Another very important subject related to data is, of course, data mining. Instead of data warehousing, which works on all the process from storing the data to de presentation, data mining focus is the analysis of information itself.
Throught this examination of information, the data is extracted and transformed in some usable data blocks. This process is largelly applied these days, in almost every industry that works and stores some information.
As we said before, this computer science concept is largelly used in data industry. Specifically in business intelligence systems or artificial intelligence ones, using techniques like machine learning, statistical analysis and others.
It is based on some data system, likely a database, and involves various data management methods. To gather more detailed information about databases systems, start by reading this basic database tutorial.
Define Data Mining
This computer science targets large sets of data and tries to discover patterns, with specific methods and algorithms, providing a much better understanding of that information. These patterns help to explore the data and detect relacionships between variables. Then, these patterns are applied to new data, validating it.
There are three basic stages of a data mining process:
- Pre-processing – Assemble a large set of information and analyse it, cleaning the bad data.
- Data Mining – Processing of data. Take use of the following methods: association, clustering, classification, regression and summarization.
- Validation – Verifying the discoveries and results.
These general tasks can be divided into more detailed subtasks, as we explore each subject.
Important Reading on Subject
In order to provide an intoductionary level document for the data mining subject, we developed a review of the best data mining books, we suggest to become an expert on the matter.
The previous books have distinct focus ideas, specific to data mining in multiple platforms and languages. Reading them will provide you a solid knowledge of how data mining is processed. Despite that, we suggest practical exercises by mining aa large set of data to consolidate all the information read in these books and other kind of sources.
