title: How can I start with data mining for small grocery shop
body: <p>My company got the project to build simple website of grocery shop with catalogue only without shop cart. Few days ago I read something about data mining from <a href="http://www.anderson.ucla.edu/faculty/jason.frand/teacher/technologies/palace/datamining.htm" rel="nofollow noreferrer">here</a></p>
  
  <p>I found that it is possible to do some predictive modelling like</p>
  
  <p>For example, one Midwest grocery chain used the data mining capacity of Oracle software to analyze local buying patterns. They discovered that when men bought 
  diapers on Thursdays and Saturdays, they also tended to buy beer.</p>
  
  <p>I told them this example and they were happy if I can do something like that.</p>
  
  <p>Now don't know how to start and where to start. I know mysql database and can program complex queries as well. But I don't know how i can get the type of data like beer and diapers</p>
  
  <p>I have 3-4 months left. Can anyone guide me how i can start.
  I also don't know what type of data of customer shopping i can get from the shop may be excel files .</p>
  
  <p>But i want to start</p>
