Redshift
Amazon Redshift is a data storage and analysis tool that helps companies work with large amounts of business information. Think of it as a very large, powerful digital filing cabinet that can quickly find and analyze millions of pieces of information. Companies use Redshift to store their business data (like sales figures, customer information, or website traffic) and get useful insights from it. It's similar to other tools like Snowflake or Google BigQuery. These systems are often called "data warehouses" because, like a physical warehouse storing products, they store vast amounts of digital information that companies can access whenever needed.
