Data Documentation Services
Keep data knowledge out of people’s heads.
Every data team has hidden knowledge.
- Which dashboard is still used.
- Which table is reliable.
Which metric has edge cases. - Which SQL logic nobody should touch.
- Which field looks simple but means something very specific.
We help document the datasets, dashboards, metrics, and transformations your team depends on, so people can find answers without asking the same questions again and again.

Keep data knowledge out of people’s heads.
Every data team has hidden knowledge.
- Which dashboard is still used.
- Which table is reliable.
Which metric has edge cases. - Which SQL logic nobody should touch.
- Which field looks simple but means something very specific.
We help document the datasets, dashboards, metrics, and transformations your team depends on, so people can find answers without asking the same questions again and again.
When data knowledge is scattered, teams slow down
As companies grow, data knowledge spreads everywhere.
- Some of it lives in dashboards.
- Some of it lives in SQL.
- Some of it lives in Slack.
- Some of it lives in old tickets.
Most of it lives in people’s heads.
That works until the data team grows, people leave, dashboards multiply, and business users start asking the same questions every week.
Good data documentation makes data easier to find, understand, trust, and maintain.
It helps analysts move faster.
- It helps business users use data with more confidence.
- It helps business users use data with more confidence.
- It helps new team members onboard without needing weeks of explanation.
What we help you document
We focus on the data assets that matter most to reporting, analytics, operations, leadership decisions, and future AI use cases.
Datasets
We document key datasets, tables, models, and views.
This includes what each dataset is used for, where it comes from, how often it updates, who owns it, and which reports depend on it.
Dashboards and reports
We create an inventory of dashboards and reports.
We document who uses them, what decisions they support, which metrics they include, and whether they are still trusted.
Transformations
We document the logic behind important transformations.
This includes joins, filters, calculations, exclusions, business rules, and dependencies.
Ownership
We make it clear who owns each dataset, dashboard, metric, or business definition.
Ownership is what keeps documentation alive after the first version is written.
Fields and columns
We explain important fields in plain language.
Not every column needs a paragraph. But critical fields need clear definitions, accepted values, edge cases, and usage notes.
Metrics
We document metric definitions, formulas, filters, source tables, owners, and business interpretation.
This connects directly with your metrics dictionary and KPI framework.
Business terms
We create glossary entries for important business concepts.
This helps data teams and business teams use the same language.
What you get
At the end of the project, your team gets a practical data knowledge base.
Not a huge document nobody reads.
Not a static spreadsheet that goes out of date in two months.
A usable structure your team can maintain.

How we work
Find the critical data assets
We do not start by documenting everything.
We identify the dashboards, datasets, metrics, and reports that are most used, most trusted, most risky, or most misunderstood.
Review existing knowledge
We review your dashboards, warehouse models, BI tools, dbt models, notebooks, spreadsheets, tickets, docs, and existing definitions.
The goal is to collect what already exists before creating anything new.
Speak with the people who know the data
Some of the most important knowledge is not written down.
We work with analysts, data engineers, business owners, and regular users to understand how the data is actually used.
Create clear documentation
We turn scattered knowledge into clear documentation.
The language is practical. The structure is easy to scan. The level of detail fits the asset.
Connect documentation to daily work
Documentation should live where people look for answers.
That may be in a data catalog, BI tool, dbt docs, Confluence, Notion, SharePoint, GitHub, or another internal knowledge base.
Set ownership and review rules
We define who keeps each area up to date and how changes should be reviewed.
Documentation only works when maintenance is part of the process.
Common problems we fix
“Only one analyst understands this table”
We document the dataset, logic, usage, and known risks so knowledge is not locked inside one person’s head.
“Nobody knows which dashboards are still valid”
We review dashboards, map owners, identify duplicates, and flag outdated or risky reports.
“The same field means different things in different places”
We define important fields and explain where they should and should not be used.
“New analysts take too long to onboard”
We create documentation that helps new team members understand the data landscape faster.
“Business users keep asking the same questions”
We document definitions, dashboard purpose, metric logic, and usage notes so answers are easier to find.
“We want a data catalog, but we are not ready”
We prepare the documentation, glossary, ownership, and metadata structure needed for a useful catalog.
Best fit
This service is a good fit if:
- your data team answers the same questions every week;
- key data knowledge lives in people’s heads;
- dashboards and datasets are not clearly owned;
- new analysts take too long to understand the data;
- business users do not know which report to trust;
- you are preparing for a data catalog;
- you are building self-service BI;
- you need better documentation for analytics, reporting, or AI;
- your team is too busy to document properly.
Not a fit if
This may not be the right first step if your data assets are still changing every week and the core reporting layer is not stable.
In that case, it may be better to start with a data warehouse cleanup, BI audit, or metrics system project before documenting everything.
Documentation works best when there is something stable enough to document.
Why Data Never Lies?
We document what people actually use
We do not document every table just because it exists.
We focus on the datasets, dashboards, metrics, and logic that affect reporting, decisions, operations, and trust.
We write for humans, not just data teams
Technical accuracy matters. But documentation also needs to be readable.
We make definitions clear enough for business users and detailed enough for analysts.
We connect documentation with ownership
Documentation without ownership goes stale.
We help define who owns each asset and how updates should happen.
We prepare your data for catalog, quality, and governance work
Good documentation becomes the base for data catalogs, data quality rules, metric governance, and self-service analytics.
What we usually document first
The best starting point is usually not “all data”.
It is the data that creates the most business value or the most confusion.
Common starting points include:
executive dashboards
revenue reporting
sales pipeline reporting
finance metrics
customer reporting
marketing attribution
product analytics
operations reporting
data warehouse core models
BI semantic models
dbt models
customer master data
employee or workforce data
inventory or supply chain data
AI-ready datasets
Related services
Metrics System Implementation
Before documenting metrics, it often helps to define what each KPI means, who owns it, and where it should come from.
Data Catalog Implementation
Once documentation is structured, we can move it into a searchable data catalog with ownership, glossary, lineage, and metadata.
Data Quality Monitoring
Documentation helps identify which datasets need quality checks, alerts, and ownership.
Data Governance Consulting
Governance keeps documentation alive by defining ownership, standards, and update workflows.
Data Documentation Services FAQs
What is data documentation?
Data documentation explains what data exists, what it means, where it comes from, how it is used, and who owns it. It can include dataset documentation, data dictionaries, dashboard documentation, metric definitions, business glossaries, and transformation logic.
What is the difference between a data dictionary and a business glossary?
A data dictionary describes technical data assets, such as tables, fields, columns, data types, and usage notes. A business glossary explains business terms and definitions in plain language.
Do we need to document every table?
No. Most teams should not start by documenting everything. It is better to begin with the datasets, dashboards, and metrics that matter most to reporting, decisions, and data quality.
Can you document our dashboards?
Yes. We can document dashboards and reports, including purpose, users, metrics, source data, refresh logic, ownership, and known limitations.
Can this work support a future data catalog?
Yes. In many cases, documentation is the preparation step before data catalog implementation. It gives the catalog useful business context instead of just technical metadata.
Where should data documentation live?
It depends on your stack. Documentation can live in a data catalog, BI tool, dbt docs, Confluence, Notion, SharePoint, GitHub, or another internal knowledge base. The best place is where your team will actually use it.
How do you stop documentation from going out of date?
We define ownership, review cadence, update rules, and documentation standards. The goal is to make documentation part of normal data work, not a one-off project.
Who is usually involved?
Usually the project involves the Head of Data, Analytics Lead, BI Lead, data analysts, analytics engineers, data engineers, and business owners for key metrics or reports.
