This was one of the interview question that I faced.

A log file contains the text in the following format
logTime appName loglevel logText
logTime appName loglevel logText
logTime appName loglevel logText
logTime appName loglevel logText
.
.
.
.
n

which is the best suited Data structure for this. Such that we can search logs. For instance log search with condition as logTime or condition as LogTime and appName?

Two Master tables for App Name and Log level. Another table having log time, log text and FKs from master tables. Total 3 tables required.

Then you can query DB using various JOINs.

Sorry, you asked what was the best. A database would be best.
