Course Software Engineering SE Overview and Introduction

(c) Michael Brueckner Introduction to Software Engineering  Terminology คำศัพท์เฉพาะทาง :  software,  software engineering,  software engineers,  software products  Difference ความแตกต่าง between software engineering and systems engineering  Difference between software engineering and computer science

(c) Michael Brueckner Software  Software comprises รวมถึง computer programs and data plus technical descriptions used to run the programs.  Def (John W. Turkey): Software is everything in a computer which is not hardware.  In legal เกี่ยวกับกฎหมาย / ได้รับอนุญาตตาม กฎหมาย view software is intellectual work ทรัพย์สินทางปัญญา

(c) Michael Brueckner Software Engineering  All activities which lead to a software product  Get all requirements  Design the system  Programming  Testing the system  Track the versions  Manage the people

(c) Michael Brueckner Software Engineers  People who apply SE methods  Special Software Engineers  Testing engineers  System analysts  Software designers ...

(c) Michael Brueckner SE vs. CS  Computer Science is the theory of programming  SE is more the practice of doing it

(c) Michael Brueckner Properties of Software  Developed พัฒนา once หนึ่งครั้ง  Maybe in many versions  Can be distributed เผยแพร่ at low cost  CD-ROM / DVD  Download  By „air“  Can be used without waste ของเสีย

(c) Michael Brueckner Software Products-1  Generic โดยทั่วไป products  Customized ซึ่งสร้างตามคำสั่งเฉพาะของ ลูกค้าคนเดียว products  We have to manage versions

(c) Michael Brueckner Software Products-2  Application software  Office programs  Utilities  Multimedia software  Security software  Funware  System software  Operating systems  Drivers

(c) Michael Brueckner Software Development Process  Processes for different types of software  Application development  Operating system development  Embedded software (=programmed HW device)  Maybe different processes  Different customers, users  Different requirement structure

(c) Michael Brueckner Software Development Process Basic Ideas  Requirements – Specification ข้อจำกัด  Development – Implementation ทำให้มีผล  Validation การให้เหตุผล – Distribution  Evolution วิวัฒนาการ – more versions!  Process models ต้นแบบ = simplified ทำให้ ง่ายขึ้น description of SW development
