Easily load data from all your sources to your desired destination without writing any code using Hevo. Deriving actionable insights from data and making them part of the business decision-making process is a key ingredient to success for businesses in modern times. This is made possible by sophisticated data platforms that accumulate data from various sources and analytics teams that dig through this data to derive insights. Data Warehousing and Data Mining are two integral parts of this data-driven decision-making approach.
Data Warehousing deals with having unified storage for all kinds of data in an organization. This requires data from various aspects of the business to be formatted into a form suitable for analysis and easy access. Once the data is in such a format, analysts or automated pattern matching algorithms dig through the data to derive insights. This process is called Data Mining. This article will help you understand the key differences between Data Warehousing and Data Mining.
These data sources could be the Databases of various Enterprise Resource Planning ERP systems, Customer Relationship Management CRM systems, and other forms of Online Transactional Processing OLTP systems.
