Beit 381 se lec 1 - 30 - 12 feb07

  1. 1. SE-381 Software Engineering BEIT-V Lecture no. 1
  2. 2. SE-381 Software Engineering • Course Profile • Integrated Approach to Software Engineering – A Class Project will be incrementally developed by applying the techniques as these are read – 6 Unannounced, surprise Quizzes – all to be considered • From handouts given and from text covered since last quiz • NO Repeats, NO Choices, ZERO-credit for Cheating/plagiarism – 3 Assignments and few mini-assignments (for compensation) • Individual Assignments so ‘individual’ effort expected – Group Project • 2 Presentations – One before Mid-term and other before End-term – Formal Dressing, English, well timed out, in-depth content coverage • Handing in of group project deliverables: Project Plan, Analysis, Design, Testing, Implementation and Final working version of Project – Mid term and Final Exams • Mid-term from course prior to Mid and Final exam from full course
  3. 3. HHI – Human Human Interface • Class Discipline – No • Gossip, whispering or ringing mobiles, exchanging messages • Eating or chewing during class • late arrivals and no early departures • late submissions of assignments and projects • Clustering or Pressure groups especially to hinder academics – Attendance only of those who attend and are in time – Deadlines to be respected religiously – A MUST in Sw Industry. – Class decorum – few protocols and symbols; • Miss-understandings or ‘ponies’, Hold-on, U me and Q, Late Arrivals – ‘thanks’ for coming – CR to take the handouts and organise for extra classes, if any • Good Grades – Need 100% Class Attendance – 100% attention during lecture – listen and take notes – Understand Semester System and start working from day – One – Lecture Transparencies are the lecturing aid, NOT for reproduction in exam
  4. 4. HHI Continued… • Good Grades!! – Ask promptly if confused or not understanding – More effort outside the Class – extra reading at home, practice, benefit from referenced sources and Internet – Please ask and clarify if you are confused, it can help you and others, and can save many of us from later embarrassment (s) – In exams, read and understand questions, reply what is asked • Suggestions/feedback welcome – it helps to improve • Teaching is a Social activity and needs two-way communication / contribution, not possible without knowing each other well – Myself – Would like to know about yourself – Student Profile – will be dealt as ‘confidential’
  5. 5. Computerization – All around • Public Services being computerized for low cost and high output • Public Sector offices – Efficiency, Data Sharing, Security etc. For example NADRA data being shared by Passport Offices, Immigration Dept, Min of Interiors – Arms Licenses, Election Commission, Bureau of Statistics, Banks eg ACBL etc • Businesses - for Customer satisfaction, better management, transparency and low pilferage • Scientific, Engineering and Technology setups – to address complexity, refinement, optimal and efficient solutions
  6. 6. Businesses
  7. 7. Some Examples of Software – Embedded Systems – Mobile phone of the day, MAX V8 MP6 Player – Medical Diagnostic Systems, MRI, CT SCAN, Digitized X-Rays – Inventory Control and Business Systems – Web based systems, www.mustakbil.com (650 K CVs, 300-400K daily hits, and 150- 200K daily mailshots; prev the largest, now 2nd largest), www.rozi.com the largest jobs site of Pakistan as per Nov 2009 – Information systems backed by Google Earth and GIS www.dhakacitymap.com
  8. 8. Hydroponics' Agriculture Farm
  9. 9. Hydroponics’ Agriculture Farm • 5 Acre Land, Near Rawat, off GT Road • 7 Million US$ investment – in 2005 • All machinery imported from Holland and installed by the local team in the supervision of experts from abroad • 20-25 people – Matriculates and DAE holders – locally educated youth with extensive training in its installation and operations
  10. 10. Hydroponics Agriculture Farm - Outputs • Capable of producing – 2 tons of high quality tomatoes or other vegetables a day or 700 tons per annum • Marketing – 65% top quality exported to EU, 30% 2nd grade to Dubai and rest to Metro Islamabad (at the rate of Rs 70 per Kg and Metro sells these tomatoes @ Rs 120 or more to public) – as per Feb 2010 market prices – Tomatoes clusters are sold at higher price – Other vegetables like special quality sweet pepper is much more costly and can grow to a weight of 250 grams per pepper
  11. 11. Metaphor ? • Front end • The way we see it, or it interacts with the users
  12. 12. • Back end • In case of Hydroponics, no soil is used for growing plants, plants are nourished by the nutrients fed to the plants in liquid form. The excess nutrients are drained out, their contents measured, compensated by adding required chemicals and re-fed to the plants • Oxygen, fresh air, temperature, humidity, sunlight, Carbon dioxide etc are all measured, monitored and controlled automatically • Rain water is mainly used as solvent for the supply of these nutrients, it is mixed with ground water to get appropriate Ph level • In case plants need CO2 then in a boiler CO2 is prepared and respective stream is fed
  13. 13. IT - the Brain • Whole system from monitoring of external temp, pressure, humidity, wind velocity and direction etc to nutrients chemical analysis, plants demand, and internal temp, pressure, humidity conditions etc are all monitored • Suggestions for opening of different valves, vents, movement of actuators and sun-sheilds etc are given to operators of the system • Reports for different controls and inputs and outputs are generated • All attributes from water level in tanks, to produce per plant and per Green house are recorded • In ‘Auto’ mode all these controls could be carried out automatically, and in ‘Manual’ mode data for decision making is provided and desired actions are suggested
  14. 14. Mini-Assignment What software or IT-artifact has fascinated you the most? Write down the reasons for you fascination, how useful it is to yourself and general public, and guess what technologies have been used in its development and how much effort might have gone into it for its development. Please hand it in on August 22, 2011 (Monday) in hand written form, no more than 03 pages.
  15. 15. A Retention Exercise
  16. 16. • On provided A5 sheet, – Please write a 6 lettered code (of your own choice) and – On the other side draw the sketch of Faizabad Chowk, mentioning all the roads coming into and emanating from it. • Hand it over in 10 minutes Start Time: _______ End Time: ______
  17. 17. Purpose : How brain works?
  18. 18. • Human brain – Categorizes things differently, as per their retrieval needs • The one that are not important are stored and lost, or these are stored from where these are never retrieved and • The ones that are Important are stored so that they can be easily retrieved when required • The scenario that was portrayed – Has been watched by all of you many times but you never thought that it will be ever asked, – Probably now! You will look at Faizabad Chowk differently
  19. 19. – For example, reading an article for • Fun sake • Examination and • Teaching it to others Will be processed differently, by the brain – For the last choice it will pay maximum attention and handle it with utmost care. If needed, it will instruct you to read, re-read and re-re-read different parts unless these are clearly understood and appropriately stored for retrieval and reproduction before the class – Before moving further, let’s analyze how brain comprehends and makes the judgment
  20. 20. Comprehension and Judgment • It is a three phased process (a) Listening (b) Processing (integration and Analysis) (c) Judgment • Pictorially Listening Processing Judgment
  21. 21. Beware! • Human mind – Concentrates on what is ‘Important’ and ignores what is ‘not important’ – Understands and judges matters strictly in the laid out order i.e. • Listening is Pre-requisite for processing, otherwise it will be processing without factual information, and • Making a judgment without ‘Processing’ or proper synthesis will be a pre-mature judgment
  22. 22. Human Mind – Will be most productive, if the information is • Completely and carefully listened • Thoroughly processed or synthesized with already retained and known information, and then • Judgment is made • Thus
  23. 23. For Best Results • From this SE course (1) Make an intention that you have to use and teach, the read information, to others (2) Pay 100% (yes 100%) attention to what is being taught, any disruption will lead to loss of information and hence will compromise learning (3) Read the referred chapters and given hand outs, it is a MUST (4) Revise occasionally to ensure maximum retention
  24. 24. Reading Assignment 1. Ch-1 Problems and Prospects, pp 3-22 From Douglas Bell (2005); Software Engineering for Students; Pearson Education Limited 2.
