This term may sound familiar, but what is really known about data warehousing? Data warehousing refers to the capture of data from diverse sources for useful analysis and access into a database. In simple words, data warehousing solutions collect information from different sources in the internet and store them in a personalised database. These pieces of data can be used anytime to analyse customers’ behaviour, browsing habits, and digital market trends.
This is the era of Big Data and Data Analytics. Yet these massive amounts of information need to be stored and organized accurately for easy access at any time. Data Warehouses are the perfect solution for this. A Data Warehouse is a digital collection of corporate information and data derived from operational systems as well as external data sources. That is, it is a server application which houses all forms of big data and keeps the information secure for future access.
This is a relatively new concept though a lot has been spoken and a lot has been implemented using it. For a preview, a data warehouse (DW) is a collection of corporate information and data derived from operational systems as well as external data sources. It is different from a database. The purposes of data warehouses are to support business decisions by allowing data consolidation, analysis and reporting at different aggregate levels.
