I want to create relationship between there tables in sql use oracle tool or another tool?

You are going to need to be more specific about what kind of help you need here. What have you tried already?

about how representing the relation

The diagram already shows you the relationships between the tables.

yes i want to convert this er-diagram to sql code

What have you accomplished so far?

i finished to create the table

That is a good start. The relationships are explained clearly in the description. If you already understand what one-to-many relationships are, you should have no trouble implementing this project.

can we talk together to help me in another way like viber or whatsapp?
