I had a lot of trip plans on weekends, so I keep my favorite stores, places, and some locates in my personal cloud database, and I also build the App to maintain this database. This App has functions : 1. User login/logout/forget password 2. add, modify, and delete new trip data function. 3. User permission control. 4. Users can comment on every data. 5. Can save the data to favoriting list.
