Now that you finished developing the database backend, it is time to design and develop a front end for the application. You will create forms and a menu to allow users to access your database. Listed below are the requirements for the forms and menus.

Please be aware that the appendix is an integral part of the lab requirements.

Please do not put your name or any other identifying information on your forms.

NOTE: Prior to starting Lab 2, ensure your Lab 1 tables are correct. You will also need to drop all procedures, functions, packages, and database triggers associated with your Lab 1 tables.

P => Form Property, T => Form Trigger

1)Source Code / Executables / Submission 5 marks
Each form will be in its own separate file
Each data block will be based a single table, do NOT use table joins or views when creating a data block!
Note: master-detail relationships are not considered table joins
All multi-line forms MUST have all the data from one record on a single line
Create all your forms and menu in the OracleDocs\Marking directory
When you are ready to start fully testing your lab: leave the executable files in OracleDocs\Marking, move all your source code files to the OracleDocs\Source directory, open an Internet Explorer browser, and type the following URL:

When you are done your testing, submit your lab via Moodle as follows:
Copy your executable files to “Lab 2 Marking Files Submission”
Copy your source code files to “Lab 2 Source Files Submission”
Ensure you only submit your final Lab 2 files (i.e. No classroom, test files or versions of Lab 2) and do not compress any files
Email your instructor a discussion about the lab including, but not necessarily limited to, the following:
What you liked and/or disliked about the lab
How long the lab took to complete (divided into “in class” and “out of class” time)
Any significant problems you encountered
Whether there was enough material provided in the lectures to complete the lab
What, if any, changes, or improvements could be made to the lab
Anything additional as specified by your instructor
