Generate report of all the information in a Web Application

I am working on a Web Application that sells a Product to users. I would like to create a count of all the times a user buys a product or when the user clicks on a product and doesn't buy it. I want to generate daily, monthly and annual report of this data so that I could eventually analyze this data. How should i approach this problem?. Are there any tools or third party applications that i can use to generate these reports?
