Enhancing a Database with File Uploads
You can add more functionality to your database after it has been created, like allowing students to upload to the individual entries. From within the database click the "Fields" tab and then the "Create a new field" dropdown. Select "File" then name and describe what you want them to be able to upload and click "Add". If you go to the "Templates" tab you will see that a data type with the name you gave it is at the bottom.
When students go to the "Add" tab they will see a file upload window in addition to the other data fields.
