Many organizations use ad hoc tools like spread sheets and wikis to keep track of their APIs. The API Catalog 12c may allow organizations to replace these tools with an online catalog that provides visibility to their APIs for application development. The API Catalog is a...

OAC provides a layer of visibility to those APIs so application development knows what and which one to use.  OAC includes a simple metamodel for an API asset, automation to populate OAC, and the ability for users to search OAC for APIs and understand the details of the APIs to assess their fit in the user’s...

The validation of required fields in web applications is important, and you have to do the same for mobile applications.

As you build the application, you will add MAF layout components to further control and customize the behavior of the application. In Part 2 of the tutorial, you add specific device integration to your application. In Part 3, you add a...
