What is Data Mining

We are drowning in data, but starving for knowledge!

Data mining is attempt to gain knowledge from masses of data. In other words, data mining is the process of discovering meaningful correlations, patterns, and trends by sifting through large amounts of data stored in databases.

Simple Data Mining Techniques

Data mining can simply be done by visualisation of the data through simple graphing and charting e.g. scatter graphs, but can also use sophisticated pattern recognition technologies as well as statistical and mathematical techniques.

See the following simple example - the size of the circles indicates the sales volume - the colour indicates the amount of discounting (more discount - deeper the red). A pattern can be seen that stores in West have been discounting predominately!

The use of basic statistics in the form of regressions and multiple regressions would be the next step up from graphing.

Typical applications for data mining

Here are some examples of data mining applications:

• Identify buying patterns from customers
• Find associations among customer demographic characteristics
• Identify `loyal' customers
• Predict customers likely to stop using your products
• Identify fraudulent behaviour
• Characterise patient behaviour to predict office visits or non attendance
