prompt: Your task is to convert the following English description into an ASCII tree format.
  
  db is a origin directory that houses 3 subdirectories: backends, migrations and models.
  At the top level, 'backends' stores 6 many nested folders.
  At level 2, in directory path 'backends → base', Inside 'base', you'll find it has nothing inside.
  In nested path 'backends → dummy', The 'dummy' folder has been left empty.
  In nested path 'backends → mysql', 'mysql' lacks any subdirectories.
  In nested path 'backends > oracle', The 'oracle' section lacks any subdirectories.
  At level 2, in directory path 'backends > postgresql', The 'postgresql' container is empty.
  Within directory hierarchy 'backends > sqlite3', Inside 'sqlite3', you'll find it stands empty.
  Back to the top level.
  At the main level, 'migrations' keeps 1 subfolders: operations.
  Within directory hierarchy 'migrations → operations', 'operations' contains nothing at present.
  At the main level, 'models' possesses 3 subfolders: fields, functions, sql.
  Within directory hierarchy 'models > fields', Inside 'fields', you'll find it is barren.
  At level 2, in directory path 'models > functions', The 'functions' storage space is devoid of content.
  Within directory hierarchy 'models → sql', The 'sql' storage space is empty.
