Hello readers!

Many time we get stuck with the query How to get the database information in Mongodb? Here below is the simple answer for this query-

We can easily get the database information using below predefined methods:

a) show dbs - Populate a list of all databases on the server.

Syntax: db.showdbs

b) show collections - Print a list of all collections for current database.

Syntax: db.showCollections
Result: collection1
            collection2
            system.indexes

c) db.stats() - Returns statistics that reflect the use state of a single database.

Syntax: db.stats(scale)
Example: { dbStats: 1, scale: 1 }
         { dbStats: 1, scale: 1024 }

-scale parameter is optional. We can scale at which to deliver results. Unless specified, this command returns all data in bytes.

d) db.runCommand( command ) - Provides a helper to run specified database commands. This is the preferred method to issue database commands, as it provides a consistent interface between the shell and drivers. -command - A database command, specified either in document form or as a string. If specified as a string, db.runCommand() transforms the string into a document.
