A data warehouse is a technique for collecting and managing data from varied sources to provide meaningful business insights. It is a blend of technologies and components which allows the strategic use of data.

Data Warehouse is the electronic storage of a large amount of information by a business that is designed for query and analysis instead of transaction processing. It is a process of transforming data into information and making it available to users for analysis. (Source: guru99)

What Is Data Mining?

Data mining is looking for hidden, valid, and potentially useful patterns in huge data sets. Data Mining is all about discovering unsuspected/ previously unknown relationships amongst the data.

It is a multi-disciplinary skill that uses machine learning, statistics, AI and database technology.

The insights extracted via Data mining can be used for marketing, fraud detection, and scientific discovery, etc.

Data Mining Vs Data Warehouse: Key Differences

Data Mining Data Warehouse
Data mining is the process of analyzing unknown patterns of data. A a data warehouse is a database system which is designed for analytical instead of transactional work.
Data mining is a method of comparing large amounts of data to finding right patterns. Data warehousing is a method of centralizing data from different sources into one common repository.
Data mining is usually done by business users with the assistance of engineers. Data warehousing is a process which needs to occur before any data mining can take place.
Data mining is considered as a process of extracting data from large data sets. On the other hand, Data warehousing is the process of pooling all relevant data together.

Moreover, data mining tools work in different manners due to different algorithms employed in their design. In Data warehouse, data are pooled from multiple sources. The data needs to be cleaned and transformed. This could be a challenge.
The data mining methods are cost-effective and efficient compares to other statistical data applications. Data warehouse’s responsibility is to simplify every type of business data. Most of the work that will be done on the user’s part is inputting the raw data.
Another critical benefit of data mining techniques is the identification of errors which can lead to losses. Generated data could be used to detect a drop-in sale. Data the warehouse allows users to access critical data from the number of sources in a single place. Therefore, it saves the user’s time of retrieving data from multiple sources.
Data mining helps to generate actionable strategies built on data insights. Once you input any information into the Data warehouse system, you will unlikely to lose track of this data again. You need to conduct a quick search, helps you to find the right statistic information.
