▪ List the functional dependencies.
▪ List your tables.
▪ Create the database including everything (tables, relationships, keys etc.). You may use any database management system.
▪ Create the user interface of at least 5 modules using any programming language. Choose the interfaces according to the questions below.
▪ Create 1 OUTER RIGHT JOIN, 1 OUTER LEFT JOIN, 1 FULL OUTER JOIN queries on user interface.
▪ Create and use at least 5 different triggers making completely different tasks.
Show how they are working in your interfaces.
▪ Create and use at least 5 different views that are completely different from each other. Show how they are working in your interface.
Additional:
▪ Give and create at least 3 atomic transactions.
▪ For at least 3 tasks solve concurrency of transactions using any techniques in the book.
▪ Add additional details about the database if there is any. ▪ Use inheritance for the tables.
