Data Warehousing and Data Mining in Detail

Data warehousing refers to a typical procedure of compiling and organising data into a common database. On the other hand, data mining basically refers to the process of extracting useful data from various databases.

Please note that the data mining procedure entirely depends on the data that is compiled within the data warehousing phase. This helps in recognising all the meaningful patterns of the data. In fact, data warehousing is formulated to provide aid to management systems.

This in-depth guide to data warehousing and data mining will give you valuable insights into the features, applications, and more. Please keep reading until the end of the article to learn about the benefits, differences, and other things associated with data mining and warehousing. Let’s find out!

What is Data Mining?

In the process of data mining, data is carefully extracted and analysed to fetch nothing other than useful information. Here, all the hidden patterns are researched from the dataset, thereby predicting future behaviour. Besides, it can seamlessly indicate and discover unique relationships through the data.

On the other hand, data mining makes the best use of artificial intelligence, statistics, machine learning systems, databases, etc. It is used for figuring out the hidden patterns within the data. Additionally, it also supports all business-related queries that take loads of time to resolve.

A data warehouse is nothing but an electronic storage that stores gigantic amounts of business information. It is exquisitely designed for both query and analysis rather than processing transactions.

Data warehousing is a unique technique that helps collect and manage data from various sources. Furthermore, these data provide meaningful and valuable business insights. It is basically a blend of components and technologies that enables strategic usage of data.

In a nutshell, data warehousing is a process of transforming data into information, thereby making it widely available for analysis. Now, let us discuss the important differences between data mining and data warehousing in detail.

Features of Data Warehouses

Here is a comprehensive listing of the most common features of data warehouses:

1. Unified

Numerous heterogeneous sources are compiled together to formulate a data warehouse like social databases, level documents, etc.

2. Subject Oriented

It offers the most important data regarding particular subjects like products, suppliers, customers, promotions, etc. It handles data analysis and modelling while assisting organisations in making data-driven decisions

3. Nonvolatile

The previous data remains intact whenever new data is added to the data warehouse. Since the operational database and data warehouse are kept separately, changes within the operational database aren’t shown.

4. Time-Variant

Data collected within the data warehouse is seamlessly identified within a particular period.

Features of Data Mining

Some of the unique features of data mining are:

• It is capable of predicting future results
• It can efficiently handle large datasets and databases
• It can seamlessly utilise the automated discovery of patterns
• It has the potential to create actionable insights, etc.

Applications of Data Mining

The applications of data mining include:

• Research
• Education Sector
• Transportation
• Market Basket Analysis
• Business Transactions
• Intrusion Detection
• Scientific Analysis
• Finance and Banking Sector
• Insurance and Healthcare
