   The Case - Go “MOBILE” Locker is coming to the campus. 
   The CEO of Go Locker has decided to explore the deployment of “MOBILE” lockers 
   to Nanyang Technological University (NTU). 
   With Internet making online shopping experience easy and enjoyable, the use of self service lockers has become popular and a possible business opportunity for Go 
   Locker to service students studying in big campus like NTU. 
   Currently in NTU, students can only one locker at a fixed location. However, with 
   student studying different modules each semester, not all lecture halls and classrooms 
   can be close to the locker location. Hence, a fixed location locker make it 
   inconvenience and troublesome to access, due to “tourism” and heavy human traffic 
   between lesson. 
   Combining the use of electric track transport system (not-in-scope), student can 
   access their “MOBILE” locker at any available Go Locker stations. For example, 
   students can request to “send” their lockers to a station nearest to their next lesson, 
   collect and store items before next lesson. 
   In the pilot phase, Go Locker will allow student to rent up to 2 lockers, at $2 per locker. 
   Student can release/return the locker anytime. Each request to move locker to a 
   specified station will incur 20 cents. When a locker is moved to the specified station, 
   student can proceed to access/open the locker. 
   As an intern in IMDA (Infocomm Media Development Authority), your supervisor has 
   assigned you to help Go Locker with this pilot project, with objectives to automate the 
   mobile locker rental and operations processes. 
   Project Requirement 
   After extensive discussions, Go Locker would like to have the following essential 
   features to be included: 
   System Admin functionalities that featured creation of station, locker, 
   updating of locker details, and reports for station, locker usage. 
   Station Operations/functionalities that include rent/return locker, request 
   locker moves, enquiring locker location and viewing of usage report. 
   Further features to be integrated in the application are configurable rental 
   fees, moving fees, and a background program to process the “moving” of 
   lockers (see BONUS features). 
   Based on you understanding, the pilot project will have 2 applications: one to allow 
   Go Locker administrators to perform administrative functionalities, and the other for 
   students to perform locker operations. 
5. Go Locker – Admin 
   For the Go Locker administrators, the application should display the following 
   menu: 
   ^^^^ Go Locker - Admin ^^^^ 
6. Setup station 
7. Create locker 
8. Update locker 
9. View station report 
10. Track locker usage 
11. Exit 
    Enter option: 
    Before presenting the menus, your application needs to load/pre-setup the 
    stations, lockers, students from Appendix A and rentals (if any) into collections*. 

• Your group can decide to implement using either Dictionary or List. 
  a. Setup station 
  This function allows the administrator to setup a new station. 
  
  To setup a new station, the following data elements should be collected: 
  Station Code: should be unique, in format of NTU-XXX-DD, where XXX 
  represents the building code (e.g., N21, S32), and DD represents digits 
  from 00 to 99. 
  Station Name: name description of the station (e.g., The Hive level 1, The 
  Arc level 2) 
  Rows: number of rows for this station 
  Columns: number of columns for this station 
  Status: Open or Closed 
  The maximum number of lockers for this station will be Rows X Columns. 
  Hence if station NTU-S32-01 has 4 rows and 20 columns, the capacity for 
  this station is 80 slots. Therefore, your application may need to include a 
  collection to represent the 80 slots. These slots will be empty, until student 
  request to move their locker into the station. 
  When a new station is 代写CA3 Diploma in Information Technology  created, the status should be defaulted to “Open”. The 
  new station will be added into the collection and updated into “Stations.txt” 
  file. 
  b. Create locker 
  Locker can be added into the system to meet the demand. To add a new 
  locker, these data elements should be collected: 
  ID: starting from 10001, increment by 1 for each new locker created 
  Location: “Central store”, “In transit”, or any valid station code. Defaulted 
  to “Central store” at creation. 
  Row: default to empty/zero unless the locker is in a station. 
  Column: default to empty/zero unless the locker is in a station. 
  Status: “Occupied”, “Available” (default), “Suspended”. 
  Rental ID: if “Occupied”, need to record the rental ID. 
  When a new locker is created, then locker should be added into the collection 
  and updated into “Lockers.txt” file. 
  c. Update locker 
  The “Update Locker” option allows the administrator to update the locker’s 
  details: 
  User should first provide the locker ID to search. 
  If there is no locker with this ID, display appropriate error message and 
  return to menu. 
  If the ID is valid, your program should display the locker details, and if 
  occupied, the student ID, student name and date started renting this 
  locker. 
  Only allow update to Location and Status. 
  However, status can only be updated to “Suspended” when current Status 
  is “Available”. When updating Status from “Occupied” to “Available”, the 
  rental record needs to be terminated. 
  Any updates should also be affected into “Lockers.txt” 
  d. View station utilization report 
  The option allows the administrator to view the current station utilization. 
  User should first provide the station code to search. 
  If there is no station with this code, display appropriate error message and 
  return to menu. 
  If the station code is valid, your program should display the station details, 
  and a table showing all the slots (rows x columns) – with locker IDs for 
  those slots that contain the students’ lockers. 
  e. Track locker usage 
  The option allows the administrator to track the operations of a specific locker.
  User should first provide the locker ID to search. 
  If there is no locker with this ID, display appropriate error message and 
  return to menu. 
  If the ID is valid, your program should display the locker details, and if 
  occupied, the student ID, student name and date started renting this 
  locker. 
  Your application should ask for the Date-From and Date-To, before 
  generating the report containing all operations for this locker during the 
  specified dates. 
  Below is a demonstration of the generation of “Track locker usage” report:

  a. Rent a locker 
  To rent a locker, students only need to provide their student ID. 
  If the ID is valid, your program should display rented locker details (if any), 
  and if student is renting 2 lockers now, display appropriate error message 
  and return to menu. 
  If student can still rent a locker, your program will locate an available 
  locker and create the rental transaction, charging $2 to the student 
  account. 
  Rental transaction should include the locker ID, student ID, start date and 
  end date (default to None, until the rental is terminated). 
  Your program should generate a unique Rental ID (running number) and 
  display the rental details.

    To show your ability in coding, your supervisor gave you the flexibility to design the 
    structure and interface. Now, you shall apply what you have learnt in the school into 
    practice. 
    More (BONUS) features for consideration: 
    You should explore problem solving techniques to design a solution to allow: 
    a. Dynamic, configurable setup of rental fees and moving fees. Aim is not to re code and restart application for any changes to rental fees and moving fees.
    b. Have a background program processing the locker move requests. 
     When a student request for a locker moves, this transaction will be 
    recorded and processed by your background program. 
     The locker location will be updated accordingly after 3 min, simulating the 
    movement of the locker vis the electric track delivery system. 
     Hence, it will be “In transit”, follow by e.g., “NTU-N32-11” after 3 min. 
     Locker move requests can also be initiated by the system, 30 min after 
    the locker has arrived at a station. This is to manage space/slot, ensuring 
    there are slots at each station to serve students.
