When you use Data Federation to provide access to application data, you have several options.
For many applications, data can be made available to the data catalog without programming. Some applications that use relational data provide an interface with database views that can be accessed using SQL. Data from these sources can be made available via database operations. Data from many applications with HTTP interfaces can be made available by creating a data service that references the URL and granting access to it. Data from applications that have neither a database interface nor a URL-based interface, and that make data available only through a proprietary API, can be provisioned into Data Federation via data services.
