Unit 6.7 and 6.8 - Coggle Diagram

- - - - Issue each student with an ID card.
      - This would contain a magnetic stripe (shown
        in black) on the rear of the card.
      - This data would now be stored
        on a database.
      - The student would have to sign the card and
        also write his unique student ID on the back of the card as well
      - On leaving the school (either at lunchtime or at the end of the
        day), the ID card would again be swiped
      - what it contains
        
        The magnetic
        
        stripe would contain the name of the school, the name of the student, the
        
        student's data of birth and their unique ID (registration) number.
      - This would now record the leaving time and data on the database
      - Each morning the student would arrive at the school and swipe their ID card
        through a magnetic card reader.
      - This would give a very comprehensive record of when
        the student attended the school and the number of hours they attended.
      - The data read would identify the student and the
        time and date they entered the school's premises.
      - It would
        also be a more secure method in the event of, for example, a fire .
      - advantage
        
        The school
        
        woulcl now be able to account for every student currently showing as being
        
        present on the school premises.
      - advantage
        
        Using the paper-based system, a student could
        
        register then just go home - with this ID card system, the student's attendance
        
        would be larown at all times
      - MORE INFO
        
        There are further subtleties that could be used such as (1)use of a PIN to
        
        stop another student swiping in with the wrong card (2) use of GPS tracking
        
        so the exact whereabouts of a student would be known; this
        
        would require the addition of a chip in the ID card so that the tracking system
        
        could identify, them ).
        
        At the end of a term (or school year), the database could be interrogated and it
        
        would give an accllrate attendance record for the student.
    - - could make use of biometrics
      - WHAT IT INVOLVES
        
        Each student would have their
        
        fingerprints taken. Their personal details (as in method 1) plus fingerprints would
        
        be stored on a database. When a student enterecl the school premises, they would
        
        be asked to put their hand on a scanner which would read their fingerprints. Since
        
        each student would have unique fingerprints, this system would be very secllre.
        
        As with method I, the date and time of entering or leaving the school would be
        
        accurately recorded on the database.
      - ADVANTAGES
        
        POINT 1
        
        Fingerprints are unique, so it would be impossible for a student to sign in
        
        pretending to be someone else (with magnetic cards, a student could give his
        
        card to a friend and ask them to sign in for him) - this gives more accurate
        
        data and improved security
        
        ID cards could easily be lost - fingerprints are 'part of you' so can't be lost
        
        ID cards could be affected by magnetic fields (..g. by being placed close to a
        mobile phone) which would stop them working.
        
        It is much easier to 'clone' (i.e. make copies of) ID cards than it would be to
        copy fingerprints (not impossible but very difficult).
      - DISADVANTAGES
        
        It would take a long time to collect the initial fingerprints for every student in
        the school.
        
        The equipment needed to take and read fingerprints is more expensive than
        magnetic stripe reading equipment.
        
        If a student cuts a finger, the fingerprint may not be identified by the system
        (which would prevent entry to the school).
        
        There are 'invasion of privacy' issues and some parents may object to having
        the fingerprints of their children stored on a database .
  - - - exams scheduling (both internal and external)
      - subject scheduling
      - producing cover/substitution plans for teachers who are absent.
    - - availabiliq, of teachers
      - availability of rooms for each subject
      - nurnber of hours for each subject
      - subjects
        
        subject clashes (..g. o student wishing to do Flench from a group containing
        
        French, History, English and Spanish finds this clashes with their Art/Music
        
        Iessons and so they have to take History instead of French)
      - making sure double lessons appear for certain practical subjects but ensuring
        this doesn't happen with others.
    - - usirg software to create timetables is that it is quicker
        and less error-prone than the older paper-based systems.
      - easier to try
        'what if' scenarios to ersure the most efficient use of time is utilised.
      - Likewise, tirnetables can be produced to cover classes when teachers are
        absent.
        
        This is often done using the main timetable software since each teacher
        is allocated a class or non-contact time for each of the teaching periods.
    - - In the
      - example above, a teacher would have eithel a class or a 'free period' for each
      - 1.5 hour session. The main subject speciality of each teacher is also stored so that
      - a subject specialist can be used to cover for absent teachers.
- - - - customer logges on to
        the theatre booking website
      - the custon'rer clicks on the performance thelr wish to see
      - the database is then searched to check the availability of the selected seats
      - a date and time is typed in
      - o if the seats are available, the total price is shown + the seatnumbers;this
        shows on another screen on the web page
      - the require d number of seats is also entered
      - if the customer is happy with this, they select CONFIRM on the screen
      - the seating display in the theatre is shown on the screen
      - the seats are now temporarily set at NO LONGERAVAILABLE
      - the user selects their seat(s) by highlighting the actual seats on the screen
        display and then clicks CONFIRNT to go to the next part of the process
      - the customer then enters their personal details or inclicates that they are a
        returning customer (ir which case the website will already have their details)
      - the payment method is then selected and payrnent macle
      - the theatre seats are then booked in the custotner's narne
      - the final details are again shown on the screen
      - how Customer recieves the ticket
        
        an email is sent to the clrstorner which they print out as their proof of
        
        pulchase (this also acts as their printed ticket when they go to the theatre -
        
        an e-ticket)
      - the database is finally updated with the transaction and the seats become no
        longer available .
    - - They prevent double-booking (which could happen in paper-based systems
        which didn't update the system fast enough).
      - The customer gets immediate feedback on the availability of seats and
        whether or not their boolcing has been successful
      - The customer can make bookings at any tirne of the day.
      - The customer's email address allows the booking company to attach 'special
        offers' to them and inform them of such offers automatically
      - It is possible to 'reserve' at seat for a period of time - this allows a customer
        to 'make up their mind' before finalising the booking of the seat
      - o It is usually easier to browse the seating plans (particularly on flights) to
        choose the best seats available at the price
      - Very often there are no printed tickets which saves postal costs and also
        allows 'impulse' bookings only a few hours in advance
      - Online booking allows the use of modern smartphone and tablet apps
        technology;
        
        the customer is sent a QR code which contains all the booking
        information necessary
        
        this QR code is stored on the smartphone or tablet and
        only needs to scanned at tlÌe theatre or cinema on arrival)
        
        This removes the
        need to print out tickets (which can get lost) and also removes the probabillity of forgeries
    - - The setting up and maintenance of online booking systems is expensive.
      - It is often more difficult to cancel the booking and get your money back
        using online systems
      - All customers using this service need access to a computer and a reliable
        internet connection
      - If the server is ciown for maintenance or if the systems breaks down, it
        becomes impossible to book seats by any method (a temporary paper-based
        system can't be used because of the risk of double-booking occurring).
      - If the websites are not well designed, it can be difficult to make exactly the
        booking you want or can lead you to make mistakes;
        
        this is a particular issue with
        flight bookings where correcting an error can cost the customer an additional fee
      - Booking online does not allow you to build a personal relationship with the
        travel agent who might offer free upgrades or special offers which may not be available to online bookings
