System Engineering Concepts

Software engineering occurs as a consequence of a process called system engineering. Instead of concentrating solely on software, system engineering focuses on a variety of elements, analyzing, designing and organizing those elements into a system that can be product, a service or a technology for the transformation of information or control. Before software can be engineered, the “System” in which it resides must be understood. To accomplish this, the overall objective of the system must be determined; the role of hardware, software, people, database, procedures, and other system elements must be identified; and operational requirements must be elicited, analyzed, specified, modeled, validated and managed. These activities are the foundation of system engineering... browse notes.

System Engineering Process and Design Modeling

System Engineering focuses on a variety of elements. Analyzing, designing and organizing those elements into a system that can be a product, a service or a technology for the transformation of information or control is the basic facet of system engineering. System modeling is an important element of the system engineering process. Whether the focus is on the world view or the detailed view, the engineer creates model that define the process that serves the needs of the view under consideration... browse notes.

Data Design, Arcitectural Design and Component Level Design

The data design action translates data defined as part of the analysis model into data structures at the software component level and when necessary into a database architecture at the application level. Architectural design represents the structure of data and program components that are required to buil a computer-based system. It considers the architectural style that the system will take, the structure and properties of the components that constitutes the system, and the interrelationship that occurs among all architectural components of a system... browse notes.

Web Engineering Practices - Design and Testing

Web engineering applies "sound scientific, engineering and management principles and disciplined and systematic approaches to the successful development, deployment and maintenance of high-quality web-based systems and applications. WebE can be described in three layers - process, methods, and tools/technology. The WebE process adopts thee agile development philosophy that emphasizes a “lean” engineering approach that leads to the incremental delivery of the system to be built. The generic process framework - communication, planning, modeling, construction, and deployment - is applicable to WebE.... browse notes.

Software Engineering Process Patterns Framework, Assessment and Technology

Software engineering is the establishment and use of sound engineering principles in order to obtain economic software that is reliable and works efficiently on real machines. Software engineering is a layered technology. Any engineering approach including software engineering must rest on an organization commitment to quality. The software process can be defined as a collection of patterns that define a set of activites, actions, work tasks, work products and/or related behaviours required to develop computer software.. browse notes.

Software Engineering Process Models

Process models define a distinct set of activities, actions, tasks, milestones and work products that are required to engineer high quality software. These process models are not perfect, but they do provide a useful roadmap for software engineering work. Prescriptive process models were originally proposed to bring order to the chaos of software development. History has indicated that these conventional models have brought a certain amount of useful structure to software engineering work and have provided a reasonably effective roadmap for software teams. However, software engineering work and the product that it produces remain on “the edge of chaos”... browse notes.

Agile Software Process Models and Software Development Methods Variants

In 2001, Kent Beck and 16 other noted software developers, writers and consultants (referred to as te "Agile Alliance") signed the "Manifesto for Agile Software Development." It stated: We are uncovering better ways of developing software by doing it and helping others do it. Agile software engineering combines a philosopy and a set of development guidelines. Although the underlying ideas that guide agile development have with us for many years, it has only been during the past decade that ideas have crystallized into a movement.” In essence, agile methods were developed in an effort to overcome perceived and actual weakness in conventional software engineering. Agile development can provide important benefits, but it is not applicable to all projects, products, people, and situations. It is also not antithetical to solid software engineering practice and can be applied as an overriding philosophy for all software work.... browse notes.
