Web Services - Essay Example Service Oriented Architecture is an overly used and widely contextualized term that means different things to different people. Rotem (2007) examines the definitional edifice of SOA, and analyzes the term to derive its broader intended import. The Service Orientation component of the term SOA, addresses the enterprise, or the business perspective.

The Architecture component of SOA, defines the technical perspective. SOA is seen as an architectural style that is loosely coupled, interoperable, and built using components, or software agents called, services.

The lower- and middle-class feared that being obliged to purchase a healthcare plan will give much pressure on their limited resources, since they will not be qualified to the ‘low income pass’ (Planinz 2009, para 2) of President Obama. Also, conservative health supporters are discouraged that the plan of the president does not involve insurance for a lot of kinds of similar medicine (ibid, para 2). Backers of the healthcare bill of the president say that millions of Americans with no health insurance are now being a burden to the economy of the government (Haddy 2010). As said by National C oalition on Health Care, â€Å"The United States spends nearly $100 billion per year to provide uninsured residents with health services, often for preventable diseases or diseases that physicians could treat more efficiently with earlier diagnosis† (Planinz 2009, para 6).

Insurance companies looking for revenues will try to cover individuals who are not sickly. Employers and doctors will, with no payment rules, try to give the highest amount of service they can give for the maximum price (Kinney 2010). There are lots of facts saying that all individuals involved in healthcare will and do act in response to payer regulations intended to lessen costs. Individual suppliers and providers will act towards appeals to create profits without interests to public policy (Haddy 2010). Regulations are developed to lessen price and use.
