CDE Systems was set up in 1999 to design, build and look after database applications for businesses and public bodies. More than 25 years on, it’s still what we do./azure-cloud/
Most of our work now is on systems that already exist. That includes ones somebody else built, that the business depends on every day, and that nobody else wants to touch.
You’ll deal with the people who do the work. The system, the data and the documentation stay yours, and the source code of anything we build is held in escrow, so the business never depends on us still being here.

Who we work with
Public, private and voluntary sector organisations, some of them for over twenty years.
Central government. Department for Work and Pensions · Department for Education · Department for Business and Trade
Public sector and education. National Health Service · Sheffield City Council · Sheffield Hallam University · Northumbria University
Business. Scania Trucks UK · Yorkshire Building Society · DDB London · Aire Valley Catering · Dearson Winyard International · Delta Resins · Lilleker Engineering · · Portobello-RMF Engineering · Resolve IT Solutions · T&C Training Services · Trakker Products
Large organisations and small ones. Quite a few started with one problem and stayed.

Systems that already exist
Most software companies want to build something new. We spend most of our time on the systems businesses already run on.
That means Microsoft Access databases, SQL Server applications and bespoke business software. It also means reporting systems, older applications, and setups that mix desktop, web and cloud.
People usually call us when one of those needs specialist attention. It may have broken, or no one understands it any more. It may not do what the business now needs, or the person who looked after it may have gone.
Starting from the business, not the database
Technology problems are rarely only technical. Behind every database is a process, and behind every report is a decision someone has to make. Behind every application is a team relying on it to get through the day.
So we start by understanding how the system supports the organisation, as well as how it’s built. That’s what makes the advice useful and affordable, and not just technically correct.
How we work with a business
Most of our client relationships start with a problem. It might be a system down, data to recover, an urgent change, or a developer who has disappeared.
They tend to become something longer. Once we know a business, support gets quicker, development costs less, and planning ahead gets easier. Knowing the history of a system, the people using it and where the organisation is heading beats starting from scratch every time. Clients mention continuity more than anything else, and the business is built around it.
