2nd meeting: tasks

Questions Creation And Storage

Creation can be done through a JSON file: questions.json, which is uploaded along the slides. It can also be created with the help of an online editor.

The questions can be stored either in a JSON file or in a collection (preferred)

Markup of the question is defined in a view (ejs file) and css.

Data Structure & Storage

First Suggestion

Slides are uploaded as above. (As an archive if the upload of a directory is not possible.) the questions.json file is parsed and integrated in a collection, the rest of the uploaded data remains as is, in the folder.

The remaining data will be stored in a multiples collections (MangoDB). See chart below:

Second Suggestion

Slides are uploaded the same as above except for the questions.json file which is not parsed into a collection but left as is and loaded into memory if the slides are needed.

This case only uses two collections, the users and the slides:

This can also be found on the suggestion page.

Pros And Cons

First Suggestion	Second Suggestion
Pros Cons Modular More complex Scale more easily Larger number of collections Separation of information Redundancy and increased overhead Organised, easy to maintain	Pros Cons Simple Rigidity Less collections Immobility No needless repetition More difficult to share information Faster to implement at first Must load questions from JSON into memory
