ConceptsService-Oriented Architecture

SOAPEX: The Oracle SOA Suite and APEX

Three 'Streams' APEX instead of ADF/JAVA/SOMETHINGELSE in a SOA Architecture APEX is good for UI development Used in ‘Silo’ Applications (Domain Specific) Fast, reliable, easy to learn, … Agile The “Data-less” APEX application All CRUD actions trough services (Almost) no data within the APEX-app itself, just service calls. APEX Custom Application Connecting to Other App’s trough SOA Suite Combination of the above 27 © 2011 Capgemini. All rights reserved.

Example: APEX and the Oracle E-Business Suite

APEX & Oracle EBSWhy? Incorporating standard functionality Oracle E-Business Suite in Custom APEX application.
