Neo, wake up! SOA has you! :) A complete accademic overview about the Web Oriented Architecture. A comparison between WOA and SOA is well described. What is ReST and why it is so important for the WOA. A proxy ReST-to-SOAP, based on Oracle Service Bus, is explained. Which products WOA lovers are searching for? This presentation has some "sponsored slides" from Oracle.

25. What is a datagrid? Caching Applications request data from the Data Grid rather than backend data sources Analytics Applications ask the Data Grid questions from simple queries to advanced scenario modeling Transactions Data Grid acts as a transactional System of Record, hosting data and business logic Events Automated processing based on event

36. Scaling a SOA with the Datagrid

40. Restifying and caching a SOA

41. RSD: parse the URL http://siebel.com/rsd/catalog/product/id/5461 ?n1=v1&n2=v2… get / put / post / delete

42. RSD: check if cached Check the cache only if GET method has been used Assign a XML payload to a variable Send the payload to Coherence through the OSB Transport if Coherence is not UP a WS call will be done If the item is not in the cache a WS call will be done) Skipcache variable will be tested to decide if it is the case to return the cached value or invoke the WS

45. RSD: the configuration file GET /rsd/catalog/categories/id/3473 The following URI parts select the needed WS parts: This is the SOAP operation to invoke This is the SOAP payload to load This is the SOAP response to return But, what about the URL parameters?

46. RSD: the configuration file GET /rsd/catalog/categories/id/3473

RSD: check if cached Check the cache only if GET method has been used Assign a XML payload to a variable Send the payload to Coherence through the OSB Transport if Coherence is not UP a WS call will be done If the item is not in the cache a WS call will be done) Skipcache variable will be tested to decide if it is the case to return the cached value or invoke the WS
