Enterprise Data Migration + Source-of-Truth Architecture
HCG defined a source-of-truth and migration architecture that separates wholesale, retail, and order records from spreadsheet views, calculations, API references, temporary imports, and reporting logic.
Primary reader question: How should a business move operational records from spreadsheets into a controlled source-of-truth database?
What this HCG project established
HCG established which tables own business records, which spreadsheets remain governed views, how QuickBooks Online and HubSpot data connect, and what validation, history, and reconciliation are required before database migration.
The condition that required a controlled system response
Operational spreadsheets had evolved into a mixture of source records, derived views, assembly logic, and external references. That made migration risky because the visible workbook structure did not clearly reveal which data was authoritative.
Constraints that governed the work
- Preserve business continuity while data models are redesigned.
- Separate core records from calculated or presentation-only tabs.
- Reconcile identifiers across QBO, HubSpot, orders, wholesale, and retail data.
- Create instructions detailed enough for later implementation in a coding environment.
Why this work matters beyond the technology.
Clarifies which system owns each core record and prevents multiple files from silently competing as the source of truth.
Preserves validation, identifiers, calculations, history, and external-system relationships during migration.
Allows spreadsheets to remain useful analysis and operating views without carrying the full risk of database, workflow, and integration responsibilities.
How the work was structured to reduce uncertainty and execution risk.
- 01
Classify each table as source, derived view, assembly, or external reference.
- 02
Define canonical records and relationships for wholesale, retail, and orders.
- 03
Inventory API-sourced fields and synchronization responsibility.
- 04
Stage migration through data dictionary, validation, schema, test import, reconciliation, and cutover gates.
What the system contains and how the parts work together.
A target relational data model and migration sequence.
Clear ownership rules for records and derived views.
Integration boundaries for QBO and HubSpot.
Validation and reconciliation requirements before production cutover.

What is materially different because of the work
The statements below reflect the documented project state. They do not convert an active, defined, or conceptual project into a completed implementation or claim unsupported financial results.
- The migration scope now distinguishes the actual database entities from the spreadsheets that display or assemble them.
- External API data is treated as governed integration input rather than copied spreadsheet content.
- The project has a staged path for moving from planning into coded implementation.
Artifacts that can substantiate the work
Public evidence depends on client permission and confidentiality. HCG can use approved public, controlled, or anonymized artifacts without presenting confidential material as open proof.

What business problem does Data Migration Architecture address?
HCG established which tables own business records, which spreadsheets remain governed views, how QuickBooks Online and HubSpot data connect, and what validation, history, and reconciliation are required before database migration.
What did Hinson Consulting Group create or define?
The defined solution includes the following components: A target relational data model and migration sequence; Clear ownership rules for records and derived views; Integration boundaries for QBO and HubSpot.
What is the current status of Data Migration Architecture?
Active development. The project is in active development; implemented and planned elements are distinguished in the documented current state. The migration scope now distinguishes the actual database entities from the spreadsheets that display or assemble them. External API data is treated as governed integration input rather than copied spreadsheet content.
Lessons carried into future HCG and CREVOX work
- A workbook is a user interface, not necessarily a data model.
- Migration begins with ownership and definitions, not with copying cells into tables.
- External-system records require identifier, refresh, error, and reconciliation rules.
