A Data Warehouse (DW) is the central, integrated repository for historical and current data, optimized exclusively for reporting, business intelligence (BI), and analytical querying.

A Data Warehouse is the foundational system for enterprise analytics, consolidating data from disparate operational sources (OLTP systems) into a single, structured source of truth. Data is prepared via Extract, Transform, Load (ETL) or ELT processes, ensuring it is clean, consistent, and time-variant before storage. Unlike transactional databases, the DW is optimized for complex, high-volume analytical queries (OLAP) using columnar storage and Massively Parallel Processing (MPP) architectures. Modern cloud platforms like Snowflake, Amazon Redshift, and Google BigQuery exemplify this technology, offering elastic scalability and pay-as-you-go models for fast, data-driven decision-making across the organization.

### [Proactive agents that learn from user behavior](https://amsterdam.aitinkerers.org/talks/rsvp_OIXfXSDJe8Q)

For my startup https://donethat.ai I have an agent that can do two things: Send people a daily email and open a chat window proactively. Both are very high risk because as soon as people get annoyed they'll disable that channel forever. To prevent this, I built a system that monitors user response and adjusts behavior based on this.

### [Unlocking Insights from Tabular Data with LLMs](https://toronto.aitinkerers.org/talks/rsvp_EVqtcfX0ujE)

This application demonstrates how we can leverage Large Language Models (LLMs) to extract valuable insights directly from your company's tabular data. Unlike unstructured data (PDFs, Docs etc.) that require Retrieval-Augmented Generation (RAG) techniques, this approach allows LLMs to interact with structured data in a more efficient way. Here's how it works: Natural Language Understanding with LLM: The user submits a question in plain text. The LLM parses this question to understand its intent and the relevant data points needed. SQL Query Generation: Based on the understanding, the LLM generates a corresponding SQL query to retrieve the desired information from your company's data warehouse. Data Retrieval and Summarization: The generated SQL query is executed, fetching the relevant data points. Finally, the LLM summarizes the retrieved data in a clear and concise manner, providing a comprehensive answer to the user's initial question.
