newbie on kdb

A few newbie questions,

  1. is the trial version include kdb+tick?

  2. is HDB in-memory? how does it work with table is larger than memory size/limit

  3. why write math analytics in kdb+q? is it only needed when data is too large for other analytical library? I don’t see how kdb+q can be faster than other vector based math libraries when data size is small.

Thanks a lot

  1. No
  2. No. On disk. Careful with selects, q assumes you know what you’re doing.
  3. Vector operations are very fast. Try it and compare with say R. Other libs may well have more built-in capabilities obviously.
