comment The implied volatility surface and the option Greeks - to what extent is the information contained in their daily movements the same?
Not really. It all depends what sensitivities you try to derive. If you look at sensitivities of certain variables to changes in the implied volatility then those hardly correlate with, for example, theta, the sensitivity of the option price to the passage of time.

comment Databases for storing and querying high frequency tick-level data?
@Arman, check out Teafiles, also consider writing your own binary data store, or you could consider document DBs, but other than that there are not a whole lot of open-source columnar DBs out there.

comment Databases for storing and querying high frequency tick-level data?
out-of-the-box? This concept does not exist in finance, unless of course you want to "trade" bitcoins. Whatever time series store you decide to go with you will not get around doing a lot of performance analytics, tweaking, and customization. Just for your reference, KDB generally sends a host of "consultants" who stay for several days just to setup the initial database structure.
