protected virtual function bit do_open_db()
Open the backend connection to the database.
Text-Backend implementation of <uvm_tr_database::open_db>.
The text-backend will open a text file to dump all records in to. The name of this text file is controlled via set_file_name.
This will also lock the file_name, so that it cannot be modified while the connection is open.

protected virtual function bit do_close_db()
Close the backend connection to the database.
Text-Backend implementation of <uvm_tr_database::close_db>.
The text-backend will close the text file used to dump all records in to, if it is currently opened.
This unlocks the file_name, allowing it to be modified again.

function void set_file_name( string filename )
Sets the file name which will be used for output.
The set_file_name method can only be called prior to open_db.
By default, the database will use a file named “tr_db.log”.
