Catch me if you can?
It's not just Teradata's market cap that would deter buyers - IBM is buying Netezza, HP has Neoview (no, seriously), Oracle has Exadata, Microsoft swallowed Datallegro some time ago and recently EMC bought Greenplum to join the parallel DBMS party.
Why did NCR spin off Teradata is surely the real question!?!?!?
Paris, as she's 'reassuringly expensive'.
