Re: Run your enterprise on a cell phone?
SAP made a big marketing splash with the 'entirely in memory' database message, but then walked it back when asked specific questions. How do you ensure that data isn't lost forever when a server crashes? Well, we write it to persistent state storage at a very short interval... so, then, you're still only moving as fast as the storage system..... Isn't it going to be really expensive to store all of the legacy data, which is most of the DB, in memory? Well, you can archive to disk.... again, maybe not a problem, but not really in memory. What you get when you dig into it is that you will be storing read only in memory, which is not new.
On the 'run your enterprise from your phone' message. Why would a CFO want to dig through the transactional GL data on their phone? They just need the dashboard view.
