A business organization has to deal with a massive amount of data streaming from myriad sources, and data warehousing refers to the process of collection and storage of that data that needs to be analyzed to glean valuable business insight. Data warehousing plays a crucial role in business intelligence. The concept originated in the 1980s, it basically involves data extraction from disparate sources which later gets processed and post formatting the data stays in the system ready to be utilized for taking important decisions.
Data warehouse basically performs the task of running an analysis on the stored data which could be both structured and unstructured even semi-structured, however, the data that is in the warehouse cannot be modified. Data warehousing basically helps companies gain insight regarding factors influencing business, and they could use the data insight to formulate new strategies, developing products and so on. This highly skilled task demands professionals who have a background in Data science using python training.
What are the different steps in data warehousing?
Data warehousing involves the following steps
Transactional data extraction: In this step, the data is extracted from multiple sources available and loaded into the system.
Data transformation: The transactional data extracted from different sources need to be transformed and it would need relating as well.
Building a dimensional model: A dimensional model comprising fact and dimension tables are built and the data gets loaded.
Getting a front-end reporting tool: The tool could be built or, purchased, a crucial decision that needs much deliberation.
Benefits of data warehousing
An edge over the competition
This is undeniably one benefit every business would be eager to reap from data warehousing.
