Data Grid Uses 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

28. Restful SOA Datagrid: OSB pipeline

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

30. 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

31. RSD: return cached item If the result has been taken from the cache return it

32. RSD: set up WS call This is the main configuration file. From this file, RSD is able to match the provided URL with all the parts of a standard WS call: Business Service , the Soap Action , the header and body SOAP with the relative parameters

33. 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?

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

35. RSD: the response Get the response Transform from XML to JSON Put it in the cache
