Each physical item belongs to a collection within the School of SEEC. Likewise, the School of SEEC also provides information as to where to access and download software for student use. Each software item is a part of a collection which exists virtually and is arranged into different categories depending on the course (e.g. Engineering, Computing, etc.) that the software is related to.

Resources

The School of SEEC have many resources that they can loan students during the duration of their degree to assist them in their study or to use during their assignments. Every resource has:

• a resource ID (which is unique)
• a description of the item
• a status (e.g. in use, maintenance, available, borrowed, lost, damaged, etc.)

There are two types of resources students can use; moveable and non-moveable. Moveable resources include items such as cameras, microphones, speakers, etc. Moveable resources have a:

Non-movable resources are resources such as classrooms, laboratories, etc. Each immovable resource has:

• maximum person capacity

Each resource is placed into a category, such as ALL cameras, ALL speakers, etc. Each category has a:

• unique code
• name
• description
• max time allowed to borrow/book (in days and/or hours)

Location

All resources have a location where they are situated that can accessed by staff members and student members alike. These locations have a:

• unique ID
• room
• building
• camp

Loan

Lending and reservation rights are offered to students by staff who are enrolled in courses offered by SEEC. These students and staff are known as members in the system. Members have a:

• unique ID (student or staff number)
• name
• address
• phone number

• offering ID (which is unique)
• course ID (which is unique)
• name
• semester offered
• year offered
• course beginning/end date

Privilege

Staff members can borrow/reserve resources. Staff have no limits on the number of resources that staff can use. Students are granted privileges on what they can borrow/reserve depending on the course they are enrolled in. Courses are assigned privileges to different categories of resources. Each privilege has a:

• name
• description
• a privilege category
• maximum number of resources that a student member can borrow/book at any given time

A member can loan moveable resources (such as cameras, speakers, etc.) if their privileges allow it. Information about the resource when it is loaned is maintained for the duration of it loan.

New Acquisitions

New acquisitions can be made to the School by a student or staff member. An acquisition contains:

• a person requesting acquisition
• an item name

• a description of the required item
• its urgency

The administrator of the system assigns values to the acquitted item such as:

• status (acquired, pending, etc.)
• a fund code
• vendor code
• price
• other notes pertaining to the request

Reservations

Resources can be reserved by members as long as their privileges allow them to borrow/book that resource. The resource will be booked for pickup/use by the student or staff member at the requested date and time after a reservation is made. Reservations have the date and time the item is required and a due date and time. No two reservations should ever conflict as that becomes problematic for one of the members attempting to borrow/book the resource.

3. Late returns by student member penalties
   • Each student member has a default set of points earned at the beginning of their course (12 to start with)
   • For each incurred day that the item is overdue, a penalty of 3 points is given, which is deducted from the total amount that student member has
   • When the points come to 0, member status of that student is disabled, and borrowing/reservation privileges are revoked
4. Cancellation of Reservations
   • A reserved item is cancelled if it is not collected by the member on the day of the required due date
   • Non-cancellation of a reservation by a member means 1 point is deducted from the members total

5. Borrowing/Reservation Periods
   • The duration of the borrowing/reservation periods, being either number of days or hours, is determined by the category to which the item belongs
