why we need and require data warehouse?
A data warehouse is a type of data management system that is designed to enable and support business intelligence (BI) activities, especially analytics. A data warehouse is a central repository that stores structured data (such as database tables or Excel sheets) and semi-structured data (such as XML files or webpages) from various sources for the purposes of reporting and analysis. A data warehouse usually contains large amounts of historical data that can be used for data mining, data visualization, and other forms of BI reporting. A data warehouse can also provide a single source of truth for an organization by consolidating and integrating data from different sources and ensuring its quality and consistency¹²³⁴.

Some of the benefits of using a data warehouse are:

- Improved data quality and consistency: A data warehouse can help eliminate data silos, redundancies, errors, and inconsistencies that may exist in different data sources. It can also help standardize and integrate data from various sources into a common format and structure that can be easily accessed and analyzed.
- Enhanced data analysis and reporting: A data warehouse can help provide a comprehensive and historical view of the data that can support various types of analysis and reporting, such as descriptive, diagnostic, predictive, and prescriptive. It can also help enable faster and easier data exploration, discovery, and visualization using various BI tools and applications.
- Increased business intelligence and decision-making: A data warehouse can help deliver valuable insights and information that can help improve business performance and competitiveness. It can also help support strategic, tactical, and operational decision-making by providing timely, accurate, and relevant data to the end-users, analysts, and decision-makers.
- Reduced costs and risks: A data warehouse can help reduce the costs and risks associated with data management, storage, processing, and security. It can also help optimize the use of resources and improve the efficiency and effectiveness of business processes
