The Unified Modeling Language ( Uml )

This step creates model of the software system based on the stockholder’s requirements, then requirements are analyzed again to produce a fine model of the software

Options A, B, and C. This chapter has three options depending upon your previous experience with a manual version systems project called the Systems Understanding Aid, written by the same authors as this computerized project. Option A is for students who have not used the Systems Understanding Aid before. Option B is for students who have completed the Systems Understanding Aid before using Transactions List A (Document No. 1). Option C is for students who have completed the Systems Understanding Aid before using Transactions List B (Document No. 1).

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.

The UML Collaboration diagram bellow was created in order to model how the objects involved in the Minecraft scenario interact with each other and their job is to instantiate the class of the system. The objects are connected by links; the links represent an instance of the association between the classes. The messages are exchanged between the objects to specify what the steps of the interaction are.

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.

The wolf-moose relationship will first be modeled using UML. The purpose and requirements of the conceptual model will be captured using UML via use case diagrams. Furthermore, a class diagram will be used to document the system components, and a state diagram will be used to capture the possible states of a wolf and moose. The state diagram may also be used as a building block for possible Markov Chain and Bayesian Net models. Sequence and Activity diagrams will also be generated to model the dynamic behavior of the predator-prey relationship. This model will be particularly useful for building a dynamic model.

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.

* Imagine that you have been working on a project to design and build a given system. You have completed the elicitation and evaluation phases and now you need to specify and document the system-to-be. Suppose you have decided to use diagrammatic notations for the specification and documentation. Your options are to use context diagrams or frame diagrams. Evaluate each type of diagram and select the one you feel is the best fit. Provide a rationale.

The above figure shows the UML diagram; our project contains six major classes namely Node, FaultInjector, PingMap, MonitorAgent, LearningAgent and MachineLearningBlock. The MachineLearningBlock class is sub-class to the LearningAgent class. This handles all the functions from injecting faults, requesting for the TCP statistics, and analysis by the machine learning block.

Following document explains what are data models and the importance of data model. Building a good data model helps organizations in software development, data base design and product maintenance. The document explains the theory, even if it looks like the organizations are spending substantial amount of resources on developing data models, but still it helps organization, keeping the costs low and build a better product.

For creating models we need to have certain process other than the use of UML itself. We can use any tool depending upon the application. Notation guide is available for any references.
