Assignment: Processing complex xml sources from the Chicago Mercantile Exchange (CME) to
load derivatives instruments into our production database, parsing heavy xml files (several
hundred mbs) and enriching their contents before inserting. Technologies and functionalities
used: Oracle built-in xml processing packages and Visual Studio 2012 xsd schemas generator.
As we didn’t have access to the xsd schema we had to generate it by ourselves based on the xml
files. Registering the xsd schema greatly increased the parsing and insertion speed (from almost
2 hours to 10 minutes).
