Prototype model should be used when the desired system needs to have a lot of interaction with the end users. Typically, online systems, web interfaces have a very high amount of interaction with end users, are best suited for Prototype model.

In this model phases are processed and completed one at a time. Phases do not overlap. Waterfall model works well for smaller projects where requirements are clearly defined and very well understood.

There are Four Main Software Prototyping Methods

• Incremental Prototyping.
• Throwaway Prototyping.
• Extreme Prototyping.
• Evolutionary Prototyping.

For example, word-processing software developed using the incremental paradigm might deliver basic file management editing, and document production functions in the first version; more sophisticated editing, and document production capabilities in the second version; spelling and grammar checking in the third version; …

Types Of Software Process Models

• Waterfall Model. The Waterfall model represents a breakdown of software project activities in a linear sequential phase.
• Iterative Mode. An Iterative software development life cycle model does not directly attempt to begin with a full specification of the prerequisites.
• V Model.
• Incremental Model.
• Spiral Model.
• Agile Model.

The process models can be combined because all the processes are about similar to each other as all the models have these basic phases like: requirements gathering, planning, designing, implementation and deployment but each model suggest the different process flow.

“Agile process model” refers to a software development approach based on iterative development. Each iteration involves a team working through a full software development life cycle including planning, requirements analysis, design, coding, and testing before a working product is demonstrated to the client.

No, Unified process and the UML is not the same thing. Unified process: The Unified process is a type of framework, which is used for UML in software engineering. It is a popular iterative and incremental software development process which should be customized for specific organization or project.

A unified process (UP) [20] is a software development process that uses the UML language to represent models of the software system to be developed. It is iterative, architecture centric, use case driven and risk confronting.

The UML and Java fit together well. The value that UML adds is enhanced by the use of a visual modeling tool that supports both forward and reverse engineering (creating code from models and creating models from code). The use of a visual modeling tool also aids traceability and cross-checking of the model components.

The key characteristics of the Unified Process are: It is an iterative and incremental development framework….Those best practices are:

• Develop Software Iteratively.
• Manage Requirements.
• Use Component-based Architectures.
• Visually Model Software.
• Verify Software Quality.
• Control Changes to Software.

It identifies practices, such as use cases, iterative development, architecture driven development, team practices and process practices, which are borrowed from RUP, CMMI and agile development.

Advantages of Rational Unified Process Emphasizes the need (and proper implementation of) accurate documentation. Diffuses potential integration headaches by forcing integration to occur throughout development, specifically within the construction phase where all other coding and development is taking place.

UML (Unified Modeling Language) is a modeling language used by software developers. UML can be used for modeling a system independent of a platform language. UML is a graphical language for visualizing, specifying, constructing, and documenting information about software-intensive systems.

UML stands for Unified Modeling Language. It’s a rich language to model software solutions, application structures, system behavior and business processes. You can draw UML diagrams online using our software, or check out some UML diagram examples at our diagramming community.

Goals of UML

• Be independent of particular programming languages and development processes.
• Provide a formal basis for understanding the modeling language.
• Encourage the growth of the OO tools market.
• Support higher-level development concepts such as collaborations, frameworks, patterns and components.
• Integrate best practices.

UML is not a programming language but there are tools that can be used to generate code in various languages using UML diagrams. UML has a direct relation with object-oriented analysis and design.

The three types of modeling in UML are as follows:

• Structural modeling: – It captures the static features of a system. – It consists of the following diagrams:
• Behavioral modeling: – It describes the interaction within the system.
• Architectural modeling: – It represents the overall framework of the system.

We have designed a modeling language to model processes using high level UML- based diagrams and a low-level process language (note that UML is the abbreviation for “unified modeling language” [Fowler97]). The high level diagrams facilitate process program development.

The definition of a diagram is a graph, chart, drawing or plan that explains something by showing how the parts relate to each other. An example of diagram is a chart showing how all the departments within an organization are related.

13 different types

General diagram types are diagrams with specific shapes and methodology present with multiple specific types in multiple fields of application.

The best reason to use a diagram is to provide images of events described in the text.

In software engineering, a class diagram in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system’s classes, their attributes, operations (or methods), and the relationships among objects.

A design class diagram (DOD) illustrates the specifications for software classes and interfaces (for. example, Java interfaces) in an application.

In UML, a dependency relationship is a relationship in which one element, the client, uses or depends on another element, the supplier. As the following figure illustrates, a dependency is displayed in the diagram editor as a dashed line with an open arrow that points from the client to the supplier.

A dependency is generally shown as a dashed arrow pointing from the client (dependent) at the tail to the supplier (provider) at the arrowhead. The arrow may be labeled with an optional stereotype and an optional name.
