The three social networks -- Twitter, Facebook and LinkedIn -- are basically communication forums each to a different set of people. On Twitter you are putting out your information and ideas in a very succinct manner and normally people don't hide their timelines. On Facebook you can choose to communicate with all people with internet access or to your friends or to a subset of friends, as you can control the privacy settings on each individual update. LinkedIn is the means to communicate with all your professional contacts.

In this post, I discuss a basic data analysis example using core Java. Consider a bank which has presence in 50 districts having 10,000 accounts in each district. The balance in each of those 500,000 account is available say, in a text file. The bank manager is interested in finding, "In every district what are the three accounts with the largest balance?"

I was playing with Glen Mazza's DoubleIt example application which he presented in his blog post "Creating a WSDL-first web service with Apache CXF or GlassFish Metro". I wanted to make just a couple of changes, re-run the example and be done with it. Then, one thing lead to another and I converted it to a wholly different application, which I have named as MyBankPortal application Now I am thinking more. Using it as a base application, I would add more applications around it and have a sample integration scenario. Thus it will be a tutorial to more than on technology. MyBankPortal itself would have more and more functionality to illustrate various technical features. All this in due course of time.
