Tableau Implementation in Derry
Implementing Tableau for Derry organisations, where the choice between extracts and live connections governs both speed and freshness. An extract is fast and as current as its last refresh; a live connection is always current and passes every interaction through to the source — and the right answer differs per workbook rather than being a platform-wide policy.
Why this comes up
The problem
Everything uses live connections, the warehouse is under constant load, and dashboards respond slowly for everybody.
What you get
What we deliver
- Extract or live decided per data source against freshness and performance needs
- Extract refresh scheduled around when the underlying data actually changes
- Published data sources established so workbooks share rather than duplicate
- Row-level security applied at the data source where users must see different data
- Workbook performance examined, since the design affects the queries generated
- Publishing conventions agreed before the server accumulates duplicates

Tableau Implementation in Derry — common questions
- Extracts or live connections?
- Extracts for most reporting, live where the data must be current to the minute. Extracts are considerably faster to interact with and reduce load on the source, and the freshness they lose is irrelevant for the many dashboards reviewed daily or weekly.
- What is a published data source for?
- Sharing a prepared, secured connection across workbooks. Without them each workbook carries its own connection and its own calculations, so the same metric gets defined repeatedly and the definitions drift apart over time.
- How much does workbook design affect performance?
- Substantially. Filters, calculations and the number of marks all influence what is executed, and a dashboard that appears simple can generate expensive queries — examining the performance recording is usually more informative than guessing at causes.
- Why agree conventions before publishing?
- Because a server without them fills with near-duplicate workbooks very quickly. Deciding where things are published, how they are named and who owns them costs an hour at the start and saves a substantial clean-up exercise later.
- Do you work with businesses across County Londonderry?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Derry and the surrounding County Londonderry area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Derry businesses do you usually work with?
- Cross-border trading systems for businesses working into Donegal, and manufacturing tooling for the north west. Beyond that we work across Manufacturing, Healthcare, Higher Education, Digital and Tourism.
- Do you cover the areas around Derry?
- Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Derry is an urban area of roughly 85,000+, and we take on work across the wider County Londonderry region rather than the city boundary alone.
