Fetching and forgetting data access is not optimal for mobile applications and Oracle Mobile Application Framework in particular. Data transfer is expensive in terms of performance and network bandwidth for mobile applications. We should optimize this and implement data caching for successful Oracle Mobile Application Framework applications. Learn how to use a local Oracle Mobile Application Framework SQLite database to cache data and minimize web service calls. This practical session explains a strategy for how and when to cache and refresh data and includes live demos for Oracle Mobile Application Framework data caching strategies.

Relatively easy for read-only data
Complex for CRUD operations
Requires to keep track of user changes
