There are two different levels at which UML and XML can be mapped: UML can be used to model the structure of XML documents directly. XML schemas can be generated for the purpose of validating the documents, but they are provided as a convenience for application developers. ... UML can be used to model an XML schema.

UML can be used to develop diagrams and provide users (programmers) with ready-to-use, expressive modeling examples. Some UML tools generate program language code from UML. ... UML is a graphical language for visualizing, specifying, constructing, and documenting information about software-intensive systems.

The most used models are Waterfall models used for generally small scale projects and single release based software products, whereas the Prototyping Model is used for developing large scale products generally developed in multiple parts rather than single release also called version of release.

The purpose of FMC diagrams is to facilitate the communication about a software system, not only between technical experts but also between technical experts and business or domain experts. The comprehensibility of FMC diagrams has made them famous among its supporters.

Explanation: There are many data link layer protocols. Some of them are SDLC (synchronous data link protocol), HDLC (High level data link control), SLIP (serial line interface protocol), PPP (Point to point protocol) etc. These protocols are used to provide the logical link control function of the Data Link Layer.

Traditionally, the systems-development life cycle consisted of five stages. That has now increased to seven phases. Increasing the number of steps helped systems analysts to define clearer actions to achieve specific goals. Similar to a project life cycle (PLC), the SDLC uses a systems approach to describe a process.

When talking about an information system, we must recognize that it includes both hardware and software configurations, which is why the SDLC encompasses these two components and usually covers these 7 phases: planning, analysis, design, development, testing and integration, implementation, and maintenance.

VLC works just fine for 99% of files. IMO, MPC-HC is better for tweaking or for super-high bitrate files (and there are forks of MPC for super tweaking). Frankly, unless you have very specific requirements, VLC or MPC works just fine-- both pretty much 'plug and play.

SDLC - Waterfall Model. The Waterfall Model was the first Process Model to be introduced. ... In a waterfall model, each phase must be completed before the next phase can begin and there is no overlapping in the phases. The Waterfall model is the earliest SDLC approach that was used for software development.
