URGENT: Microsoft Access Database and Query Help

Deadline is less than 1 day - I have to create tables and quires and relationships for an assignment using access. I have tried but i am a bit stuck and need some help. I also would like the explanation behind the solution so i can learn from it as well. This is what i have to do: 1: Convert a entity-relationship model provided into a relational database design. I have done this but need advice if done correctly. 2:Create the tables (6) in a database according to your relations from the previous step. I have done this but not sure that i have "Pay careful attention to physical design requirements, including data types and sizes, integrity constraints, indexes, etc; your choices should be aimed at ensuring data integrity. or paying attention to referential integrity and cascade options." 3:Formulate SQL quires. I have attempted most of them and research on the net but having trouble with a few of them. This inclueds: *"DateDiff" * I think a "sum" but with date specific crieteria. *write two separate queries and use a UNION to show both results sets in the output, not showing duplicate rows. 4: Need to create a form based on the tables. I have done this but would like someone to check it and give advice. It is not too hard, but i do need help cause i study distance education it makes it harder as i have no international with others. If you can help by writing a brief description or reason for each question that would help me. I can email you the database if yo are interested. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
