A key process in database development is obviously database modelling and the main diagrams used are ERD. A number of notations exist, some particular to evangelised by particular DBMS. Here I am documenting a short course/notes about ERD modelling using the Barker’s notation, which is greatly adopted by Oracle.
As usual here is the link, do feel free to comment!
In God we trust, everyone else must have a X.509 certificate.
Thanks for this, the Barker notation is where I started out with ER concepts. Nice precis. Happy New Year!
