The EWS Difference

Designed to Perform. Engineered to Last.

Delivered on Time. Every Time.

Data warehouse projects are notorious for overruns - EWSolutions is not. Our proprietary implementation methodology, refined over 28 years and 155+ enterprise programs, eliminates the ambiguity and scope creep that turn warehouse projects into multi-year burdens. We have never delivered a failed program.

Architecture That Scales with Your Business

Short-sighted warehouse design creates technical debt that compounds with every new data source, business unit, and analytics requirement. EWSolutions architects data warehouse environments from an enterprise-scale perspective - so the investment you make today supports the business you will be in five years.

Governance Embedded, Not Added Later

Most data warehouses are built first and governed second - which means retrofitting controls at significant cost. EWSolutions integrates data governance, metadata management, and data quality frameworks into the warehouse architecture from the design phase, preventing the problems that derail warehouse ROI.

BI & Analytics Ready From Launch

A data warehouse that business intelligence tools cannot effectively query is an infrastructure cost, not a business asset. EWSolutions designs data warehouse environments optimized for the analytics and BI workloads your organization depends on - delivering insight velocity from the first production release.

“Mayo Clinic’s Enterprise Data Trust is already realizing palpable success from our cancer center projects, enabling analysis of clinical trial capture and accrual patterns, patient volumes, and clinical trial patient filtering. An infection analytics project standardized data definition and capture of infection-related case data across the enterprise – enabling a single standardized, enterprise-based reporting and analysis environment.”

“David Marco is a real visionary in data management. At the same time, he and the consultants at EWSolutions understand the everyday challenge of managing the enterprise’s data responsibly. Most practitioners can do one but not the other. EWSolutions has the skill and savvy to do both – as well or better than anyone I’ve met. They always worked in the spirit of partnership and were consistently flexible to the changing needs of our project.”

Manager, Consumer/Product Services, Thomson Consumer Electronics

“As Chief Data and Security Officer at UHG’s Ingenix division, I engaged EWSolutions to guide us through a transition of our massive data sets and deploy a Data Governance framework.

What Data Leaders Ask

Data Warehouse FAQs

The questions CDOs and Enterprise Architects ask most when evaluating an enterprise data warehouse consulting partner.

What is enterprise data warehouse consulting?

Enterprise data warehouse consulting covers the strategy, architecture, design, implementation, and optimization of centralized data environments that consolidate data from across the organization into a single, analysis-ready source of truth. EWSolutions delivers the full lifecycle – from requirements and architecture through ETL design, BI layer development, governance integration, and ongoing optimization – so your warehouse delivers measurable business value from the first release.

Why do data warehouse projects fail?

The most common failure modes are scope expansion without governance controls, underestimated data quality challenges, poor metadata management, misaligned business requirements, and architecture decisions that optimize for launch rather than long-term scale. EWSolutions’ methodology addresses all five from the design phase – which is the primary reason our clients complete programs that other firms could not deliver, at 91% lower cost on average.

How long does a data warehouse implementation take?

Timeline depends on the scope of source systems, data volume, and business complexity. EWSolutions typically delivers initial production capability within 90–180 days using an iterative delivery approach that prioritizes the highest-value data and use cases first. Our clients see business value well before the full program is complete – Harvard Pilgrim HealthCare received their first reporting data mart ahead of schedule.

How does data governance fit into a data warehouse program?

Data governance defines the ownership, quality standards, and policy controls that determine whether the data in your warehouse is trusted and used. EWSolutions integrates governance design into the warehouse architecture from day one – establishing data ownership, quality rules, metadata management, and lineage tracking as structural components, not retrofit projects. This is what separates a warehouse that gets used from one that gets abandoned.

Should we modernize our existing warehouse or build new?

This depends on the nature of the constraints in your current environment. EWSolutions delivers a structured assessment that evaluates your existing architecture against your future analytics requirements – identifying whether targeted modernization, phased migration, or a new-build approach offers the best return on investment. We do not default to rebuild when optimization will deliver superior outcomes at a fraction of the cost.

How does a data warehouse support AI and advanced analytics?

AI and machine learning models require clean, consistent, well-governed historical data at scale – exactly what a well-designed data warehouse provides. EWSolutions architects data warehouse environments with AI readiness as a design requirement, ensuring your warehouse supports not just today’s BI workloads but tomorrow’s machine learning and advanced analytics demands. The organizations that invest in warehouse governance today will have the AI-ready data foundations their competitors will spend years trying to build.
