This document discusses data caching strategies for Oracle Mobile Application Framework (MAF). It outlines different caching options in MAF including using a local SQLite database and integrating with web services. It also provides examples of implementing read-only and transactional data caching in MAF applications. The document was presented by Andrejus Baranovskis from Red Samurai Consulting who is an Oracle ACE Director and technical expert focused on Oracle Fusion Middleware technologies.

5. Data Caching Complexity
 Relatively easy for read-only data
 Complex for CRUD operations
 Requires to keep track of user changes
 Out of the box approach
 Quick start and easy to implement
 Hard to customize
 Custom approach
 More flexible
 Stable foundation must be in place

6. Oracle Mobile (MAF) Caching Options
 ADF BC to REST DC sync
 Synch Config File
 Lazy Persistence
 Refresh Policy
 DB Storage Folder Path
 Advanced caching with persistence extension

7. SQL Lite Database in Oracle Mobile (MAF)
 Lightweight and portable – self contained simple
file
 Single read-write connection or multiple read-only
connections
 Supports foreign keys
 Dynamically typed
 No role-based or user-based authentication
 MAF provides data encryption routines
