2. Generative AI-Powered Self-Service Analytics
Generative AI builds on the manual model but adds a powerful layer of intelligence. The semantic layer remains essential, as it allows AI to understand and interpret data consistently. But the magic happens next. With technologies like Natural Language Processing (NLP) and Large Language Models (LLMs), GenAI can interpret user questions and turn them into actionable insights.
Imagine typing: “How does product sales compare to last year?” AI understands the question, including the timeframe and product context, and converts it into a query. It pulls the right data from the semantic layer, analyzes it using advanced models, and presents results in a natural, easy-to-read format, complete with visuals like charts or dashboards. No need to be a data expert.
Examples: Power BI’s Q&A Visual and Tableau’s Ask Data are early examples of this in action.
But be careful: AI takes your question literally. If it’s too vague or broad, the answer might miss the mark. A critical mindset is still essential.
Example:
A marketer wants to evaluate the performance of a recent campaign. The semantic layer helps AI identify and link relevant data. It generates multiple visualizations, like a bar chart of regional sales performance, and the marketer selects the most insightful one to continue the analysis.
