input: def Model_CRUD(method, name=None):
      """
      This function provides the standard CRUD (Create, Read, Update, Delete) operations for a simple ORM-like model that interacts with an in-memory SQLite database. The model stores a single attribute 'name' of type string.
  
      The function should be called with two parameters:
      - method: a string representing the operation to perform: 'create', 'read', 'update', or 'delete'.
      - name: a string representing the name to be used in the 'create', 'update', or 'delete' operations. For the 'read' operation, this parameter should be None.
  
      Example Usage:
      >>> Model_CRUD('create', 'John')
      >>> Model_CRUD('read')
      [('John',)]
      >>> Model_CRUD('update', 'Jane')
      >>> Model_CRUD('read')
      [('Jane',)]
      >>> Model_CRUD('delete', 'Jane')
      >>> Model_CRUD('read')
      []
