If you want to know MCS functionality you can check my previous post: Oracle Mobile Cloud Service overview.
Although I already attended Oracle Summer Camps workshop in Lisbon, we are in the middle of a MCS development and this workshop was a perfect fit for mastering my MCS skills and also any question we made was perfectly answer by Mireille Duroussaud (Senior Principal Product Manager).
I was really impressed about Oracle MAX becasue building a Mobile Application connected to Mobile Cloud Service was just a matter of 10 minutes. Although the things you can do with Oracle MAX are limitted, it is likely possible that we will be able to donwload the source code of the generated application to extend it wich is a nice feature.
I think this is a must-attend workshop it you are planning to start a Mobile Cloud Service project anytime soon. You can also check Oracle Mobile Platform Youtube channel where you can find more than 50 videos about MCS.
