“The data layer is where most enterprise solution challenges originate — not because the data decisions were technically wrong, but because they were made too late, without enough information.”
Everything else in a solution can be adjusted after deployment. The data model cannot — without rebuilding. Getting the data layer right is the single highest-value investment a solution designer can make.
The Data Decision
Before the first flow is built, seven questions determine whether a solution will be governable, secure, and maintainable at the scale it will eventually reach. Where does the data live? What is its classification? Who has access — and at what level? How long is it retained? What audit trail is required? How will it be discovered in response to a data subject request? Who owns it when the builder moves on?
What Power Platform Provides
Microsoft Dataverse is the enterprise data foundation — with security roles, column-level security, row-level security, audit logs, and retention policies built into the structure rather than added as an afterthought. Microsoft Purview provides sensitivity labelling and data classification that extends across Dataverse, SharePoint, and every connected workload. Data residency configuration at the environment level ensures regulated data stays in the right geography.
The Enterprise Gap
The most common data governance gap is the default data layer choice. SharePoint lists work well for Tier 1 and Tier 2 solutions. They are not the right foundation for solutions handling Confidential data, requiring audit trails, or needing row-level security. The gap appears when the data layer choice is driven by familiarity rather than by the governance requirements of the solution.
One Action
For every new solution above Tier 1, make the data classification the first question. The answer determines the data layer, the environment tier, the Data Loss Prevention policy posture, and the security model. One question. Four governance decisions answered.
