Enter the data warehouse, to provide some level of standardisation and a focus on analytics. In the 1990s, the data warehousing concept, championed by Bill Inmon (3NF), and Online Analytical Processing (OLAP), popularized by Ralph Kimball, took centre stage. Both were an attempt to make this easier, and faster, getting fat into the hands of those that need it. Data warehouses promised a centralized repository for all data, breaking down the silos created by Data Marts. Installing a concept of a single source of truth. Likewise, OLAP enabled more complex queries and analysis, in a business context, enhancing business intelligence capabilities.
