LiveCycle Data Services ES

LiveCycle Data Services is a set of Java EE components and APIs used to:

Create data-intensive RIAs with less code, less risk, and accelerated time to market due to an innovative client-server programming model

Integrate RIAs with existing applications, back-end data, and JEE infrastructure

Easily integrate RIAs with LiveCycle document and process services

Enable collaboration, o�ine AIR and real-time data streaming applications to be built in a scalable and reliable manner with robust publish and subscribe messaging

Generate PDF documents from RIAs that include graphical assets

Data Management Bene�ts

1. Automatic Client to Middle-Tier Synchronization

! Change Tracking

! Automatic invocation of remote services

2. Highlander Principle: there is only one instance of a given entity in memory at any given time

3. Con�ict resolution

4. O�ine Synchronization (thanks to Adobe AIR)

5. Lazy loading

6. Paging

7. Cross-client synchronization

Server Integration

! Create and Delete Rooms

! Manage your Users’ Authentication

! Publish and Subscribe to Messages

! Variety of di�erent Languages (some donated by our users, tx!):

Java PHP ColdFusion

Ruby C#Python Groovy


Applications Templates and Provisioning

! Only OWNERs can add new nodes, meaning new collaborative capabilities to a room.

! We want to be able to spawn rooms on the �y (from our servers).

! But we don’t want our users to come in as OWNERs to set up the collaborative capabilities! �at’s too much power!

! What we want is to set it up so that new rooms come with the collaborative capabilities we want, pre-installed.

! �at’s why we have application templates!
