database - Looking for data in a table through colums with categories/state values -

-

say have fruits that having high number of reads inserts though not update nor delete.

we have 2 columns stores values have small number of options. lets categories[banana, apple, orange or pear] , status[finished, ongoing, spoiled, destroyed or ok].
finally, have column last name of owner.


notes:
going searchs category , other status.
in cases, lastname used search.
perform exact match on categories/status start in last name.

ex of common queries:

select * fruit_table category='banana' , last_name 'cool%' select * fruit_table status='spoiled'  , last_name 'co%' select * fruit_table category='banana' , last_name 'smith%'




how can prepare have low response time?
will index help(taking account values in column not disperse @ all)?
might bitmap index here?
what partitioning?

finally, apologies title, did not know how formulate properly.

  • bitmap indexes immensely items have limited number of available choices.
  • a standard b-tree index (or non-clustered in sql server) work last_name column.
    2 first, easy , see how things work.

it bad practice prematurely optimize. however, adding indices quick way increase speed without effort. more information on indices in oracle, read this question.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2...
