With the rapid development of computers since the beginning of the twentieth century, computing systems and software applications continue to evolve at an incredible acceleration. However, software systems play a central and supporting role in almost all aspects of our daily life. For example, communication structures, production lines and processes, banking and finance systems, education, transportation, entertainment, medicine, agriculture and law are some of these areas. Therefore, with the digitalizing world, computer programs' number, size and application areas have grown dramatically. Quality and low-cost software products help us be more efficient and productive. Quality software provides information, allows us to solve world problems more effectively, and gives us safer, more flexible and less restrictive environments for work, entertainment and recreation.
Despite the incredible benefits that software provides to us; Due to the reasons such as the fact that the software is now very complex, it can contain errors because human hands write it, and the classical design methods are insufficient in software development processes; many software products face severe problems in terms of development costs, timing and quality.
By dealing with issues such as software application design, development, testing and maintenance, a software engineer creates quality, inexpensive and efficient software solutions for end users by using engineering principles and superior programming knowledge that software engineers have had.
