Data Warehousing & Modernization
Your data lives in a dozen places. The ERP, the CRM, spreadsheets on shared drives, a SQL database someone built ten years ago. Every report starts with a scavenger hunt, and every meeting starts with a debate about whose numbers are right.
A modern data warehouse ends that. We bring your data together in one governed place, model it around how your business actually works, and make it ready for reporting, automation, and AI.
Sound familiar?
• Month-end reporting takes days of exports and copy-paste.
• Two departments pull the same metric and get two different answers.
• Your warehouse runs on an on-premises SQL Server nobody wants to touch.
• The one person who understands the ETL jobs is thinking about retiring.
• You want to use AI, but your data isn't clean or connected enough to trust it.
What we do
Data warehouse design
We design dimensional models around your business processes, not your source systems. The result is a structure your team can understand and your reports can rely on.
Legacy modernization
We move aging on-premises warehouses, SSIS packages, and Access databases to Microsoft Fabric and Azure, without losing the history and business logic you've built up.
Lakehouse & Microsoft Fabric
We set up Fabric lakehouses and warehouses that handle structured and unstructured data in one platform, with Power BI built right in.
Data governance and quality
We set up Fabric lakehouses and warehouses that handle structured and unstructured data in one platform, with Power BI built right in.
Migration from sunsetting systems
Moving off Dynamics GP or another legacy platform? We preserve your historical data in a warehouse so you can retire the old system and still report on the past.
THE LEAF APPROACH
How we put Data Over Design into practice
We use a consistent, strategic approach for each project we tackle — and it starts with your data, not a wireframe.
- Assess. We inventory your sources, reports, and pain points, then score what to keep, fix, or retire.
- Model. We design the warehouse around your business entities and KPIs before writing a single pipeline.
- Migrate. We move data and logic in phases, validating every table against the source.
- Enable. We train your team, document everything, and hand you a platform you own.
What you get
• One version of the truth for finance, operations, and leadership
• Reports that refresh on schedule instead of by hand
• Lower infrastructure and maintenance costs than on-premises servers
• A foundation ready for Power BI, automation, and AI
Why Leaf
We've been building business systems since 1987. We know the ERP, CRM, and financial systems your data comes from, because we implement them too. That means your warehouse reflects how your business runs, not just how your tables are named.
FAQ

Fabric is Microsoft's unified analytics platform that combines data engineering, warehousing, and Power BI. It's a strong fit for organizations already on Microsoft 365 and Power Platform. We'll tell you honestly if a simpler option fits better.
Most start with a 2–4 week assessment. Delivery is phased so you see value early.
Yes. We often build alongside internal staff and leave them fully able to run and extend the platform.
