Data Warehouse

What is a data warehouse?

A data warehouse is a centralized system that collects and stores structured data from various sources and makes it available in a standardized form. It is optimized for fast queries and analyses and serves as the basis for business intelligence applications. In contrast to a data lake, the data in a data warehouse is highly structured and prepared for specific analysis purposes.

Advantages and areas of application

The use of a data warehouse enables companies to make decisions quickly, as data is available in real time. It is often used in financial analysis, sales reporting and operational monitoring. The benefits include higher data quality, fast access times and the ability to create complex reports. Modern data warehouses often use cloud technologies to ensure scalability and cost efficiency.
