Create an Entity Relationship Diagram (ERD) of the normalized version of this table using Visio's crows-foot notation. The ERD should show the PK and FK columns, plus all of the appropriate column attributes (column name, data type/size, null/not null) plus the relationships (with minimum and maximum cardinality) between tables. Requirements: Show the results of the normalization as individual tables Show the FK and PK columns using Visio's notation You must solve the multi-column issue with grades (Hint: This will require a new column) Show the 3-part column definition as noted Show min/max cardinality Tables are attached
