Melania is a government web developer who recently created a public application that offers property records. She would like to make it available for other developers to integrate into their applications. What can Melania create to make it easiest for developers to call her code directly and integrate the output into their applications?

While Melania may certainly use an object model, data dictionary, and primary key in her development effort, external developers cannot directly use them to access her code. An application programming interface (API) allows other developers to call Melania's code from within their own without knowing the details of Melania's implementation.
