Need Help to build ER Diagram


I am student and while I am pursuing a java-script project. I am done with problem and the solution but fail out with ER(Entity Relationship) Diagram, DFD(Data Flow Diagram Diagram) and Database tables.
I try different ways but rather making and becoming perfect it becomes more complex. Please help??

Doing multiple lines of code on one line

How can we help you?


Identifying entities correctly and then making connections is the basic concept. It to be that complex, it either should have many entities or a considerable lot of relationships. I suggest you try creating ER’s and DFD’s on sample case study. For diagraming, you just need to master the basic rules properly.


Can you help in proper way where I made but confuse a lot, Can you check and suggest me better?
