Application software suites include everything from a word processor to spreadsheets, image manipulation and drawing. From embedding spreadsheets into word processor created documents to inserting edited images, the possibilities are endless. While application software manipulates data or text to provide information, systems programs are involved in manipulating computer hardware resources. System software forms the basis on which application software operates.
General purpose, off the shelf application programs supporting general types of processing, is referred to as personal application software. Personal application software aims at improving the productivity of individual users. Computer spreadsheet packages can be utilized for financial information such as cash flow analysis or income statements. They are also used to forecast sales, analyse insurance programs, and prepare summaries of income tax information and investment analysis.
Spreadsheets are application software that offers data management and graphical capabilities. Spreadsheets can also be used for applications requiring modeling, simulations and what-if analysis. A spreadsheet can be recalculated, and data management software supports storage and retrieval and manipulation of data.
If the numbers game is not up your alley and words are your true ally, word processing software is definitely for you. This allows users to manipulate text through an integrated set of programs comprising an editor, formatting, print, dictionary, thesaurus, spelling and grammar checker, mailing list, graphing, charting and drawing programs.
Moving past regular word processing, specialized documents such as newsletters, magazines, and journals require the use of desktop software. Rather than putting together documents by hand and getting them typeset, users can perform tasks directly, combining text with rich images to create a perfect final product.
Graphics software packages, including presentation, analysis, and CAD design, can be used to create strong and powerful visuals. Analysis graphics goes a step further, and lets analyzed data to be organized into graphics formats such as:. From sales results to marketing research data, presentation graphics and graphic analysis prove to be simply perfect for the job.
The CAD software is used for designing items for manufacturing. This application software is great for compiling quantity lists, building production prototypes and transmitting the final design based on the prototype. The multimedia software combines two or more media for the input or output of information. Multimedia is a profusion of media, including audio, voice, animation, text, video, images and graphics.
Think of it as a combination of spatial media with time-based media, i. Computers are fairly talkative…. Information is exchanged over dedicated public cables, telephone lines, satellite relay systems or microwave circuits. The USP of this software plays a key role in the function of the ISP by establishing and relinquishing electronic links and coding and decoding data.
Speech recognition is a form of application software that can be divided into two further types- discrete and continuous. While the former recognizes only one word at a time, the latter recognizes multiple.
Chapter 10 of the SWEBOK discusses modeling principles and types, and the methods and tools that are used to develop, analyze, implement, and verify the models. Table 1 identifies software engineering features for different life-cycle phases. The table is not meant to be complete; it simply provides examples. For the purposes of Table 1 the definition of a model is extended to some aspect of the software system or its development.
The idea is that the Project Plan provides a model of how the project is going to be carried out: the project team organization, the process to be used, the work to be done, the project schedule, and the resources needed. A software metric is a quantitative measure of the degree a software system, component, or process possesses a given attribute. Because of the abstract nature of software and special problems with software schedule, cost, and quality, data collection and the derived metrics are an essential part of software engineering.
Highly informative subject and well taught by the instructor. Information security is an extremely important topic in our world today. As individuals, we seek to protect our personal information while the corporations we work for have to protect suppliers, customers, and company assets. Creating secure software requires implementing secure practices as early in the software development lifecycle SDLC as possible.
This Specialization focuses on ensuring security as part of software design and is for anyone with some workplace experience in software development who needs the background, perspective, and skills to recognize important security aspects of software design. Mindsets and attitudes of successful designers—and hackers—are presented as well as project successes and failures.
Always at the core of front-end design will be user experience and you will have the opportunity to ensure clean and effective user interfaces that also serve to provide the best security.
Back-end development topics such as database design are also covered. Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:. When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work.
Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free. Yes, Coursera provides financial aid to learners who cannot afford the fee. Apply for it by clicking on the Financial Aid link beneath the "Enroll" button on the left.
You'll be prompted to complete an application and will be notified if you are approved. You'll need to complete this step for each course in the Specialization, including the Capstone Project.

About this book Introduction Objectives of this Book This book is an introduction to a set of software specification methods. The same case study is used to introduce each method, following a rigorously uniform presentation format.
Special care has been devoted to ensure that specifications do not deviate from the case study text. As much as the method allows, what is specified is what appears in the case study text.
The benefits are two-fold. First, the reader can easily switch from one method to another, using his knowledge of the case study as a leverage to understand a new method.
