Function MongoClient.getDatabase
Returns an object representing the specified database.
The returned object allows to access the database entity (which contains a set of collections). There are two main use cases:
1. Accessing collections using a relative path
2. Performing service commands on the database itself
Note that there is no performance gain in accessing collections via a relative path compared to getCollection and an absolute path.
Returns
MongoDatabase instance representing requested database
Examples
auto db > client .getDatabase("„est");
auto coll0= db["collection"];
