Top Data Mining tools

Introduction to data mining

The world today runs on data but the question remains: How are we sourcing this data? The answer to it is not very simple. Data is often extracted from several sources and then crunched into useful numbers which is then used by companies to make any particular decision. Data Mining refers to the set of techniques and methods which involve the use of multiple software for the extraction and finding of suitable data points. 

This involves a lot of research and brainstorming as suitable information has to be mined out of several sources. Data mining is not limited to finding out the sources of data. It majorly involves analyzing the existing databases for new insights as a particular sample set of data can give out a lot of new perspectives of looking at it. Data mining makes use of various statistics principles to trace the relationship between any two given data points. Also, in today’s era, it uses tools like machine learning and artificial intelligence to find out various patterns and trends which become difficult to do manually.

What can be achieved with data mining?

Data mining involves scrutinizing of raw data. This raw data can be anything like the price of a particular commodity at a particular point of time, the data on competitors, data on consumption pattern of a particular market segment, data on what marketing strategies have worked out well in a particular industry, etc. Data mining is also used for making business forecasts and predicting the uncertainties which envelop various business entities working in different sectors. 

Also, the trend analysis is one of the major benefits of data mining as these give out patterns which help in analyzing the data faster and better and also gives powerful insights for a better understanding of the consumer base and their behavior such as the purchasing pattern, the kind of goods in which the consumer likes to spend, consumption patterns, frequency of purchases made by the customer, etc. thus leading to a productive and curated strategy to be taken to handle a particular market. 

Also, with data mining, various hidden facts can be brought to the attention which will help the business in a lot of ways. For example: If a company is looking forward to entering a particular market segment, it would need a lot of information such as the size of the market, the size of the market which the company can tap, demand for that particular product in a particular area, etc. All this can be found out by hitting the eye and mining the correct and the most relevant data sources.

With the help of data mining, you avoid ambiguity and analyze data to extract information which is relevant to a particular business. With data mining, the operational costs can be brought done to a huge extent and with various automated tools available to mine data, the manpower cost has gone down drastically. 

Data mining techniques

The data can be mined by using several techniques such as:

  1. Statistics: Statistics deal with the collection and segmentation of data. Here, the quantitative aspect of data is being taken care of. This is an old technique that makes the trend analysis easy. Statistics bring various measures into the picture like regression, correlation, etc.

  2. Clustering: Clustering of data is one of the most primitive and important steps in mining data. By this technique, the data is segregated into similar chunks and is divided into various segments which are then analyzed independently and also compared to the other segments thus formed. 

  3. Visualization: The visualization of data is a very important aspect of data mining. You can mine a lot of information from a given set of data but it is of no use when the person for whom the information is meant for is unable to understand it. It sanitizes the data and converts it into an understandable form that serves the purpose of data mining.

  4. Decision Tree: Here, the data is arranged in the form of a tree showing the hierarchal and chronological relevance of different sets of data. Each branch of the tree is a classification and the data which supports the classification. This makes it easier for the user to make decisions and predictions.

  5. Association: This technique aims at finding various links between two different sets of data or between various classifications made in the same data set. It establishes a relationship between various variables thus extracting valuable information for analysis and implementation. 

  6. Neural Networks: This is a basic foundation step which is automated. The user does not have to put in a lot of effort into the mining of data using neural networks. It is easy to use. 

  7. Classification: This is one of the most popular techniques used in mining data. Here, there are predefined classifications and models which classify a big set of data. It also brings in the element of other techniques which makes the data mining process a lot easier.
