the command to create a database is :
use <databasename>
note : Make sure that database name should not contain special characters because it effects the deployments of mongodb in various environments.
Creation of Collection :
Collection : it s a BSON Document (JSON like format).
simply its a collection of key value pairs.
For naming conventions : _ is used before the collection name.
while creating a collection there are certain parameters that's need to be passed, though they are optional , lets have a quick round of introduction to parameters.
Example : db.createCollection(<name of collection>, {
capped : <boolean>,
autoIndexId : <boolean>,
size: <number>,
max:<number>,
storageEngine:<document>,
validator: <document>,
validationLevel: <string>,
validationAction: <string>});
