Explain the relationship between Analysis, Design and Implementation for an e-commerce site.
1 Design 1. Not Physically 2. Evaluation is cheap and quick 3. Needs experts 4. Layout is build up 5. Review is done 2. Implementation 1. Physical artifacts. Implementation is the process of realizing the design as a program. 3. Chapter 7 Understanding the relationships between the software that is being designed. The implementation stage of software development is the process of between system components and, sometimes, the algorithms used.
What do design and implementation mean? - Software Engineering Stack Exchange
Services are allocated to components and the interfaces of these components are designed. The data structures used in the system implementation are designed in detail and specified.
The algorithms used to provide services are designed in detail and specified.
Implementing the System or Software Development: Development of an executable program to implement the designed system is actually programming to write source codes. There is no specific rules for programming.
However, at the end of the development of a part, developers do test and debug the finished product. In particular, I will be exploring this question: Indeed, in the last few years new schools of thought have emerged in the design field. Pioneered by developers seeking to improve their ability to deal with complex software building projects, agile methodologies embed in their process several principles common to pattern languages and per- maculture approach: Interestingly Ward Cunningham, inventor of the wiki and one of the main actors of the extreme program- ming methodology and the Agile Manifesto was directly influenced by Alexander p.
In the field of software, Alexander is regarded as the father of the pattern language movement.
No wonder Agile is over with Alexander in our diagram — Alexander was a formative influence in its very creation! I believe I found it. We propose a radical shift in the burden of design and implementation, using concepts adapted from the work of Christopher Alexander, an architect and founder of the Center for Environmental Structures.
On the Relation between Designing and Implementing in Permaculture – Part 8
Alexander proposes homes and offices be designed and built by their eventual occupants. These people, he reasons, know best their requirements for a particular structure.
We agree, and make the same argument for computer programs. Computer users should write their own programs. The idea sounds foolish when one considers the size and complexity of both buildings and programs, and the years of training for the design professions.
Yet Alexander offers a convincing scenario. These activities also occur before the system becomes live in final implementation phase.
Consider the diagram given below which summarize the sequence of activities in the form of a Gantt chart. Although analysis, design, implementation and maintenance activities were considered as separate in systems development life cycle, but there is a great degree of overlap between these phases and all occur simultaneously as a part of evolutionary prototyping approach.
On the Relation between Designing and Implementing in Permaculture – Part 1
While analysis and requirements is in progress, design and implementation will be occurring simultaneously in order to produce storyboards and prototypes. Once the system is live, measurement and review will commence.
As soon as the system is live it will be necessary to make minor updates continuously to the content and services. For each update, a small scale prototyping process involving analysis, design and testing will occur.
