How to design a database schema for a multi-user To-Do application in Azure?

Question

I want to create a windows 10 universal to-do app with offline sync capability. So I checked out this tutorial which helped me to get started on the offline functionality. But I was wondering how should I design my Azure database to get data efficiently and moreover I also should have the ability to store images. So here are my questions:

1. Is it good to put all the users data in one table? Ex: (Content Table): ID , FK(UserId), Title, Desc, Created , Edited.
2. Can I use any indexing technique to efficiently query for the user data as CRUD operations will be very common since it has a sync feature.

If the above is not really a good technique could you please tell me what is the right way to go about it. As I'm not so experienced when it comes to DB designing.

Answer 1

For the tables you might want

1. User (User_Id, Name, and so on)
2. Category (Category_Id, Name)
3. Task (Task_Id, Category_FK, User_FK, Name, Date_Due)

This article will give you some background on indexes in Azure.

If you are going to have heavy hits to the database. It would be better to place the database into a caching system. This would take the load off the database.
