    Entity Relationships

    Basically i have two database tables

    Patient
    Patient Number | Patient Last Name | Patient First Name | Patient Address


    Patient Charges
    Item Description | Item Code | Patient Number | Amount

    How do I make a diagram showing the relationship between the entities Patient and Patient Charges?

    Try Powerpoint. I find it very useful more making simple diagrams.
    If it's not practically useful, then it's practically useless.

    Dia may be an option for you - the price is right, it works on Linux & Windows, etc. It does general purpose diagramming, flow-charting, network layout, and ERD diagrams among others.
