What is Data Mining?
It is also known as Knowledge discovery or data discovery. As we all know that many large organizations are operated in different places and each place generates large volumes of data (a form of tera- to petabytes) and it is necessary for the companies to make decisions from all such sources to take a strategic decision. To analyze, manage and to make quick decisions we need to transform in all domains. The method of extracting useful information from a repository of data is called data mining. They focus on the data-driven discovery respectively. This tasks can be categorized into two ways they are: Predictive and descriptive. To process the petabytes of data mining data requires supercomputer and computing clusters. Types of data mining include Supervised and unsupervised learning.
It is a powerful technology with great potential to extract hidden predictive data/Patterns from the large repository (Databases, text, images) that uses scientific methods, algorithms to extract knowledge of data (a type of data is structured) in different forms. It is an analytical process to explore a large amount of data by applying detective patterns to those data to get new subsets of data to improve business process and decision making.
Understanding Data Mining
Mining is typically done on a database with different data sets and is stored in structure format, by then hidden information is discovered, for example, online services such as Google requires huge amounts of data to advertising their users, in such case mining analyses the searching process for queries to give out relevant ranking data. The tools and techniques used in mining process are classifications (predict most likely case), Association (identifying variables related to each other), prediction (predict the value of one variable with the other). For good Pattern recognition, it makes use of Machine learning. A wide variety of algorithms are implemented to take relevant information from the queries.
How does Data Mining make working so easy?
They make the work so easy by predicting customer behavior and uses these tools to search patterns of data. It turns raw data into structured information. The steps involved in this process are:
- They extract and load data into a data warehouse (which requires pre-processing) which are stored in the multidimensional database (which does slice, dice, cubical format analysis).
- Using Application software, they provide data access to business analyst.
- Presenting this information in an easily understandable format such as graphs.
- Need to increases the volume and diversity of data.
In short, we can say it works in three simple steps. They are data preparation(exploration), choosing various models for building and validation, Deployment stage(generate expected outcomes). On the other side, it is not as simple to work as it is essential for the data mining to understand what and how it can be implemented in all the streams of data with respective of massive production of data around the organizations. Examples of data mining include e-commerce, Customer Relationship Management, Banking, Health Care, Primary essential in Marketing. In all these applications datamining Algorithms are applied to prepare predictions and to extract patterns of data.
