Tips needed

[jake142]

Hi,

I'm amount to build the following application and need some tips from you guys:

- Robust binary archive.
- Archive stores documents (say invoices)
- Need to be able to store billions of documents
- Simple documents that should not be edited or altered. Just be viewed.
- No extra features like versioning etc.
Q: Do you know of any famework, open source product or similare that can do this? Can I simply store metadata in a database and the binary data on disc? In what format should the documents be stored (tiff, pdf, xml + stylesheet etc.)

- FrontEnd to support loads of users.
- High security
- Lightweight and simple
- Should simple list the data in my archive (users should only see their own documents)
Q: Do you know of any famework, open source product or similare that can do this?

Any tips on the above is much appretiated. Framework to work with? Free products to use? What do I need to think about?

I prefer java and PHP. I have looked at things like Alfresco, Joomla, Drupla etc. but feel that I need guidance from the experties (you guys :) )

I prefer to use frameworks that are free to use for commercial use.

Thanks!
