...Component based software engineering is a development procedure which divides a system into modules and combines them to form a larger system. It is based on the notion that there is a library of first and third party components which are certified that the developers can use to create their desired functionality. These certified components should be based on a standard where developers can easily rely on similar assumptions made by them about each component. CBSE method aims and helps in reducing the cost of software production and by improving the quality of a system by building it and using selected components for its development and integrating these components together into well-defined software architecture which will be one-pieced employed architecture. The components used are different in terms and aspects of programming language and can be developed by different programmers which can significantly improve the communication within a team and in the productivity of facilities.

...Term paper On Design patterns Advanced topics in software engineering CSC 532 Submitted by:- Harpreet Singh Abstract:- Design patterns, a standard solution to problems in object oriented software engineering, are considered to be a well formed language to represent software design. Their benefits have been widely acknowledged by software professionals throughout the world. Design patterns can be classified according to multiple criteria the most common being the type of problem they solve. Till today many design patterns have been established and many more are being found as time passes. Patterns capture knowledge from various parts of software developing. Design patterns are helpful to the designers in a way that they represent the collective wisdom and experience of the community and their implementation leads to better quality software and also a novice designer does not find it difficult to understand the systems functionality. A very important advantage of design patterns is the fact that they speed up the development process by providing an almost ready-made solution that has been used earlier and proved to be efficient. Another advantage is that they allow for a generalized solution that does not depend on understanding a specific design problem from all its aspects, and thus ease reusing this solution. Apart from that they help the new developers to ignore traps and pitfalls which have earlier been learned by other developers by costly experience...

... MBA (HHM) Introduction of case study:- This case study is about software performance engineering, which was applied in hospital information management system to reduce response time. Software Performance Engineering (SPE) is a systematic, quantitative approach to the cost-effective development of software systems to meet performance requirements. SPE, a software-oriented approach, focuses on architecture, design, and implementation choices. This process is mainly used to avoid any discrepancy in the final product as it tries to eliminate error while designing and production of proposed product only. In this case study through software performance engineering response time was reduced by 1.25 second this improvement was achieved because of list processing of bio tests and medicine order, as they were sending test order and medicine prescription in form of bunch. And another feature of this upgraded software was that it setup its connection in advance i.e. prior to operator clicks for registration. Response time reduction at each stage will ultimately result in more satisfied customer for hospital. Response time is an important parameter for the evaluation of performance and reduction in this will result in elevated performance level of hospital. This case study also mentions some of the advantage of using hospital information system like it enables...

...STUDY ON EVOLUTION OF SOFTWARE Introduction Computer software, or just software, is any set of machine-readable instructions that directs a computer's processor to perform specific operations. The term is used to contrast with computer hardware; the physical objects carry out the instructions. Hardware and software require each other and neither has any value without the other. The first theory about software was proposed by Alan Turing in his 1935 essay Computable numbers with an application to the Entscheidungsproblem (decision problem). Colloquially, the term is often used to mean application software. In computer science and software engineering, software is all information processed by computer system, programs and data. The academic fields studying software are computer science and software engineering. The types of software include web pages developed in languages and frameworks like PHP, Perl, JSP or ASP.NET and desktop applications like OpenOffice.org, Microsoft Word developed in languages like C, C++, Objective-C, Java, C#, or Smalltalk. Application software usually runs on underlying software operating systems such as Linux or Microsoft Windows. Software (or firmware) is also used in video games and for the configurable parts of the logic systems of automobiles, televisions, and other consumer electronics. Software evolution is the term used in software engineering (specifically software maintenance) to refer to the process of developing software initially, then repeatedly...

...Aneshia Price English 1101 Paper 3 Draft 2 Problems of Software Engineering The world of software engineering is a dynamic one. There are many benefits of the field including high rate of pay and wide availability of jobs. However, there is always a downside of everything great. Besides the years of rigorous training, there are problems once you enter the field. If you ever need to change jobs, it will be difficult due to the amount of competition (Enriquez). You also have to constantly keep up with changing technology, if you do not keep up the pace, you can easily be replaced. Also, it is a major challenge to just secure a job with a major company like Google. The hiring process is not like a “regular” job. To get a good job in this field, you must be the best of the best and be able to maintain that status to keep your job. There is also an incredible amount of stress related to this job. While it may seem like a cozy inside job, there are many stressor within the software engineering career. The major issue with becoming a software engineer resides in the reason that also makes the field such a successful one. While jobs are plentiful in the field due to changing technology, this also makes it very easy to lose your job. There is always someone waiting to take your place, and since many software engineering jobs allow you to work from home, you have to deal with international competition. Companies are always looking for someone to do the job for less and, “[a]lmost...

Organizations use a standard set of steps, called system development methodology to develop and support their information systems. Like many processes, the development of information systems often follows a life cycle. For example, a commercial product such as a Nike sneaker or a Honda car follows a life cycle; it is created, tested and introduced to the market. Its sales increase, peak and decline. Finally, the product is removed from the market and is replaced with something else. Many options exist for developing information systems, but the most common methodology for system development in many organizations is system development life cycle. However, it is important to know other alternative development methodology available in order to...

...Chapter 1: Introduction 1. Exercise 1.2: What is the most important difference between generic software product development and custom software development? What might this mean in practice for users of generic software products Answer: Generic software product are the stand alone systems that are produced by a development organization and sold on the open market to any customer who is able to buy them. Examples of this type of product include software for PCs Such as databases, word processors, drawing packages, and project management tools. It also includes vertical applications designed for some specific purpose such as library information systems, accounting systems, or systems for maintaining dental records. Customized (or bespoke) software products are the systems that are commissioned by a particular customer. A software contractor develops the software especially for that customer. Examples of this type of software include control systems for electronic devices, systems written to support a particular business process, and air traffic control systems. An important difference between these types of software is that, in generic products, the organization that develops the software specifications. For custom software products, the specification is usually developed and controlled by the organization that is buying the software. The software developers must work to that specification. However, the distinction between these system product types is becoming increasingly...

UML is structured so that it enables scalability, security and robust execution under stressful conditions and the structure must be defined clearly enough so that when an issue occurs, maintenance programmers can quickly find the bug and fix it. When talking about large enterprise applications, these programs must be designed to work perfectly. A well designed architecture benefits any program and not just large ones. The structure is a way of dealing with complexity, so the advantages of structure, and of modelling and design, compound as the application...

Web This article discusses software engineering and the definition of basically what it is, it states that it is concerned with maintaining software systems and developing one that will work correctly and be very dependable for the user, they have to keep in mind as well that there projects need to be affordable and that they assure reliability and they meet all the users needs. The actual article states, “Software engineering (SE) is concerned with developing and maintaining software systems that behave reliably and efficiently, are affordable to develop and maintain, and satisfy all the requirements that customers have defined for them.” (computer machinery) The article talks about how critical it is for the application to be safe especially because of how expensive the software system are. Software Engineering integrates a significance of mathematics in computer science and practices the origins of engineering. This article give a good definition of what software engineering is about, it doesn’t give enough detail on what exactly they are doing everyday its very broad and doesn’t narrow it down. It begins to talk more about how to get into the job itself, instead of focusing on exactly what they do, it gives a description of all the step you need to take to get there. It strays away from what you’re actually doing when you become a software engineer. Furthermore...

...Individual Assignment The two software development methodologies that I have selected for this assignment are the Waterfall Model (as chosen by you) and the Spiral model (chosen by me). These two methods often cause confusion amongst software developers as they are unable to decide which of the two is better for the software they are developing. The first software model to be used was the waterfall. The spiral, that came later, is one of the most popular models in the field of software development. I will go further into each of the above mentioned two models after I describe the four laws given in the prescribed text. I will start with the Glass Law (dubbed law 1). If I was to describe the Glass law, I would say in a nutshell, requirements are the foundation of any project, and incomplete or misinterpreted or misjudged requirements are the key to failure. What I mean by the above is that when the requirements are not clarified, incomplete, unstable or far too many to cope with, the project will face a high chance of failure. A real world example, which added approximately $560M USD to the cost of the airport and became a modern era example of Glass law, was originally planned to automate the handling of baggage through the entire airport, but due to underestimation of complexity, changes in requirements, underestimation of schedule and budget and other causes was a drastic failure. Moving to Boehm’s laws, the first and second law complement each...
