Legacy System Integration in St Davids
Connecting modern software to the older systems a St Davids organisation still depends on. These systems are usually still running because they work and replacing them is expensive — integration is the pragmatic answer, and it is mostly an exercise in finding a safe way in.
Why this comes up
The problem
A core system from years ago holds data the business needs elsewhere. It has no API, the supplier is unhelpful or gone, and the people who understood it have retired.
What you get
What we deliver
- Access routes assessed — API, database, file exchange, or screen automation as a last resort
- An integration layer in front of it, so nothing downstream is coupled to its quirks
- Read-only access wherever possible, since writing into a legacy system carries real risk
- Data translated at the boundary, including dates and codes that predate current conventions
- Load kept away from production hours, because these systems rarely tolerate concurrency
- Documentation of what was discovered, since the knowledge otherwise leaves again

Thirty minutes, no charge, no sales script. You leave with a written summary of what legacy system integration would actually involve — whether or not you use us.

Legacy System Integration in St Davids — common questions
- What if there is no API?
- There is nearly always another route — a database you can read, a scheduled file export, or a reporting interface. Screen scraping and robotic automation work but are brittle; treat them as a last resort rather than a starting point.
- Is reading the database directly safe?
- Reading usually, with care about load and locking, and ideally against a replica. Writing directly is the dangerous part — legacy applications enforce rules in application code, so writing straight to tables bypasses validation the system assumes has happened.
- Should we integrate or replace?
- Integrate first in most cases. Replacement is expensive and risky, and an integration layer buys time while unlocking the data. It also makes eventual replacement easier, because consumers depend on your interface rather than the old system directly.
- Nobody understands the system any more — is that a blocker?
- It slows discovery rather than preventing it. Data structures can be examined, behaviour can be observed in a test copy, and the resulting documentation is often the most valuable output of the project independent of the integration itself.
- Do you work with businesses across Pembrokeshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including St Davids and the surrounding Pembrokeshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of St Davids businesses do you usually work with?
- Simple booking and payment systems for very small hospitality and tourism operators on the Pembrokeshire coast. Beyond that we work across Tourism & Heritage, Hospitality, Agriculture, Marine and Retail.
- Do you cover the areas around St Davids?
- Yes — we work throughout Wales, including Swansea, Cardiff. St Davids is an urban area of roughly 1,600+, and we take on work across the wider Pembrokeshire region rather than the city boundary alone.
