The EWS Difference

Metadata Is the Intelligence Layer of Your Enterprise Data

The Field’s Original Authority

David Marco, PhD authored the definitive books on enterprise metadata management - the texts that established the standards the industry still follows. EWSolutions does not adapt a generic data consulting methodology to metadata; metadata management is our foundational discipline.

Industry-First Big Data Integration

EWSolutions created the industry’s first metadata model integrating Big Data with traditional enterprise metadata needs - a breakthrough that solved the metadata management problem organizations still struggle with today. Our models serve both legacy environments and modern AI-ready architectures.

Lineage That Satisfies Regulators

Regulatory environments demand full data lineage - where data originated, how it was transformed, and who accessed it. EWSolutions builds the metadata infrastructure that makes lineage documentation accurate, current, and audit-ready, eliminating the manual reconstruction that costs organizations weeks before every examination.

The Foundation AI Models Require

AI explainability, model traceability, and responsible AI all depend on knowing exactly what data was used to train and operate each model. EWSolutions builds the metadata management infrastructure that makes AI governance possible - providing the context and lineage that transforms raw data assets into trusted AI inputs.

Leadership

The Pioneer Who Defined the Discipline

“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.”

Stephen C. Grohovsky
Manager, Consumer/Product Services, Thomson Consumer Electronics

“Right from the start David Marco understood the business need and strategic technical challenges of our corporate initiative.

What Data Leaders Ask Us Most

Metadata Management FAQs

The questions CDOs and Enterprise Architects ask most when evaluating an enterprise metadata management consulting partner.

What is enterprise metadata management?

Enterprise metadata management is the discipline of capturing, organizing, governing, and maintaining the contextual information about your organization’s data assets – what data means (business metadata), how it is structured (technical metadata), where it came from and how it moved (operational metadata and lineage), and how it is used (process metadata). Without metadata management, data assets have no reliable context, data lineage cannot be traced, and regulatory compliance cannot be demonstrated. EWSolutions builds the metadata infrastructure that makes data trustworthy and explainable at enterprise scale.

Why does metadata management matter for AI and advanced analytics?

AI explainability, model governance, and regulatory compliance all require knowing exactly what data was used – its origin, its transformations, its quality history, and who had access to it. Without a metadata management infrastructure, organizations cannot answer basic AI governance questions that regulators and boards are increasingly requiring answers to. EWSolutions builds the metadata layer that makes AI governance operational rather than aspirational.

What is data lineage and why does it matter?

Data lineage is the documented history of a data element – where it originated, every transformation it underwent, every system it passed through, and every report or model it ultimately fed. In regulated industries, lineage is a compliance requirement. In AI environments, it is an explainability requirement. In analytics environments, it is a trust requirement. Organizations without lineage documentation spend weeks reconstructing it before every audit – EWSolutions builds systems that maintain it continuously and automatically.

What is a business glossary and do we need one?

A business glossary is the authoritative, governed definition of every critical data term your organization uses – resolving the definitional conflicts between business units that cause executives to receive different answers to the same question from different reports. If your organization experiences “which number is correct?” debates in executive meetings, or if different departments define “customer,” “revenue,” or “active account” differently, you need a business glossary. EWSolutions builds and governs it as a living organizational asset, not a one-time documentation exercise.

How does metadata management relate to data governance?

Metadata management and data governance are inseparable disciplines. Governance defines the rules and ownership – metadata management provides the context and lineage that makes governance enforceable and auditable. A governance program without metadata management cannot demonstrate compliance. A metadata management program without governance has no accountability structure to maintain it. EWSolutions designs both as a unified program, which is a key reason our clients achieve the cost reductions and audit outcomes that generic consulting cannot replicate.

What does EWSolutions’ industry-first metadata model deliver?

EWSolutions created the industry’s first metadata model that integrates Big Data environments with traditional enterprise metadata needs – solving the fragmentation problem that emerged when organizations began operating data lakes, streaming platforms, and cloud environments alongside legacy data warehouses. Our model provides a unified metadata architecture across all data environments, eliminating the metadata silos that make lineage tracing, impact analysis, and AI governance impossible at enterprise scale.
