A data warehouse is a centralized repository of integrated data from one or more disparate sources, organized in a way that facilitates reporting, analysis, and decision-making. The purpose of a data warehouse is to provide a unified and comprehensive view of an organization's data, which can be used to support business intelligence and analytics.
Data warehouses are designed to handle large volumes of data and complex queries, and they often store historical data that can be used to identify trends, patterns, and insights over time. They are typically optimized for read-intensive workloads, and they often use specialized techniques such as columnar storage and indexing to improve query performance.
