Attached please find a MS Access 2013 database file, including a DB with 3 "empty" Tables: T1, T2, T3. The table relationships have been defined in the MS Access DB, although the tables have no record.
P.S. The T1/T2/T3 relationships are very unusual, but it is correct!
(1) Find your own ER-Diagram Tool to create a new ER-Diagram for the MS Access DB, but without the redundant alias Tables (e.g. MS Access added redundant T1_1, T2_1, T3_1).
(2) Use the ER-Diagram Tool to generate a new MySQL DB (with your ERD from Step 1), and please add some sample data to 3 Tables.
(3) Implement a web demo using PHP + MySQL DB, let user CRUD T1 or T2 or T3 table records on web.
