1 Course 254 451 Software Engineering SE Overview and Introduction

2 (c) Michael Brueckner 2005-2006 2 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

3 (c) Michael Brueckner 2005-2006 3 Software  Software comprises รวมถึง computer programs and data plus technical descriptions used to run the programs.  Def. 1957 (John W. Turkey): Software is everything in a computer which is not hardware.  In legal เกี่ยวกับกฎหมาย / ได้รับอนุญาตตาม กฎหมาย view software is intellectual work ทรัพย์สินทางปัญญา

4 (c) Michael Brueckner 2005-2006 4 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
