Web 2.0 applications are giving programmers access to theirinformation data stores and basic functions through simpleprogramming interfaces (API’s) based on service orientedarchitecture principles. A program’s content and functions can beexposed to other programs running on the web by “wrapping” themwith these API’s. There are really two common API standards 1. SOAP (simple object access protocol) 2. REST (representational state transfer).
