Answer:
data warehouse
Step-by-step explanation:
A data warehouse , also known as an enterprise data warehouse , is a system used for reporting and data analysis, and is considered as a core component of Business Intelligence environment. data warehouse are central repositories of integrated data from one or more disparate sources. They store current and historical data and are used for creating analytical reports for knowledge workers throughout the enterprise. In short, a data warehouse is a database organised in a way that is conductive to producing business analytics quickly and accurately. Relevant data is extracted from one or more operational systems and brought together in a single place (warehouse) to provide a business with a central store of data. Business intelligence (BI) is a process for analyzing data and deriving insights to help businesses make decisions. In an effective BI process, analysts and data scientists discover meaningful hypotheses and can answer them using available data. For example, if management is asking “how do we improve conversion rate on the website?” BI can identify a possible cause for low conversion. The cause might be lack of engagement with website content. Within the BI system, analysts can demonstrate if engagement really is hurting conversion, and which content is the root cause. The tools and technologies that make BI possible take data stored in files, databases, data warehouses, or even on massive data lakes—and run queries against that data, typically in SQL format. Using the query results, they create reports, dashboards and visualizations to help extract insights from that data. Insights are used by executives, mid-management, and also employees in day-to-day operations for data-driven decisions.
