Since the emphasis is on the database connectivity, neither a GUI nor a web application is required. In fact, a GUI would require x2go, which I don't have at home and you probably don't either. A web interface would need to be on osiris, I could figure out some way to try it out, I guess. There are also numerous security concerns. The applications should be easy for someone like a store employee or on-line customer to use. The most common operations, such as adding a customer or renting a tool, should be implemented.
