Agenda

Service Orientation Defined Data Services Rich Internet Application Scenarios XAware Technology Features XAware Metadata Creating an XML View Deployment Environments Demonstrations

Data Service, mashup from file and database Inbound XML Processing (shredding) into different database

tables

3

Service Orientation Defined

Service – a set of capabilities grouped around a functionalcontext (example: Customer, Order, Shipment). Service Contract specifies interaction Loosely coupled Composable

Goals Interoperability through standardized interfaces Business agility through orchestration of services Reduced vendor dependence Alignment of IT with business

Service Oriented Architecture Architectural model facilitating service orientation The “Service” is the primary means by which computing

capabilities are expressed

4

Data Services

Services that provide data access in a service orientedmanner

Also known as Entity Services, Business Object Services Establishes a data abstraction layer

Rationalize data into meaningful entities Decouple from physical sources Combine multiple sources into one logical entity

5

RIA Scenarios

Populate visual structures with data (forms, tables, charts, etc) Invoke capabilities on services Services for RIA can be managed just like other services Granularity is typically much more detailed Reusability may be less due to granularity (though designers

should seek reusability as a design goal).

XAware Project Overview

XAware provides real-time data integrationenvironment for composite data services Eclipse Plugin IDE Runtime Engine: J2EE, Servlet, Batch Mode, Java API

Project hosted on www.xaware.org Forums, Wiki, Hives, Blogs Self-training material Forge on www.SourceForge.net

Binary Distributions (All-In-One and Eclipse Plugin) Source Code Bug Tracker

Problem: Over 60% of development timespent on Data Access

Transactions Error Handling Extension Points Security

Inbound XML Decomposition Synchronization Conditional Logic

Aggregation Data Chaining

Solution: XML abstraction layer reduces complexity andspeeds development

Solution: Composite DataServices Layer

XAware Components

XAware Designer – Eclipse plug-in Visual drag-and-drop, wizard-based IDE that speeds the

development of XAware-powered applications XAware Engine

High-performance, scalable, dynamic data integration anddata services execution engine

J2EE, Servlet, Batch, or Embedded

Adapters Provide connectivity to requested data sources and systems;

SQL, FTP, Email, SNMP, Text, RMI, Cobol Copybook, File,XSL, LDAP, Java, EJB, JMS, MQ, others…

Connectors Provides synchronous and asynchronous connectivity from

client applications to XAware-delivered services via SOAP,JMS, EJB, HTTP, HTTPS, and Java API
