    an interesting explanation of ERD, step by step in a simple, slow way that makes it easy to understand, thank you Mr. Dr. May Allah increase your knowledge

    This video isn't really about an ER diagram. It is talking about a "relational model". An entity/relationship should not be talking about primary key or a combination key and such relational database terms. E.g. "An employee works for a department" - there are two entities "Employee" and "Department" and the relationship is "works". So you should pick the 'entity' icon on the left (rectangle), and the relationship icon on the left (diamond shaped). Then you draw the cardinalities (one-one, one-many.. etc). Between the rectangles (entities) and the relatioship (diamond), you draw the cardinality lines (one, many, etc).

    OK, and how do I create a composite PK which consists of 3 fields? Anything I try, it puts it in a different row that is divided by a horizontal line. I'm unable to put 3 PK's between two horizontal lines. Like the two PK's in the EmployeeSkill here, only I want a 3rd one in there too. How to do that??

    This is not an ER diagram. It is a relational schema. ER diagrams are part of the conceptual database design and aren't related to a specific database type.
