Hi,
I have gone through the requirements and i can build required data model and also i can help you with SQL script.I can start immediately so once i got confirmation i will work on the relational model.
I have 11+ years of development experience and i can solve your problems.
Thanks
hey! I can do that for you, I have good experience in SQL. Are you allowed to build the diagram using any tool like workbench or phpMyAdmin? Let me know then. Have a nice evening :)
