• Formal Requirements Specification
• Architecture Prototype
• Formal technical inspection letters
• Questions

Action Item(1)Verifications

• - Each student has a unique test number.
• - No recommendation for new students
• - If there is a null level for a student that
  implies there is no grade neither recommendation.
• for new students
• students placement level matches their Excel
  sheet --gt According to the TestNo.
• for returning students
• placement level matches their Excel sheet --gt
  According to the TestNo. and a teacher
  recommendation.

Action Item (2) Forms and Reports

• In my project I will use Crystal Reports for
  Visual Studio.NET to generate reports these
  reports will be printed by the clerk. My project
  scope covers printing students reports, not
  sending them to students by email.

5
Action Item (3) Generating data

• ELP will give me data testing to test my program
  besides using generator data tool to generate
  random data (EMS Data Generator). The tool will
  generate 1000 of record for student information
  and their scores.

6
Action Item (4) COCOMO model estimates

• I followed these steps to estimate the cost and
  the size of the my project
• Determine and count five information domain
  characteristics inputs, outputs, inquiries,
  files, and external interfaces.
• Compute the Function Points following the
  formula
• FP ? UFP ? 0.65 0.01 ? ?(Fi), which Fi are
  complexity adjustment values.
• Calculate the Source Lines of Code with the help
  of the AFP and the Language Factor (LF).
• After that I applied the COCOMO formula for the
  application program.

7
COCOMO model estimates

• The COCOMO formula for the application program
• Delivered Source Instructions (KDSI) 1.7655 K
• Programmer Effort (PM) 2.4 (KDSI) 1.05 4.4
  programmer-month
• Development Time in month (TDEV) 2.5 (PM)
  0.38 4.4 months

Architecture Design for the client application
(Clerk)
The Architecture Design for the client
application is based on a two-tier architecture
which contains of 1- Presentation and Business
Tier 3- Data Tier.

Architecture Design for the web application
(Teacher)
The Architecture Design for the web application
is based on a three-tier architecture which
contains of three logic tiers 1-
Presentation 2- Business 3- Data.

Test PlanType of testing

• Unit testing, using NUnit testing tool.
• Performance testing using JMeter tool.

Formal Requirements Specification

• Constraints
• Each student has a unique test number.
• No recommendation for new students
• If there is a null level for a student that
  implies there is no grade neither recommendation.
• for new students
• students placement level matches their Excel
  sheet --gt According to the TestNo.
• for returning students
• placement level matches their Excel sheet --gt
  According to the TestNo. and a teacher
  recommendation.

24
Formal Requirements Specification (1)

• Each student has a unique test number.
• context Student
• inv UniqueTestNo
• Student.allInstances -gt forAll(S1, S2 S1 ltgt
  S2 implies S1.TestNo ltgt S2.TestNo)

25
Formal Requirements Specification (2)

• - No recommendation for new students
• context s Student
• inv noRecomNewStudents
• s.status new implies s.recommendation -gt
  isEmpty()

26
Formal Requirements Specification (3)

• If there is a null level for a student that
  implies there is no grade neither recommendation.
• context s Student
• inv nulLevelNoGradeNoRec
• s.curr_level null implies s.recommendation-gt
  isEmpty() and s.grade -gt isEmpty()

27
Formal Requirements Specification (4)

• for new students
• students placement level matches their Excel
  sheet --According to the TestNo.
• for returning students
• placement level matches their Excel sheet --gt
  According to the TestNo. and a teacher
  recommendation.

28

• context s Student
• inv Placement
• if s.status new and s.flagImportCurrentSeme
  yes then
• lookup (s.grade)-gtforAll(scsc.l
  curr_level)
• --not a new student
• else
• (lookup(s.grade)-gtforAll(scsc.l curr_level)
  )
• (if sc.l s.placed curr) then
• (if
• (s.recommendation.AchivementScore gt 80)
  ) then
• ( (s.placed newLevel) )
• else
