SOA For Database Professionals

This seminar explains in a high level overview what the key SOA concepts are. It introduces WebServices and the key XML mechanisms, such as XSD, SOAP, WSDL and a touch of XPath and XSLT. It describes the respective roles of BPEL PM and the Enterprise Service Bus. It will then demonstrate how from PL/SQL programs – and even from SQL queries – SOA Services offered in BPEL or ESB can (and sometime meaningfully should) be leveraged, for example to perform operations across databases or even heterogeneous data stores.

Oracle SQL Inside Out

From calculating the group standings for the Champions League and finding the shortest route from A to B, creating a fuzzy search that returns records by relevance and score with regard to search criteria, to creating a personalized television guide, producing charts, emulating a supermarket cash register, creating a test data generator, implementing a highway speed controller and devising a mobile telephone billing application, we take on clear situations and find ways to make SQL do the work.
