I am designing a Flash-based language course, and I am not sure which architecture I have to choose. The content won't be uploaded to the Internet, it will be used only locally.

Possible architectures:

1) A single SWF with all the data stored internally - it seems a rather clumsy and inefficient way (or it's not?).

2) To make a Flash-based interface, and to keep the data saved in a MySQL database. It presumably allows to organize the content better, avoiding self-repetitions. The problem is that the language teacher (who is not an IT specialist) will have to install additional software to handle MySQL.

3) To make a number of separate SWF files, and to make a simple HTML-file with the index.

(and some other solutions I didn't think of)

Which is the right architecture, most usable for the teacher and most elegant from the IT point of view?
