Question about OC's database

Hello~ English is not my native language so there might be mistakes.

I'm planning to update my site to OpenCart, but I'm not sure if it has feature I would need.

I need my site to have one database and four different shops. For example, there is database and then I have shops selling shoes, handbags, jeans and the wholesale store. Database should have all the items and shops would only have some of them. BUT the items would be mixed up like wholesale section would have all items and shoe shop might have few handbags etc.

Most important part is that if someone buys the last handbag, the item will dissappear from all the stores.

All stores would be at different addresses and have different layout.

I have checked Opencart Marketplace tool but I'm not sure if it has all the parts I need.

Yes, it should be possible to do all of that with OpenCart's multi-store feature. See this: http://docs.opencart.com/en-gb/administ ... lti-store/
