! Web Services Description Language 1.1 (WSDL 1.1) document

! �e Flex web service API generally supports Simple Object Access Protocol (SOAP) 1.1, XML Schema 1.0, and WSDL 1.1 RPC-encoded, RPC-literal, and document-literal (bare and wrapped style parameters).

! Flex supports web service requests and results that are forma�ed as SOAP messages

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

Blaze DS

BlazeDS is a set of Java EE components and APIs, and a subset of LiveCycle Data Services:

- Free and open source.

- High performance data transfer for more responsive applications using AMF

- Real-time server push over standard HTTP

- Full pub/sub messaging that extends existing messaging infrastructure

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

Model driven development


Code Driven Development

Code •UI controls / formatters / styles• Calculated �elds• Validation Rules• Variants (conditional properties)• Localization• Security• Data Retrieval Logic (paging, lazy loading)• Data Synchronization Logic

Model •Basic Data Description

Model Server-side code Client-side code


Model Driven Development

Code• Ad-hoc customization• View composition• External business/validation logic

Model • Rich data model (data and behaviors)• Calculated �elds• Validation Rules• Variants (conditional properties)• Localization• Security• UI hints/defaults: controls, formatters, styles

Model includes enough information to derive data retrieval, persistence, and synchronization logic

Model Server-side code Client-side code


Model Driven Development Bene�ts

Productivity: Less code to write

! No persistence code or data sync code

! Value objects and service stubs are automatically generated

Maintainability: Less code to maintain

! Changes to the model are automatically propagated

Consistency

! Between client and server (for example, constraints and validation rules are de�ned in the model, not duplicated using di�erent languages in the client and the server)

! Across views (for example, UI controls, styles, and validation rules are de�ned in the model, not duplicated across di�erent views)

Approachability

! No code to write to implement complex capabilities such as persistence, synchronization, paging, lazy loading, o�ine, etc.

Innovation:

! O�ine and client synchronization capabilities

! Model is language independent and can be leveraged by di�erent client technologies and tools (Flex, PDF, etc)
