Firebase Development in Exeter
Building on Firebase for Exeter organisations, where the data model follows the screens rather than the entities. Firestore cannot join collections or aggregate cheaply, so information is duplicated into the shape each view needs — and every duplicate is something that has to be kept correct when the original changes.
Why this comes up
The problem
Author names were copied onto every post for display, and renaming an author leaves them stale everywhere.
What you get
What we deliver
- Data modelled around the queries the application actually makes
- Duplication introduced deliberately, with a mechanism for keeping copies current
- Counters and aggregates maintained incrementally rather than computed on read
- Query costs understood, since billing follows documents read rather than time
- Indexes defined for the queries that need them, as composite ones are explicit
- Cloud Functions used for the writes that must not be left to the client

Exeter is the commercial centre for a very large rural catchment, so businesses here routinely serve customers spread across Devon rather than a compact urban area, and travel time is a real cost in every quote.

Firebase Development in Exeter — common questions
- Why is duplication unavoidable?
- Because there are no joins. A screen showing posts with author names either performs a read per author or stores the name alongside the post, and at any scale the second is the only workable option — which makes consistency your responsibility rather than the database's.
- How are duplicates kept correct?
- Usually with a function reacting to the change. When the source record updates, a Cloud Function propagates it to the copies — which needs writing, testing and monitoring, and is the ongoing cost of the model rather than a one-off piece of work.
- How does billing work?
- Largely on documents read, written and deleted. A screen that reads a hundred documents to display ten is charged for a hundred, so the shape of your data has a direct and continuing cost consequence that is easy to overlook in development.
- What about counts and totals?
- They should be maintained rather than calculated. Counting documents to display a total reads every one of them, so keeping a running count updated as records change is both faster and considerably cheaper — and it needs building deliberately.
- Do you work with businesses across Devon?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South West, including Exeter and the surrounding Devon area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Exeter businesses do you usually work with?
- Field service scheduling and routing for businesses covering a wide rural patch, plus professional services systems. Beyond that we work across Higher Education, Professional Services, Healthcare, Retail and Environmental Science.
- Do you cover the areas around Exeter?
- Yes — we work throughout South West, including Plymouth, Truro, Bristol. Exeter is an urban area of roughly 130,000+, and we take on work across the wider Devon region rather than the city boundary alone.
