To draw an ER (Entity-Relationship) diagram for a tourism system, first identify the key entities such as Tourist, Tour, Destination, Booking, and Guide. Then, define the relationships between these entities, such as a Tourist "books" a Tour, a Tour "includes" multiple Destinations, and a Guide "leads" a Tour. Use rectangles to represent entities, diamonds for relationships, and lines to connect them, indicating cardinalities (e.g., one-to-many, many-to-many). Finally, label attributes for each entity, such as Tourist ID, Tour Name, and Booking Date.
