Data Warehousing
Data warehousing is the process of collecting, storing, and managing data from various sources to support business intelligence activities such as data analysis, reporting, and decision-making. It involves the extraction of data from different sources, transforming it into a consistent format, and loading it into a centralized repository. Data warehousing enables organizations to access and analyze large volumes of data from multiple sources, providing a comprehensive view of their business operations. It also helps in identifying trends, patterns, and relationships in data that can be used to make informed decisions. Data warehousing involves the use of various technologies such as ETL (Extract, Transform, Load), data modeling, and OLAP (Online Analytical Processing) to manage and analyze data effectively.
