The Unified Modeling Language ( Uml )

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.

Logic models represent a visual way of expressing the rationale or thought behind a program. Two other forms of expression may help concurrently support the development of a logic model, or accompany the model if it is to be communicated through written materials.

This engineering standard provides a standardized collection of terminology related to systems and software engineering, as well as references to other source standards where the included terms may be actively defined.

Logical and physical models represent the key elements and processes of the software development. The logical model describes the processes, and data, in as much detail as possible, without giving regard to how the system will be implemented. Logical data models include

* Compare Entity-Relationship (ER) diagrams, Structured Analysis and Design Technique (SADT) diagrams, data flow diagrams (DFD), and Unified

Here the model depicts five use the logical view, the process view, the physical view, development view and use case view. These views of the system are concurrent and each offers its own

As design moves forward, the development teams begin to generate a tremendous amount of detailed information about the system. Modules, classes, data fields, data structures, forms, reports, methods, subroutines, and tables are all being defined in substantial detail in the design model. The key design tasks are decomposing the application into layers, clients, and servers, distributing the “pieces” across hardware platforms, and defining the physical network and protocols.

ThyssenKrupp Ag employs 17,000 employees in 80 countries that are passionate and are experts in developing solution for sustainable progress. The company manages global growth with innovations and technical progress along with using finite resources in a sustainable way. ThyssenKrupp pushes the company to evolve which helps them to meet global challenges of the future with their innovation solutions.

In the last two decades modeling notations and tools subsequently claimed to be the "silver bullets" for success in software development, however, expectations were not met. This is due in large part to another important element, development methodology, had been postponed. They are worthless if good notations and tools for application directives are not provided. So, this decade has begun with a growing interest in development methodologies. Until recently he led the development process associated with a strong emphasis on process control through a rigorous definition of roles, activities and artifacts, including modeling and detailed documentation. This "traditional" scheme to address software development has proven effective and necessary in large projects (regarding time and resources), which usually requires a high degree of ceremony in the process. However, this approach is not be the most suitable for many current projects where the system environment is changing, and where required drastically reduce development time while maintaining high quality. Given the difficulties in using traditional methods with these constraints of time and flexibility, many development teams resign

System development life cycle is a process use for the period of development system. SDLC contains four main steps those are analysis, planning, design and implementation during the analysis steps of dataflow diagram used to process the model of a system. A consistency of the context diagram to lower dataflow diagram is very important for easy process model of a system, manual consistency check from context to lower level data flow diagram using a checklist is time intense process

The “Unified Modeling Language“, in the area of software engineering is referred to a standard notation of modeling language”. For Object oriented development, UML is approved as a standard for modeling. According to software engineering, “Unified Modeling Language” is a language but not a methodology. UML is a graphical language which includes a set of charts and diagrams for depicting programming frameworks. The key aim of UML is to design and document the software or the system. The UML has evolved in the mid of 1990’s with the combination of thee competitive approaches of Object Oriented methodologies, which were formulated by Grady Booch,

The model attempts to develop students’ creativity learning which requires critical thinking and problem-solving skills. Thus, the model emphasizes the use of a hands-on and cooperative learning experience in the process of addition, subtraction, and interpreting data to improve decision-making skills. For instance, students encouraged to use real objects to practice addition and subtraction by adding to, taking from, putting together, and taking apart. Then, they will be

Option 3. Introduce one UML tool of your choice. List its important features and then show its advantages and disadvantages compared with other tools.

The main advantage of this approach to benefit from the UML standard modeling notation and the training done with software engineers to model the software with the UML notation
