We will give an explanation of how the system is built up, and why we decided to design it the way we did.
The system is used to share pictures between various users. This is done in a feed like way, i.e people can see what others are sharing (assuming they are friends), and can comment on their pictures.
List all system components, subdivided, for example, into categories such as platforms, applications, data records, etc. For each component, state its relevant properties.
Describe the implemented backdoors. Do not add this section to the version of your report that is handed over to the team that reviews your system!
