Computer software includes the source code for the get system and all the supporting documents generated during analysis, design, implementation, testing, and maintenance of the system. Internal documentation includes standard prologues for compilation units and subprograms, this document is for software source code, and the internal comments embedded in source code ... Read More

Software measurement Measurement in the physical world can be e categories in two ways: Direct measures Indirect measures Direct measures (internal attributes) Direct measures of the software engineering process involve cost and effort included. Analysis of the product involves lines of code produced, execution speed, memory size, and defects reported over a period of time ... Read More

What is risk Risks are possible difficulties that might affect the successful finish of a software project. Risks involve uncertainty and potential losses. Risk analysis and management are assigned to help a software team to understand and manage ambiguity during the development process. Who does it Managers, software engineers, and customers associate in risk analysis and Management ... Read More

Fourth-generation techniques Fourth-generation techniques encompass a broad array of software tools. The tool then automatically generates source code based on the developer's specification. A software development environment that supports that 4GT paradigm includes some or all of the following tools: non-procedural languages for database query, report generation, data manipulation, screen interaction and definition, code generation, high-level graphics capability, spreadsheet capability, and automatic generation of HTML and languages used for website creation ...

Transform Mapping It is a set of design steps that allows a DFD with transforms flow characteristics to be mapped into a specific architectural style. In transform, mapping is described by applying design steps to an example system a portion of the safe home security software. The Safe Home security system is representative of many computer-based products and systems in use today ... Read More

Transaction mapping In several software applications, a single data item triggers one or more information flows that affect function played by the triggering data item. The data item, call transaction. An example Transaction mapping Vin the Illustrator by considering the user interaction subsystem of the safe home software ... Read More

Software requirements specification (SRS) Software requirement specification at the result of the analysis task. The function and performance designated to the software are filtered by establishing an entire data description, detailed functional description, the presentation of system behavior, an indication of performance requirements and constraints, validation criteria, and others ...

Software Requirements Engineering A bridge to design and construction Designing and building computer software is challenging, inventive. From a software process view, requirements engineering is a software in the business that starts during the communication activity and continuous into the modeling activity ... Read More

Software testing Testing is the process of operating a program with the particular purpose of detecting errors before delivery to the end-user. Testing is a set of actions that can be planned and conducted systematically. Software testing strategies Steps: Testing begins in the small and progresses to the large ... Read More

Software quality assurance Software quality is described as conformance to explicitly state functional and performance requirements, explicitly documented standards and implicit features that are anticipated of all professionally developer software. The purpose of software quality assurance is to deliver high-quality software ... Read More

Software Design A software design is an essential engineering description of some software product that is to be established. A design can be determined to the customer's requirements and can be assessed for quality against predefined patterns. Design specification models Data design - designed by transforming the analysis data model (data dictionary and ERD) into data structures needed to execute the software ... Read More

Software Reuse Building software from reusable components. Objectives To illustrate the benefits of software reuse and some reuse difficulties To define different types of reusable components and processes for reuse. To introduce application families as a route to reuse. Reuse based software engineering Application system reuse The bulk of an application system may be reused either by consolidating it without change into other systems are by generating application families ...

Software Configuration Management When you develop computer software, change occurs, and because it happens, you need to manage it effectively. Software configuration management is a set of actions composed to regulate change, by Identifying the work product that is likely to change Establishing relationships among them Defining mechanism for managing different versions of these work products Controlling the changes imposed and Auditing and reporting on the changes made Need for SCM There are many reasons for implementing an SCM system on a software project, all of which save time, lower costs, and reduce problems ...

Software Reliability It is defined as the possibility of failure-free service of a computer program in a specified environment for a specified time period. Can be measured directly and assessed using historical and developmental data (unlike many other software quality factors). Software reliability problems can normally be traced back to errors in design or implementation ... Read More

The overall structure of the software components and how the success provides a conceptual integrated file system. In other words, architecture is the hierarchical structure of program components, how these components interact, and the structure of data that are used by the components. A set of architectural patterns enable a software engineer to reach design level components ... Read More

Real-time and distributed system design The real-time system is a software system the correct functioning of the system depends on the results produced by the system the time at which these results are produced. Many of the popular design "methodologies" were developed as design techniques for applications programs, operating systems, and related programs (compilers, editors, loaders, etc) ... Read More

Project structure Project format It assembles a team of programmers who conducted a project from start to finish. Team members do product definition, design the product, implement it, test it, conduct project reviews, and prepare the supporting documents. Some project team members may stay with a product during installation and maintenance, and some team members may go on to new projects while retaining responsibility for maintenance of the delivery product ...

Waterfall Model The waterfall model also called classic life cycle requirements is well defined and stable. It suggests a systematic, sequential approach to software development. It begins with customer specification of requirements and processes through planning, modeling, instruction, and deployment ... Read More

Software maintenance Software maintenance is the process of modifying or update the software component after delivery to correct faults to enhance the performance or adapt to the latest changes in the environment. Software maintenance is concerned with modifying software once it is delivered to a customer ... Read More
