For example, at telecom company Verizon, the service called "get CSR" (get customer service record) is a complex jumble of software actions and data extractions that uses Verizon's integration infrastructure to access more than 25 systems in as many as four data centers across the country. Before building the "get CSR" service, Verizon developers who needed that critical lump of data would have to build links to all 25 systems—adding their own links on top of the complex web of links already hanging off the popular systems. But with the "get CSR" service sitting in a central repository on Verizon's intranet, those developers can now
use the simple object access protocol (SOAP) to build a single link to the carefully crafted interface that wraps around the service
>. Those 25 systems immediately line up and march, sending customer information to the new application and saving developers months, even years, of development time each time they use the service.
