Open source software is that by which the source code or the base code is usually available for modification or enhancement by anyone for reusability and accessibility.
Open source code is the part of software that mostly users don't ever see. The Rapid Application Development or RAD model is based on prototyping and iterative model with no or less specific planning. In general, RAD approach to software development means putting lesser emphasis on planning tasks and more emphasis on development and coming up with a prototype.
In disparity to the waterfall model, which emphasizes meticulous specification and planning, the RAD approac. Pseudocode is an informal way of programming description that does not require any strict programming language syntax or underlying technology considerations. It is used for creating an outline or a rough draft of a program. System designers write pseudocode to ensure that programmers understand a software project's requireme.
Software maintenance is a part of Software Development Life Cycle. Its main purpose is to modify and update software application after delivery to correct faults and to improve performance. Software is a model of the real world. When the real world changes, the software requires alteration wherever possible. Description: Software maintenance is a vast activity which includes optimization, error. The spiral model is similar to the incremental development for a system, with more emphasis placed on risk analysis.
The spiral model has four phases: Planning, Design, Construct and Evaluation. A software project repeatedly passes through these phases in iterations called Spirals in this model.
Description: These phases are - Planning: This phase starts with the gathering of business requireme. The Prototyping Model is a Systems Development Methodology SDM within which a paradigm output or an early approximation of a final system or product is constructed, tested, and then reworked.
It is done till an appropriate paradigm is achieved to help develop the entire system or product. This model works best in situations when all the details or requirements are not known well in advance. Systems design is the process of defining elements of a system like modules, architecture, components and their interfaces and data for a system based on the specified requirements. It is the process of defining, developing and designing systems which satisfies the specific needs and requirements of a business or organization.
Description: A systemic approach is required for a coherent and well. To prevent incorrect operation of a software or system, debugging is used to find and resolve bugs or defects. Basically, you need to stop the top-down process when you are getting to areas you are not sure about.
Once you get to those areas, start with the bottom-up approach. This lets you try different things, verify with the customer if it makes sense to them, and continue to improve over time.
A detailed design allows you to evaluate design options prior to actually implementing them. It can potentially save you a ton of needless work you would otherwise have spent on an implementation that was deeply flawed due to a high level design choice and had to be extensively rewritten.
When most people talk about detailed design, they are referring to a process known as top-down design. Sign up to join this community. The best answers are voted up and rise to the top.
