Fundamentals of Software Engineering Introduction: The first usage of term 'software engineering' was in 1968 at a meeting held to discuss the issue that was called software crisis at that time. This crisis was the basic reason to develop a new concept which was called later software engineering. Software systems that were developed before applying the software engineering concepts were not appropriate enough for customers and companies. As a result, software engineering has taken a place in developing large systems. The purpose of applying software engineering approaches is to develop new software systems without any drawbacks. (Sommervile, 2006) The purpose of writing this essay is expressing the fundamentals of software engineering in the developing software environment; also explaining the importance of this kind of science in computing aspects; another point in this study is to identify the measures which help developers to release a successful products. This essay will outline some basics that are related to software engineering science; this essay explains some definitions of software engineering and the reasons that have made software engineers care about using some approaches to deal with developing software. Moreover, this essay will describe the roles that should be taken by software engineers and describe the most important model that has been used to develop software. - The definition of software engineering: Sommervile says "software engineering is an engineering discipline which is concerned with all aspects of software production".

Software design and development is a field that requires various skills and abilities. Companies engaged in the development of software should provide an inclusive work environment where the different strengths of their employees are recognised, utilised and respected. Software development involves far more than programming skills. Personnel are required with strong communication, teamwork, attention to detail, creativity, design and problem-solving skills. Different personnel will possess these skills in varying proportions. It is the job of management to foster and encourage the development and enhancement of skills in the workplace.
1.) Based on your own knowledge of some of the application types discussed in class(lecture 1), explain, with examples, why different application types require specialized software engineering techniques to support their design and development.
Because of complexity and the way it (project) is too long each team member is assigned a task, making code for each programmer not to be too long. Both unit and module testing are accomplished here by software developers. The computer language like C++, Java, Pascal, COBOL and other programming languages is used for coding. On receiving system design documents, the work is divided in modules and actual coding is started. Since, in this phase the code is produced so it is the main focus for the developer. This is the longest phase of the software development life
1.0 IntroductionIn this report I will be concentrating on the failure of software systems. To understand why software systems fail we need to understand what are software systems. Software systems are a type of information system. This is because a software system is basically a means for hardware to process information. Flynn’s definition of an information system is:"An information system provides procedures to record and make available information, concerning part of an organization, to assist organization-related activities."Humans have been processing information manually for thousands of years, but with the vast increase of demand for knowledge this century has meant that a new method of information processing has been needed. Software systems have provided a new means that is much faster and efficient.
Relentless innovation in the way businesses apply computing power to automate business processes has translated into incredible gains in just a few short decades. These innovations have had positive influence in the models used by businesses for delivering software applications to their users. The software application delivery models have evolved over the years starting with the on-premises application delivery whereby application software was installed and operated on a computer located on the premises of the software licensee, rather than at a remote facility. This is the model that drove and defined the first generation of business application delivery which was used before the widespread availability and affordability of the Internet. On-premises delivery model has its limitations which include its inability to support remote access to the application and the cost associated with the initial application setup, the ongoing support and maintenance cost (Aditya, 2012).
While developing a software many complex activities are required which in turn have dependencies along them. Large software projects require the involvement of programmers, documentation specialists, program managers, architects, database analysts, system analysts, , and trainers and last but not the least testers. Along with their independent responsibilities these persons are also responsible to maintain and keep a check on the software system quality as well.
Software Validation and Verification A. Concepts and Definitions Software Verification and Validation (V&V) is the process of ensuring that software being developed or changed will satisfy functional and other requirements (validation) and each step in the process of building the software yields the right products (verification). The differences between verification and validation are unimportant except to the theorist; practitioners use the term V&V to refer to all of the activities that are aimed at making sure the software will function as required. V&V is intended to be a systematic and technical evaluation of software and associated products of the development and maintenance processes. Reviews and tests are done at the end of each phase of the development process to ensure software requirements are complete and testable and that design, code, documentation, and data satisfy those requirements. B. Activities
A Study of WaterFall, a Software Development Model According to en.wikipedia.org Waterfall “is a software development model first proposed in 1970 by w.w. Royce, in which development is seen as flowing steadily through the phase of requirements analysis, design, implementation, testing, (validation), integration, and maintenance”. Waterfall method is the first published model of a software development process (1970). The basic principle is that the different processes (Analysis, Design, Coding, and Testing) are done sequentially. Output from one process is input to the next. Waterfall method advantages like simple, easy to understand and work with.
There is many software development methodologies exist that is used to control the process of developing a software system. No exact system was found which could help the software engineers for selection of best software development methodology. This paper present the framework of expert system combined with Likert scale. With the help of Likert scale we create a rule based model and assign some weighted score to each methodology and develop a tool named as ModSet which will help the software engineers to select an appropriate development methodology that may increase the probability of system success.
The definition for Application software is a subclass of computer software that employs the capabilities of a computer directly and thoroughly to a task that the user wishes to perform (http://www.sciencedaily.com/articles/a/application_software.htm). Applications software comprises programs designed for an end user, such as word processors, database sy...
Software engineering encompasses various principles from both the computer science field and the computer engineering field to develop practical uses of software within hardware we use on a daily basis. With the passage of time, technology dependent on software has become increasingly prevalent. As a result, there will be a high demand for software engineers to sustain the eventual abundance of new and more complex computers.
Waterfall model cannot be tracked back. It is used for large projects. It was purposed by computer scientist Winston Walker Royce in 1970.
Object-Oriented programming (OOP) entered the software development; it shows how software was developed. Developers could visualize systems as groups of entities and the interaction between those entities, which allowed them to tackle larger, more complicated systems and develop them in less time than ever before. The only problem with OO programming is that it is essentially
A software development methodology is a framework that is used to structure, plan, and control the process of developing an information system. There are different software development methodologies which are used for different reasons.
Software engineering is important in today’s society because we use the products of software engineering almost daily. We use the products of software engineering in objects as simple as our car keys to objects as complicated as supercomputers. The past, present, and future of software engineering is quite interesting. This paper will provide information about this field of study and why software engineering is going to be around a while.
