database - Is local bitmap index better or normal index, if table partition is not used in query -
i have partitioned table column of enumerated values (i.e. non unique), , want make index on column enhance performance of query doesn't include partition in clause (i.e. runs on entire table) .... better make local bitmap index or normal index ? ... using oracle 12g
a bitmap index better non-unique values age,sex,location etc. depends on volume of data,size of db , how frequent updates etc.
below read.
