Although I have tried to check and correct grammar errors and typos, I am sure the manual may still have many. I will continue to improve it and apologize for any inconvenience that may cause to you. Discuss the similarities and differences between these definitions. Below are five definitions of software engineering including the one in the text- book, listed chronologically.
The similarities and differences are shown in Figure 1. A better solution should also provide a convincing explanation of the differences, and significant im- plications of the differences. For example, software engineering education, and significant improvement of software PQCT are important considerations of software engineering. Brugge and Dutoit. Software engineering is a modeling, problem-solving, knowledge acquisition, and rationale-driven activity.
Bernd Brugge and Allen H. Discuss how they improve software PQCT. This sample solution includes the main points. Its functions include identification of business needs, conducting feasibility study, formulating capabilities that the system must deliver as well as design, implementation, testing and deployment of the system to the target environment.
The functions of software quality assurance SQA include definition of quality assurance standards and procedures, and verification, validation and testing activities to ensure that the development process is carried out properly, and the software artifacts produced by the development activities meet the software requirements and desired quality standards.
Soft- ware project management oversees the control and administration of the development and SQA activities. Its functions include effort estimation, project planning and scheduling, risk management, and project administration.
These activities ensure that the software system is delivered on time and within budget. These are the software, or part of it, under different stages of the development process. These documents depend on each other, object oriented software engineering david kung pdf download. This implies that changes object oriented software engineering david kung pdf download one document may affect other documents, which may need changes as well.
Software configuration management SCM is a mechanism to coordinate changes to ensure that changes are made consistently and cost-effectively. These could lead to improvement of software productiv- ity and software quality while at the same time reduce software costs and time to market.
SQA ensures that the software meets the requirements and quality standards. It contributes to improvement of software quality. This in turn reduces rework and field-detected bugs; and hence, it also improves software productivity, reduces costs associated with rework and fixing field-detected bugs.
Software project management ensures proper planning and administra- tion of the software project. In particular, it should request the needed resources to develop the software system, properly schedule the development activities and SQA activities, man- age budget and risks.
These indirectly contribute to improvement of software productivity and software quality. Proper planning and administration of development and SQA activ- ities directly contribute to reducing software development costs and time to market. This is because these activities could be performed smoothly, e. It ensures that components of the software system are constructed and modified consistently and cost-effectively. Consistent modification implies productivity and quality, and cost-effectiveness implies reduction in cost and time to market.
See Exercise 1. Briefly explain, and justify your answer with a practical example. The database access example discussed in Section 1. Optimization could be a focus for a given project. For example, the construction of a compiler for multicore computers. In this case, it depends on whether the project is classified as a software engineering, or a computer science project. It might be an SE project. For example, it is constructed for a certain application.
See solution to Exercise 1. Show the usefulness of these courses in the software life-cycle activities.
An Algorithms and Data Structures course is useful in the implementation phase for the design and implementation of algorithms and data structures to implement business processes. In particular, the course lets the student know the available algorithms and related data structures.
The computational complexity lets the student select appropriate algorithms and data structures according to the nature of the computation. A Database Systems course is useful in the analysis, design, and implementation phases. In the analysis phase, it helps the student object oriented software engineering david kung pdf download database related requirements such as the need to support multiple databases for some applications.
In the design phase, the course enables the student to design the database to fulfill the requirements and constraints. In the implementation phase, the course provides the student abilities to store and retrieve information with a database. A Discrete Mathematical Structures course is useful in many phases of the life cycle.
Graph theory helps the student understand design diagrams such as UML diagrams because UML diagrams are directed graphs. Thus, concepts and algorithms of graph theory can be applied.
Examples include fan-in and fan-out of a class, transitive closure for computing the change impact of a class, traversal algorithms for calculating reachability in a state diagram. Courses on programming languages are useful for implementation, testing, and SQA activities.
Network courses are helpful in SE project that must communicate with a remote computer, such as accessing a remote database. For example, more time and effort spent in coding could increase productivity. This may result in less time and effort in software quality assurance because the total time and effort are constants. Poor quality could cost productivity due to rework. Identify three pairs of such interdependencies of your choice. Discuss their short-term and long-term impacts on the software development organization.
Barry Boehm in his papers on software engineering economics pointed out that the cost to fix a requirements error increases exponentially with time. That is, removing errors as early as possible is a cost-saving effort.
This also coincides with the philosophy advocated by agile methods — that is, test early and often. This reduces bug fixing costs exponentially. This should significantly reduce the error rate; and hence, it reduces the cost that would otherwise have to be spent to fix the bugs.
In the short term, implementing and executing an SQA framework may reduce productivity, increase costs and time to market. However, in the long term, quality software brings many benefits to the organization. These include significant reduction in error rate and error cor- rection costs, customer satisfaction, and increase in software capability maturity level.
These should positively impact productivity, cost and time to market. One should be aware that quality is not the more the better.
Discuss whether OO software engineering will replace conventional software engineering. The main difference between conventional software engineering and OO software engineering is paradigm shift — that is, how object oriented software engineering david kung pdf download view the world and systems. Because of this, object oriented software engineering david kung pdf download, they differ in the basic concepts, basic building blocks, and starting point for the conceptualization, design and implementation of software systems.
Will OO replace the conventional paradigm? The answer should be no1. Such a solution should also be considered a good solution. It is very costly and risky to replace these systems. Therefore, the other paradigms will continue to exist because bug fixing, performance improvements, and functional enhancements to these systems are required.
There are hundreds of thousand organizations and millions of software developers using only the conventional paradigms. It is practically impossible and unjustifiable to require them to convert to the OO paradigm. A conventional paradigm may be more suitable for some projects. For example, scientific computing typically involves series of transformations of input into output.
Therefore, the function-oriented paradigm is more suitable for such applications. Moreover, scien- tific computing emphasizes computing speed, the ability to solve complex computation problems, and the accuracy of the result. OO programming languages may not sat- isfy such requirements. These and the facts that scientific computing is there to object oriented software engineering david kung pdf download and expand into computational sciences imply that the function-oriented paradigm will continue to exist.
In addition to the above, one should know that different parts of a system object oriented software engineering david kung pdf download be developed using different paradigms. For example, a subsystem that performs scientific computing may be developed using the function-oriented paradigm.
A database subsystem may be developed using the data-oriented paradigm, object oriented software engineering david kung pdf download. In practice, there are systems that are modeled and designed using the OO paradigm but implemented in a non-OO language. Identify and explain three advantages and three disadvantages of each of these two models. The waterfall model and the Unified Process UP model are similar in the sense that they are process models, they define phases, the activities and products of each of the phases.
