Computer Science - Database Systems - E-R Diagram & Relational Schemas

Thanks for the help.

An event organizer needs setup a database to keep track of a collection of workshops. The following information needs to be recorded. Each workshop has a unique name. A participant (identified by the email address, with name as attribute) needs to register for at least one workshop. Meetings rooms are identified by a floor and room number with capacity as attribute. Every workshop needs one and only one meeting room. Draw an E-R diagram for this database. Show the set of relational schemas according to your E-R diagram
