Practical insights on data strategy, governance, agentic workflows, and semantic layer architecture — for teams building serious data infrastructure.
Apache Parquet, Iceberg, Polaris, and Ossie now cover every layer of the data stack with open, vendor-neutral standards. Here is what each layer does, how they compose, and what it means for AI-ready data architecture.

OSI is now Apache Ossie (Incubating). The rename is cosmetic. The governance transfer to the Apache Software Foundation is the story — and what it signals for the semantic layer as infrastructure.

AtScale and dbt Semantic Layer both promise a single source of truth for metrics. But they represent two completely different architectural philosophies and serve two different organizational realities. Here is the head-to-head comparison that vendor demos will not give you.

Snowflake shipped Cortex Sense, CoCo Desktop, and CoWork at Summit 26. Cortex Sense is the context runtime that sits between the model and the data. Here is what each product does and why the three form a coherent agentic stack.

Snowflake announced Horizon Context at Summit 26: a unified active context layer sitting on Horizon Catalog, serving AI agents, BI tools, and the Cortex stack from one place. Here is what it actually is, and what it does to the OSI question.

Gartner formally warned that skipping semantic foundations will cause AI agents to hallucinate, waste budget, and create governance risk. Practitioners already knew this. Here's what the context layer is and what building it actually requires.

Evaluating Looker alternatives? The real decision is not which tool has better dashboards — it is what happens to your semantic governance layer when you switch. A vendor-neutral framework covering Omni, Lightdash, Sigma, Power BI, Metabase, Cube, and when NOT to leave Looker.

80-90% of Fivetran customers already used dbt. The merger formalized what most data stacks were already doing — but the implications for open source, the Iceberg bet, and the semantic layer are worth thinking through carefully.
Wesley Nitikromo· May 2
Text-to-SQL accuracy nearly doubled between 2023 and 2026. The semantic layer still wins on determinism. But the real question isn't which benchmark wins — it's an architecture decision about where your business logic lives.

How to get Snowflake Semantic View Autopilot working in production, not just in a demo. The decisions that matter, the limitations nobody mentions, and where SVA fits in your data architecture.

Omni raised $120M at a $1.5B valuation today — with the semantic layer as the explicit center of their pitch and their moat. Here is why the framing matters as much as the number.

Google announced the agentic BI era with Looker at Next '26: BI agents, a native MCP server, Gemini-powered LookML, and the Knowledge Catalog. Here is why I think this is the right move — and the one thing that still determines whether it works.

Snowflake Semantic Views are now the native semantic layer inside Snowflake, powering Cortex Analyst, AI agents, and BI tools from a single governed definition. Here is how to implement them correctly — including Autopilot, dbt integration, and the best practices that matter in production.
Wesley Nitikromo
When you run Tableau, Power BI, and Sigma simultaneously, every metric gets defined three times — and diverges. A semantic layer for multiple BI tools is the only architecture that fixes this without replacing any of them.
Wesley Nitikromo
Most BI migrations fail because teams migrate dashboards instead of fixing the logic underneath them. Here is a honest account of what works, what breaks, and why the semantic layer is where every migration should start.
Wesley Nitikromo
Most Sigma vs Looker comparisons debate visualizations and pricing. The actual decision is about the semantic layer — whether you need one, and where it should live relative to your BI tool.
Wesley Nitikromo
What does a semantic layer consultant actually do? When does it make sense to hire one versus building internally? And what makes an independent consultant different from the vendors pitching you tools? Here is the honest answer.

Most AI projects fail before the model is ever the bottleneck. The real problem is the data foundation underneath. Here is what it takes to build one that actually supports production AI.
Wesley Nitikromo
AI agents hallucinate on business data not because the model is bad, but because the data layer underneath it is non-deterministic. A technical breakdown covering SQL generation, text-to-SQL accuracy, caching, reconciliation, and monitoring.

dbt Semantic Layer and Cube are not interchangeable. One defines metrics. The other defines and serves them. This is the architectural difference that determines which one belongs in your stack.
Wesley Nitikromo
The only vendor-neutral comparison of the best semantic layer tools in 2026. No product to sell. Covers dbt MetricFlow, Cube, AtScale, Snowflake Semantic Views, Databricks Metric Views, LookML, and Omni — organized by architecture fit, not feature score.

75% of companies plan to deploy AI agents by end of 2026. Meanwhile, formal governance policies dropped from 45% to 37%. The problem is not the agents. It is what is underneath them.
Wesley Nitikromo· Apr 12
Meta deployed 50+ AI agents across their data pipelines. The lesson: AI only works when the data foundation is in place first.
Wesley Nitikromo· Apr 11
Google just reversed the Looker Studio rebrand, reinstating Data Studio for the free tool and keeping Looker exclusively for enterprise governed analytics. For those of us who spent years explaining LookML to confused clients, this is overdue.
Wesley Nitikromo· Apr 11
AI agent adoption surged 327% in four months. Yet 40% of agentic AI projects have been cancelled or paused, and agents keep failing. The bottleneck is not the model. It is the data infrastructure underneath it.
Wesley Nitikromo· Apr 10
An AI agent at a Fortune 50 company rewrote its own security policy. The fix is not better identity controls. It is a governed data foundation.
Wesley Nitikromo· Apr 9
Only 7% of enterprises say their data is completely ready for AI. The Cloudera and HBR 2026 report confirms what the 60% AI project failure rate has been screaming: the bottleneck is the data foundation, not the model.

Semantic interoperability enables different systems, tools, and AI agents to share business logic consistently. The Open Semantic Interchange (OSI) specification is the vendor-neutral standard making it happen across your entire data stack.
Wesley Nitikromo
Snowflake, Microsoft, dbt Labs, Salesforce, and Databricks all converged on the semantic layer as critical AI infrastructure within the same month. The Open Semantic Interchange spec is now the standard.
