What is Data Warehousing?
Data warehousing is a technique used in business intelligence to store and analyse large volumes of data from various sources in a central repository.
Data warehousing aims to provide a single source of truth for an organisation's data, allowing for more efficient and accurate decision-making.
Data warehousing typically involves using specialized software and hardware to extract, transform, and load (ETL) data from disparate sources into a central repository.
The data is then organized and stored to allow for efficient querying and analysis using tools such as data mining, reporting, and dashboards.
One of the key advantages of data warehousing is the ability to perform complex analysis on large volumes of data quickly and efficiently.
This can be particularly useful for businesses that generate a large amount of data, such as e-commerce companies or financial institutions.
Data warehousing also helps to eliminate data silos and inconsistencies, allowing for better collaboration and decision-making across departments.
