I have couple of databases named as abc, xyz. If I want to use database "xyz" then type command "use xyz". Command in console show output as "switched to db xyz" but still an user uses commands start with "db" rather than actual name "xyz" why ?
it is because 'db' refers to current database name so all operations executes inside current database rather than any other database.
Please explain me the basics of mongo db? Also telll me when to Use MongoDB Rather than MySQL (or Other RDBMS)
I recently came to know that mongodb doesn't support when we use it for banking transaction software system,is it true? if yes then what other nosql databases that we can use instead of sql database?
