Continuous inventory update (programatically)

Hi everyone,

I'm just getting started with Opencart so please bear with me.

I'm looking to write a module that can add/update products from MongoDB and since this would be done daily for over 3000 products, thats why it has to be an automated process and needs to be done programatically, so using an import/export extension won't work.

I'm wondering whats the best way to go about it:

- Events (script notifications)
- VQMOD
- OCMOD

Any pointers would be really appreciated. Thanks!

Because import and updates will affect only the database, only model files are relevant.

And using Events, VQMod or OCMod is up to you what you prefer.

VQMod: if not used by other modules, why installing an additional Module?
OCMod: is already integrated, the syntax is not very differnent - best choice.
Events: if the hooks are already existing, can be used also.
