Deep Dive
What is the primary challenge in data governance according to Sarah Levy?
The biggest challenge is that business leaders often cannot trust the numbers reported by their data products, despite significant investments in data tools and teams.
What is a semantic layer in the context of data governance?
A semantic layer is a centralized store for certified definitions of calculations and metrics, providing a single source of truth for data context and ensuring consistency across an organization.
Why is a semantic layer important for organizations?
It ensures consistency and alignment across an organization by providing a central source of truth for metrics, which is crucial for trust in data-driven decisions and for training AI tools.
What are the main steps in implementing a semantic layer?
The steps include curating and mapping metrics, resolving inconsistencies, coding them, and building a workflow to maintain the layer over time.
Who needs to be involved in creating and maintaining a semantic layer?
Business analysts, data engineers, and analytics engineers are all involved. Business analysts define the logic, analytics engineers implement it, and engineers ensure it is coded and governed properly.
What is the role of analytics engineers in data governance?
Analytics engineers bridge the gap between business and data teams, owning the semantic layer and ensuring it is well-architected, coded, and maintained.
How does AI impact the role of analytics engineers?
AI tools require a governed semantic layer to function effectively, making analytics engineers critical for implementing and maintaining the layer that AI models rely on.
What is a governance score and why is it important?
A governance score measures how much of an organization's data assets rely on governed metrics and tables. It helps organizations understand how much they can trust their data and where improvements are needed.
How should organizations prioritize which metrics to govern first?
Organizations should prioritize metrics and dashboards that are highly utilized or where significant resources are invested, as these are indicators of high business value.
What is the relationship between a semantic layer and AI-driven analytics?
A semantic layer is essential for enabling AI-driven analytics by providing a certified set of definitions that AI tools can use to generate trustworthy insights.
How can data governance encourage innovation while maintaining control?
Governance should allow analysts to create and experiment freely in their preferred tools, while observability tools identify which creations gain traction and should be added to the semantic layer.
What is Sarah Levy's mission with her company, Euno?
Her mission is to help large-scale data teams easily understand and derive value from their data by facilitating the creation of a central governed semantic layer and enabling AI adoption.
