input: Write a function to simulate a Flask application that submits form data (Name, Email, Phone) and stores it in a database. Return the status of the submission as a string, either "Success" or "Failure". If the form data is submitted and stored successfully in the database, the function should return "Success". If the submission fails for any reason, it should return "Failure".
  assert submit_form("Alice", "alice@example.com", "1234567890")=="Success"
  assert submit_form("Bob", "bob@example.com", "0987654321")=="Success"
  assert submit_form("Charlie", "charlie@example.com", "abcdefghij")=="Failure"
  assert submit_form("", "email@example.com", "1234567890")=="Failure"
  assert submit_form("", "", "1234567890")=="Failure"
output: def submit_form(name, email, phone):
      if not name or not email or not phone.isdigit():
          return "Failure"
      # Simulate storing data in a database
      # Assume the database operation is successful
      return "Success"
