how do you draw a network diagram for a hospital database?

This is a strange question to ask. I will attempt to answer it as is and propose additional other questions.

A network diagram is a picture of hardware components that communicate with each other. For example a client talking to a server will have a picture of the client, a picture of the server, and a line between them. Clients are usually represented as little computer nodes or cell phones or laptops depending on the device. Servers can just be drawn as boxes with names on them. Databases should be drawn as cylinders with stripes wrapping around them on the outside.

At a location such as a hospital, there may be more than one database. These databases might communicate between each other. They may be hosted on the same system or multiple systems. Your network diagram should consider these things and graphically show them. To show multiple programs running on the same system, just draw a bigger box around the programs and label it with the machine name.

You should include all networking components: databases, firewalls (drawn as a brick wall), clients, websites, routers, modems, the Internet (drawn as a cloud).

A good program to make these sort of diagrams is Microsoft Visio. However, there are other free alternatives on the web. I believe Visio even has a template for network diagrams.

Now this may not have been your question... but you may want to know how to draw the entity relationships in a database. This is how each of the database entities (objects) relates to all other entities. For example, an entity might be a customer and another entity might be a medical supply. The customer receives the medical supplies. But you'll have to add another entity (the doctor) which provides the medical supply to the customer. After that, you should have a supplier who provides the medical supplies to the hospital. You can add a hospital that has a list of doctors. These entities have relationships which help to map what data your database will store and what foreign keys you will need to create in order to force the integrity of those relationships.
