Database is the high level Tango object which contains the link to the static database.
Database provides methods for all database commands : get_device_property(),
put_device_property(), info(), etc..
To create a Database, use the default constructor. Example::
db = Database()
The constructor uses the TANGO_HOST env. variable to determine which
instance of the Database to connect to.
If TANGO_HOST env is not set, or you want to connect to a specific database, you can provide host and port to constructor:
db = Database(host: str, port: int)
or:
db = Database(host: str, port: str)
Alternatively, it is possible to start Database using file instead of a real database:
db = Database(filename: str))doc")
