Offline data storage (HTML5)

Post by WABez »

I've been investigating and looking at HTML5 offline storage and think this is another wave to follow since HTML5 is reshaping the web experience for Internet websites and line-of-business (LOB) applications.

Two key HTML5 features will dramatically change LOB applications: offline application support and local persisted storage. With the offline capabilities and local persisted storage features, we can deliver the same rich user experiences online and offline that were previously available only in proprietary desktop application development frameworks.

When online, all CRUD operations use the servlets for the create, modify, and delete operations. The local cache is also updated when the online database changes.

When offline, all CRUD operations use the local data provider to persist the changes. Upon reconnecting with the server:

  • Any records that were created locally are persisted to the server.
  • Any records that were modified locally are updated on the server.
  • Any records that were deleted locally are deleted on the server.
