Question

I am trying to create an app that will give users the option to create a new project or select an existing project. These projects will contain a name (title) and a group of images they are allowed to take. Basically an album. The only way I can think of doing this is by writing to a file the name of the project and a bunch of id’s for every picture they had selected for that project. Store this in an array and reload it every time they start the app. Is this a good way to go about doing this or is there a more eloquent way of doing this?

Answer 1

you could use a sqlite database to store the projects in a table and in another table store the list of images and in a third table a list which image belongs to which project(s).

You could use the following tables:

Projects table

---

ID – AutoInt

Title – varchar(255)

---

Images table

---

ID – AutoInt

ImageID – Int

---

Project Image relation table

---

ID – AutoInt

ProjectID – Int

ImageID – Int

---
