Goal is to Access Enterprise Data on a Company Mobile App What are the Major Challenges? How to secure the data? How to create and manage new roles and access for new types of users – who are now seeing some enterprise data – maybe for the first time How to access the data? What protocols – SOAP or REST or Proprietary or Security must be applied to message being sent, & what if it changes? How to consume the data? Format – XML or JSON How much to consume – where does the data get filtered, mapped, sorted, computed, before display on the mobile device? So, how do I get the data into the user interface?

Consuming Enterprise Data Services Can Be Too Much for Mobile Applications Needs to Display: Current Balance Data Services Shaped Data Service Payload Contains Complete Customer Account Info: Customer First Name Customer Last Name Email Phone numbers Addresses … Current Balance Transactions

Consume REST Services in Oracle Front-end Development Tools Mobile: Java: Application Development Framework (ADF) Desktop, Mobile ADF (MAF) JavaScript: JavaScript Extension Toolkit (JET), Application Express (APEX) Desktop: ADF JET APEX Oracle Forms

Create RESTFul Web Services in Oracle Application Express (APEX) Same functionality as ORDS – but developed and available within APEX as well, uses APEX UI and Capabilities – ORDS can be programmed or managed with SQL Developer or CLI.

Oracle Application Express (APEX) Solution About Oracle REST Data Services Oracle REST Data Services is a JEE-based alternative for Oracle HTTP Server (OHS) and mod_plsql. The JEE implementation offers increased functionality including command line based configuration, enhanced security, file caching and RESTful Web Services. Oracle REST Data Services also provides increased flexibility by supporting deployments using Oracle WebLogic Server, Oracle Glassfish Server, Apache Tomcat, and a standalone mode. The Oracle Application Express architecture requires some form of Web server to proxy requests between a Web browser and the Oracle Application Express engine. Oracle REST Data Services satisfies this need but its use goes beyond that of Oracle Application Express configurations. Using Oracle REST Data Services simplifies the deployment process because there is no Oracle home required as connectivity is provided using an embedded JDBC driver. See Oracle REST Data Services Installation, Configuration, and Development Guide for concepts and details. select * from customers where cust_id = :id <Course name> 1 - 13

Oracle Mobile Cloud Service: Mobile Back Ends Mobile back ends are server-side groupings of APIs and other resources that you create to support a specific set of applications. MCS is a cloud-based service that provides a unified hub for developing, deploying, maintaining, monitoring, and analyzing your mobile apps and the resources that they rely on. Connecting to and accessing MCS services will be covered in a later lesson. Develop Mobile Front Ends Using Mobile Application Framework 5 - 14

Oracle Mobile Cloud Service Custom APIs Mobile Connectors Platform APIs REST APIs Diagnostics Analytics Lifecycle Node Notifications Storage Database Data Offline Mobile Back End Life Cycle User Services MAF Application Oracle Cloud Overall, MCS has two sets of APIs that can be published to the outside world through the MCS mobile back ends: custom APIs and platform APIs. Custom APIs coded in Node.js give you the flexibility and freedom to build practically whatever services you want for your mobile applications. Using Node.js, you can expose, shape, and customize any of your existing enterprise system services specifically optimized for your mobile applications to consume. In contrast, platform APIs are a set of built-in APIs provided by MCS to give your mobile team a boost by providing common services and APIs typically required by mobile applications, such as push notifications, data synchronization, storage, and analytics. It’s these platform APIs that specifically make MCS valuable to mobile teams— these are a key value proposition for MCS, saving your teams from having to write, test, and maintain this code themselves. In context of the platform APIs, these are available as REST services, which mean they can be very easily called from your consuming mobile applications. However, to make this simpler, MCS ships with a native mobile platform SDK. This SDK makes calling the MCS REST services easier because it removes the need to write a large amount of code to call the REST services, instead replacing this code with SDK calls in the mobile’s native language, such as Objective C for iOS and Java for Android, in typically nothing more than one or two or three lines of code.

Summary Mobile applications have very different data needs than internal desktop applications. Mobile apps require RESTFul web services to provide shaped data payloads of smaller sizes.
