Application Of Uml Using Uml Diagrams Used At Each Stage Of The Software Development Process

A profile allows UML to be extended for use with a particular programming platform or to model systems intended for use in a particular domain. A profile extends the UML to allow user-defined stereotypes, meta-attributes, and constraints.

In the object-oriented modelling class diagrams are very important. In data modelling techniques class diagrams are used. These class diagrams are represented by using the box symbol.

In order to solve the programming problem that we are facing, we need to define the flow of the program and the actions that the program must take. Attempting to write a successful program without considering how to solve the problem and how the program must be created makes the task very difficult for the programmer. This is where flowcharts or pseudocode will help us build a conceptual model of how a program will work before we get into the complexity of the programming language.

Team Mates as you know that we have chosen the Requirements in System Development Life Cycle, so have came across the following stages in the Requirements in my research which will be posted below specifically under their requirements.

*Uml diagram that show the logical view include these class diagrams and class diagrams by the way are by far the most common kind of uml diagrams. you’ll be seeing and working with these a lot also state diagrams, object object diagrams, sequence diagrams, and communication diagrams. Each type of diagram has its own set of function statement definition.

what make the system, there are several different styles which can be used to create a Program or

In current era use of computers and machines are become vital in daily life. To operate these machines, we need to give them instruction of doing some work in specific format which is called software. So, when a problem arises or identified and one want a solution by using machines, need of new software arise. And thus, a software development life cycle starts. To make this life cycle more efficient and accurate, different SDLC model and software development modeling techniques exist. Here in this research paper we will discuss software modeling techniques. The term “model” is derived from the Latin word modulus, which means pattern, measure, and rule. While a modeling language is any artificial

Context diagrams are important to software engineering as it provides overall view of the system and the interaction among entities, different elements of the system. It ensures that entities in the system belongs to the system and thus help in development and refactoring of system completely. Context diagrams should be developed and analyzed before any system is refactored. Since in context diagram we know the inputs and outputs of the system we can predict how the system works and anticipate any errors, and if any output is not got from input We can easily make out whether the system is working properly or not for particular interval or not and thus it improves safety and reliability.

Network architecture is the configuration of an interchanges system. It is a structure for the determination of a system's physical parts and their practical association and setup, its operational standards and systems, and information organizations utilized as a part of its operation. Network Architecture gives the subtle element outline of a system. It is utilized to arrange all the system layers regulated in sensible structure by portraying each one stage in subtle element. It is likewise dependent upon the complete working meanings of the conventions. The structural engineering is emphasized in a circulated processing environment and its unpredictability can’t be comprehended without a structure. Subsequently there is a need to create provisions or systems to design a diagram of a system. The first use of the expression "software architecture planning" put it particularly in the arranging period of a task. While these arrangements had connection to physical items, the term finished not. At the point when a system of associated gadgets, for example, phones and PCs, was arranged out, the outcome was a system building design schematic. The real plans were for the most part extremely fundamental; they might be all the more a rule than else other possibilities. In time, the system construction modeling schematic started to hold extra material identifying with the system. Particular physical articles were allocated positions dependent upon the

The above diagrams give us a perfect scenario of all the functions which can be easily accessed by a user to make the different diagrams.

From an analysis of the existing code generation tools for UML diagrams, we conclude that:

The Unified Modeling Language (UML), with its fourteen various diagram types, is a standard notation for the modeling of real-world objects as a first step in developing an object-oriented design method. Although a lot of semantics in the UML, we can widely describe in the more details the system that will be developed, but we cannot make sure the correctness and consistency of the designed model. Therefore, it is important to reduce the error from verifying user model in the early phase, When those errors are discovered early in the design process it is easier and more cost helpful to fix than if they were discovered at a later phase. The issue of consistency and inconsistency have appeared since its infancy of the software development. These problems are bigger still in UML software development, and are mainly reason of the presence of multiple-views (models) for the same system, and It can contain potentially contradictory system specifications. In other meaning, the UML diagrams describing a software must be consistent because inconsistencies between all diagrams in UML It will be the source of the increase defects and errors in the software systems. It is therefore important that these inconsistencies be detected in the system, analyzed and hopefully fixed before implementing it. Without consistency analysis, it would be hard to evolve the model and ensure that the collaborative effort is coherent. Although there are a lot of research and studies that focus on the
