The V-model is a graphical representation of a systems development lifecycle.It is used to produce rigorous development lifecycle models and project management models. The V-model falls into three broad categories, the German V-Modell, a general testing model, and the US government standard.
A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates.

A life-cycle "model" is sometimes considered a more general term for a category of methodologies and a software development "process" is a particular instance as adopted by a specific organization. [ citation needed ] For example, many specific software development processes fit the spiral life-cycle model.
The waterfall model is the earliest Systems Development Life Cycle approach used in software development. [ 3 ] The waterfall development model originated in the manufacturing and construction industries, [ citation needed ] where the highly structured physical environments meant that design changes became prohibitively expensive much sooner in ...
In software development, the V-model [2] represents a development process that may be considered an extension of the waterfall model and is an example of the more general V-model. Instead of moving down linearly, the process steps are bent upwards after the coding phase, to form the typical V shape.
SDLC may refer to: Systems development life cycle or system design life cycle, which is often used in the process of software development Software development life cycle or software development process
In this example, the working of that restaurant is used to understand how UML can be used to implement a restaurant system. Here wait staff take order and serve food to patron. Then patron eat food, drink wine and pay bill. In this diagram patron, chef, cashier and wait staff are actors. Applications of UML in embedded systems
The Zachman Framework is not a methodology in that it does not imply any specific method or process for collecting, managing, or using the information that it describes; [2] rather, it is an ontology whereby a schema for organizing architectural artifacts (in other words, design documents, specifications, and models) is used to take into ...
