Data warehouse

A data warehouse works like a giant digital library that stores all of your company's data in one place. While regular analytics tools might only keep a few months of data, a data warehouse can store years of information about how customers use your product, what they buy, and how they interact with your business.

Modern cloud data warehouses like Snowflake, BigQuery, or Redshift can handle massive amounts of information and analyze it quickly. Imagine a clothing store that saves every purchase, every website visit, and every customer interaction from the past five years. Their teams can look through this data to answer questions like "What products sell best each season?" or "Which customers are likely to return for another purchase?"

The real power comes from connecting different types of data together. A company might discover that customers who contact support in their first week are more likely to become loyal buyers if they receive quick help. This insight helps teams make better decisions about where to focus their efforts.
