Student needs help with database planning

Question

Preliminary Plan
I work at the headquarters of a small company of 8 offices and 26 employees. I am the central database system. Right now, information is only accessible through me, by me, from me, and to me via fax, phone, mail, or email. I have several spreadsheets with different information resulting from personal information, cell phone information, laptop information, government vehicle information, contract information, and training information.
I want to develop a database that will automatically keep track of this information as entered by the user. Whenever there is a change or update, the system will be able to automatically accept this information into the system. Information will come from each workstation in the office that only the managers and I can see. The managers will however only have access to their individual employee information, but I will have access to ALL the employee information. All information created, provided, and maintained between me and the managers will be conducted through RDBMS. Triggers will be used so that information can be updated or inserted through SQL. LAN-to-LAN connections are already in place so that information on the network can be accessible. Preliminary plan is as follows:

Answer 1

My major is information system. I want to be able to
access information from all 8 stations where the user
inputs the information, but only have access to their
employees and I will have access to all 26 employees.
I being the central database system.Still quite vague, if you ask me. If it's just an entry formular with user authentification, your time schedule may work. Installing XE and developing with APEX could just be the right tool for this job, but without any further information (data structures, authentification concept, user interface) it will remain pure speculation from my side. Why not ask your teacher if he/she thinks your plan is reasonable?
