There is software behind every web application you see on the web. Softwares have become part and parcel of everybody’s life. There are two types of software. One is general software and the other is customized software. General software is aimed for a large part of the population and can be accessed by anybody. Customized software is developed by companies for particular applications/purposes. Like Oil Claim Calculator is a software that was used to calculate OVER 1 Billion Dollars in Deepwater Horizon Oil Spill claims in excess of 10,000 claimants that were submitted to the court-supervised DHECC. The customized software are supposed to work for particular applications and not meant for general purposes. They are mostly developed by companies which do not want to purchase expensive packages and get all the work done efficiently in an economical manner.
