In short, this book contains everything that turns a programmer into a software engineer.
While programmers simply code, software engineers have the ability to understand and execute all aspects of development.
Creating complex, intangible, and ever-changing software collaboratively requires engineering, much like constructing a building.
Engineering means the ability to work without failure by understanding and applying principles such as procedures, methods, design, testing, and quality.
It is difficult to create a software system using only an individual's coding skills.
This book is designed to help third- and fourth-year college students learn the basics of software design, development, and operation.
It includes all the following fundamentals presented in the Software Engineering Body of Knowledge (SWEBOK):

- Life cycle and development process to understand the overall picture of software design, development, and operation.
- Project management to understand and control software development plans and development processes.
- A technique for identifying, analyzing, and specifying user needs
- Techniques for modeling software from various perspectives
- Basic software design principles and concepts
- Architecture design, the skeleton of software, and design patterns of object-oriented programs
- Coding methods and various testing and verification techniques to improve quality
- Software quality concept and quality assurance activities to improve quality, product measurement, and process improvement.

To master the diverse and extensive range of software engineering techniques, you must have a good understanding of the basic concepts.
Starting from programming, difficult concepts such as design, modeling, process, and management are explained in an easy and systematic way with illustrations.
This book explains the procedures, methods, and tools for developing software using modern programming languages.
In particular, it introduces UML as a design and modeling representation method, design patterns that can be usefully applied to the programming process, and an agile process that reduces burdensome documentation work and focuses on coding and testing to develop software.

The expected readers include not only students taking major courses at university, but also engineers working in industry who want to improve their job skills.
From concepts and basic theories to practical applications, methods, tools, procedures, report formats, tests, etc. are explained using specific examples.

For the past 30 years, this book has served as a benchmark not only for students studying software engineering in Korea, but also for engineers in industrial settings, public institutions that commission and manage projects, and various tests that verify developers.
Therefore, among the various theories, methods, and tools covered in software engineering, we have continuously added and supplemented the latest technologies that developers need to know.
This book has tried to cover everything about software engineering, from understanding basic concepts to acquiring world-class software engineering skills and preparing for various qualification and employment exams.

What's added or changed in the revised edition

- The agile methods and processes that are increasingly being applied recently are described in more detail in Chapter 2 to reflect the trend.
- The technology for building servers is constantly and rapidly developing, and its design theory is also rapidly evolving.
It is developed in the form of a component-based assembly based on object-oriented design principles.
Therefore, component composition principles including clean architecture were added to Chapter 6.
- UX/UI is also being greatly influenced by the emergence of various interfaces and terminals and the advancement of client coding techniques.
This is reflected in Chapter 8.
- Continuous deployment and operation are required in a cloud operating environment.
Therefore, DevOps concepts, ranging from test automation to automated build and deployment, were added to Chapter 11.
- We have supplemented the content and introduced the latest past exam questions so that you can prepare for not only the Information Processing Engineer Exam and Civil Service Exam, which have been changed based on the NCS (National Competency Standards), but also the Information System Supervisor and Technical Engineer Exams.
