Ellison said another advantage Oracle enjoys on the competition is that its in-memory 12c database doesn't require customers to load all of their data into the database in order to work with it. Instead, it keeps active data in-memory for faster access, storing the rest on flash and disk drives.
The in-memory-equipped 12c also has a hierarchy that automatically manages access to the data, Ellison said.
"This is economical because you don't have to buy DRAM to hold your data. You can have an enormous database and take advantage of flash," Ellison said, adding that it's also scalable and fast.
High availability is another big feature Oracle is touting. In-memory databases from other vendors are vulnerable to downtime, but not Oracle's, Ellison said.
Oracle's in-memory-enabled 12c database stores copies of data on at least two nodes, in a setup that is "very much like disk mirroring, Ellison said.
"There are no other in-memory databases that are fault-tolerant," Ellison said. If a node goes down with the Oracle 12c in-memory database, "you're still in business."
Oracle plans to make its in-memory database technology generally available to customers next month, though it hasn’t yet shared pricing information.
The Oracle PartnerNetwork is also planning to add in-memory database technology to its Oracle Database 12c Ready certification.
