and runs the infrastructure that moves and stores data: ingestion, pipelines, orchestration and the platform underneath. An analytics engineer works on the data once it has landed, modeling it into tables the business can use. One owns delivery, the other owns meaning.
