dbt Implementation in Cardiff

Implementing dbt for Cardiff organisations, where teams routinely adopt it for the transformations and skip the part that matters most. Tests run with every build and catch a broken assumption before it reaches a report — and a project with hundreds of models and no assertions has organised its SQL without improving whether anyone can trust the output.

Why this comes up

The problem

The project has two hundred models, no tests, and a source system change silently corrupted a metric for three weeks.

What you get

What we deliver

  • Tests written alongside models rather than deferred to a later phase
  • Source freshness checked, so stale upstream data is caught before it propagates
  • Model layers established — staging, intermediate and marts — with a naming convention
  • Documentation generated from the project rather than maintained separately
  • Incremental models used where full rebuilds have become expensive
  • Continuous integration running tests on every change before it is merged

Working in Cardiff

Wales

Cardiff has a significant broadcast and media sector alongside a large public-sector presence, and Welsh-language provision is a genuine requirement on public-facing work here rather than a nice-to-have.

Public sector and broadcast work is common, and bilingual provision is usually a requirement rather than an option.

dbt Implementation in Cardiff — common questions

Why are tests the important part?
Because they are what makes the pipeline trustworthy. Organising SQL into models improves maintainability; asserting that a key is unique, a value is never null and a relationship holds is what stops a broken assumption reaching a dashboard nobody questions.
What should we test first?
Primary keys, nullability on fields the business depends on, and referential integrity between models. Those catch the majority of real breakages and take very little time to declare, which makes them the obvious starting point rather than an exhaustive suite.
Why layer the models?
So changes have a predictable blast radius. A flat project where anything can reference anything produces a dependency graph nobody can reason about, and layering with a convention means a developer knows what they may safely alter without tracing every downstream model.
When are incremental models worth it?
Once full rebuilds become slow or expensive enough to notice. They add complexity — late-arriving data and backfills both need handling — so building everything incrementally from the start is premature, while leaving a large table rebuilding nightly eventually is not.
Do you work with businesses across Cardiff?
Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Cardiff and the surrounding Cardiff area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of Cardiff businesses do you usually work with?
