Data warehouse consulting
Consulting settles the questions that decide the project before budget is committed: what the warehouse must answer, which sources feed it, and what “done” means for your business. When the contested priorities span the whole data estate rather than one warehouse, data strategy consulting resolves them first.
An assessment of your sources, reporting needs, and data maturity, written down
A recommendation you can challenge, with the reasoning behind it written out
A scope your finance team can put a number against
Data warehouse platform selection
Platform selection scores Snowflake, BigQuery, Amazon Redshift, Databricks, and Microsoft Fabric against your workloads, team skills, and budget — a decision made on the merits, documented so it survives staff turnover.
A scored comparison against your query patterns, volumes, and compliance constraints
A total-cost projection for the first year of running each shortlisted platform
The trade-offs in writing, so the decision has an owner and a rationale
Implementation planning and roadmap
Planning turns the chosen platform and scope into a phased roadmap: stages, dependencies, and a priced first release.
Phases with dates and sign-off points, so progress is checkable from the outside
A first release scoped around the reports your business asks for most
Risks named upfront, each with a mitigation and an owner
Data warehouse deployment and configuration
Deployment stands the warehouse up in your environment: accounts, security, environments, and cloud data warehouse configuration tuned to your actual workloads. Changes ship through blue/green deploys, so every release has a tested way back.
Role-based access, encryption with customer-managed keys, and data residency in the EU or UK where your regulator requires it
Separate development, staging, and production environments, provisioned as code and staged from zero-copy clones
Compute and storage configured for your query patterns, with cost guardrails on
Source onboarding and rollout
Rollout brings your systems into production one source at a time, so working reports arrive early instead of all at once at the end. Each source loads its history as a backfill, then runs in parallel with your existing reporting until the numbers match. High-volume feeds, events, IoT, and raw logs, land through big data services, so the rollout pace never hangs on your heaviest source.
Sources prioritized by the business value each one unlocks
Each source validated against the system it came from before reports depend on it
A cutover plan per source: a freeze window, dual-write or CDC sync, and a rollback path sized to your RPO and RTO
BI and reporting integration
Integration connects the warehouse to Power BI, Tableau, or Looker, so answers appear where your teams already work — with dashboards and reporting built through AI-powered data analytics services.
Semantic layer and metric definitions shared across every BI tool you run
Existing dashboards repointed to the warehouse without breaking their numbers
Report performance tested at your real concurrency and data volumes
Implementation rescue and takeover
A stalled or failing implementation rarely needs a restart — it needs an audit and a completion plan.
An audit of what exists: platform, pipelines, model, and what’s salvageable
A completion plan with the remaining work priced and dated
The handover discipline the first attempt was missing: documentation, tests, sign-offs
Team training and adoption
Adoption decides whether the warehouse gets used or quietly bypassed. Training runs inside the implementation, priced in the phase plan.
Working sessions with the analysts and report owners who inherit the platform
Runbooks and a self-service starter kit for the questions teams ask most
An adoption check after launch: who’s using it, who isn’t, and why
How a data warehouse implementation engagement works
An assessment you could take to another vendor
Your sources, reporting needs, and constraints go into a written assessment with a recommendation and its reasoning. Useful even if the build never happens here.
A platform decision with the trade-offs on paper
The shortlisted platforms get scored against your workloads, skills, and budget. You make the call; the scoring survives as documentation.
A phased roadmap your finance team can read
Scope becomes phases — each priced, dated, and ending in a sign-off you control. The first release is scoped around the reports your business actually waits for.
A warehouse built and wired to your sources
The build phase runs through our data engineering services: architecture, data model, and pipelines, with every merge passing senior review. Sources go live one at a time, validated against the systems they came from.
A launch signed off against the numbers
Reports are reconciled to source systems and performance is tested at your projected load before anyone depends on the warehouse. The sign-off is yours, with the evidence attached.
A team that can run it without us
Training, runbooks, and an adoption check after launch. Support continues at the level you choose — from advisory to full operation.

What clients are saying about Relevant
4.9 is our Clutch average
The platform is standard. Your sources aren’t. Implementation is where they meet.
A phased rollout brings them together one validated source at a time — what happens, when, and what it costs, in the open.

What drives the cost and timeline of a data warehouse implementation
The number of source systems
Every source adds a connector, a validation pass, and a cutover plan. Source count is the single biggest driver of both budget and duration.
Data volume and history
Volume and history depth set the initial load and the storage bill. On modern cloud platforms, storage is the cheapest part of the project — the budget follows engineering effort.
The complexity of your business logic
A metric with one agreed definition is a line of code. A metric that finance and sales compute differently is a workshop first, then a line of code. The more definitions your teams dispute, the larger the share of budget that goes to alignment before engineering.
Compliance requirements
GDPR, HIPAA, SOC 2 Type II, PCI DSS, or EU and UK data residency each add access control, lineage, and audit work. Planned from the start, it adds a few percent; retrofitted after launch, it adds rework.
How much your team takes on
A full pod runs a data architect, data engineer, analytics engineer, BI developer, and DevOps engineer. The more of those seats your own team fills, the lower the external cost and the longer the timeline. The phased plan states the split per phase and prices both options.
Frequently asked questions
We've decided on a warehouse. What actually happens in the first month?
The first month is assessment and decisions. Your sources, reporting needs, and constraints go into a written assessment; platforms get scored against your workloads; and the scope becomes a phased roadmap with a price and a date per phase. Nothing irreversible happens in that window — which is the point: the expensive commitments come after you’ve seen the plan. A useful preparation you can do today: list your source systems and the ten reports leadership actually waits for. Those two lists are most of what the assessment needs.
How is the cost of a data warehouse implementation structured?
Expect the budget to follow the phases: assessment and platform decision first, then a priced first release, then increments per source and per reporting domain. Five variables set the totals — the number of sources, data volume, the complexity of your business logic, compliance requirements, and how much your own team takes on. All five are computable before anyone sends you a quote. Bring them to a scoping call and the conversation starts from your numbers — contact us and the first thing you’ll get back is a phased read.
Snowflake, BigQuery, Redshift, Databricks — how should we choose?
The honest method is scoring: your query patterns, data volumes, team skills, existing cloud estate, and compliance constraints, weighed against each platform’s economics. A quick self-check that predicts most outcomes: name your primary cloud, your BI tool, and whether ML workloads are on the roadmap. Google-centric with event analytics points one way, a Microsoft estate with Power BI another, ML alongside BI a third. Be wary of any recommendation that arrives before those questions are asked — platform advice shaped by a reseller partnership tends to skip them.
Our implementation stalled halfway with another vendor. Is a restart inevitable?
Rarely. Most stalled implementations keep their platform and much of their pipeline work; what failed is usually scoping, sequencing, or sign-off discipline. What happens first is an audit — what exists, what’s salvageable, what the gap to production really is — and the audit result is a completion plan with the remaining work priced and dated.
Run your own check before any call: ask the current team for the phase plan and the last sign-off document. If neither exists, the gap is scoping discipline, and that’s fixable with the code you already have.
Does implementation include building the warehouse itself, or is that a separate project?
Implementation covers the decisions and the delivery frame: assessment, platform, roadmap, rollout, launch, adoption. The engineering inside it — architecture, data modeling, pipelines — runs through data warehouse development services, as a phase of the same roadmap rather than a separate contract. The distinction matters when comparing vendors: an “implementation” quote that doesn’t name who does the engineering, in what phase, and under whose review, is a quote with the expensive part missing.
How do we know the implementation succeeded?
Define success before the build, then measure against it: reports reconciled to source systems line by line, performance tested at your projected load, and the criterion that decides whether the rest mattered, adoption, meaning the teams that asked for the warehouse actually run their reporting on it.
Each phase closes with a sign-off you control, so “done” stays your call. A drill worth running at any vendor’s final demo: pick one number on one dashboard and ask them to trace it back to the source system while you watch. That trace either exists or it doesn’t.
Who works on the implementation, and what roles do we need on our side?
A full implementation pod runs five roles: a data architect who owns the model and platform decisions, a data engineer building pipelines, an analytics engineer turning raw tables into the metrics your reports use, a BI developer on the dashboard layer, and a DevOps or platform engineer for environments and provisioning. You staff any of those seats yourself where you already have the skill, and the phased plan prices both splits. From your side the fixed asks are smaller: a source-system owner for access and edge cases, and report owners for sign-off at each phase.
Will our team be able to run the warehouse after launch, or are we dependent on you?
Independence is a deliverable: training sessions with your analysts and report owners, runbooks for the routine work, and an adoption check after launch that names who’s using the platform and who’s still exporting CSVs. Day-to-day operation is realistic for one technically-minded owner; what needs engineering time is change — new sources, new metrics, growing volumes — and that you can staff in-house, keep with a dedicated teamon our side, or split between the two. Nothing in the delivery locks you in: the accounts, code, and documentation are yours from the first phase.
