If yes, can you please give me the justification This article helped to complete my engineering mini project which in turn led me to register to this prestigious site.
Taking this as an inspiration, I completed my mini project on my own i. I even posted that mini project on YouTube domain as an article in this site. I personally feel that the use case diagrams look complicated. As it is not mandatory to involve all types of users in one use case diagram, you could split the use case diagrams into two or more parts.
By the way, the component diagrams are very properly drawn and I appreciate you for that. Could you post object diagram of online mobile recharge for the benefit of all?

Component A component is a physical and replicable part that conforms to and provides the realization of a set of interfaces.
Node A physical resource that exists in run time and represents a computational resource. Interaction Set of messages exchanged among a set of objects within a particular context to accomplish a specific purpose. State machine A behavior that specifies the sequences of states an object or an interaction goes through during its lifetime in response to events, together with its responses to those events. Packages General purpose mechanism of organizing elements into groups.
Note A symbol for rendering notes and constraints attached to an element or a collection of elements. The types of UML relationships are shown in the table 2, relationships are used to connect things into well defined models UML diagrams.
Use-case diagram. A use case illustrates a unit of functionality provided by the system. The main purpose of the use-case diagram is to help development teams visualize the functional requirements of a system, including the relationship of "actors" human beings who will interact with the system to essential processes, as well as the relationships among different use cases.
Use-case diagrams generally show groups of use cases — either all use cases for the complete system, or a breakout of a particular group of use cases with related functionality e. To draw an actor indicating a system user on a use-case diagram, you draw a stick person to the left or right of your diagram and just in case you're wondering, some people draw prettier stick people than others.
The class diagram shows how the different entities people, things, and data relate to each other; in other words, it shows the static structures of the system. A class diagram can be used to display logical classes, which are typically the kinds of things the business people in an organization talk about. Class diagrams can also be used to show implementation classes, which are the things that programmers typically deal with.
The implementation class diagram won't be drawn with the same attributes, however, because it will most likely have references to things like Vectors and Hash Maps. An Object diagram focuses on some particular set of object instances and attributes, and the links between the instances. A correlated set of object diagrams provides insight into how an arbitrary view of a system is expected to evolve over time. Only those aspects of a model that are of current interest need be shown on an object diagram.
Sequence diagrams show a detailed flow for a specific use case or even just part of a specific use case. They are almost self explanatory; they show the calls between the different objects in their sequence and can show, at a detailed level, different calls to different objects. A sequence diagram is very simple to draw. Across the top of your diagram, identify the class instances objects by putting each class instance inside a box.
State-chart diagram. The state-chart diagram models the different states that a class can be in and how that class transitions from state to state. It can be argued that every class has a state, but that every class shouldn't have a state-chart diagram.
Only classes with "interesting" states — that is, classes with three or more potential states during system activity — should be modeled.
The notation set of the state-chart diagram has five basic elements: the initial starting point, which is drawn using a solid circle; a transition between states, which is drawn using a line with an open arrowhead; a state, which is drawn using a rectangle with rounded corners; a decision point, which is drawn as an open circle; and one or more termination points, which are drawn using a circle with a solid circle inside it.
Draw the states themselves anywhere on the diagram, and then simply connect them using the state transition lines. Activity diagrams show the procedural flow of control between two or more class objects while processing an activity.
Activity diagrams can be used to model higher-level business process at the business unit level, or to model low-level internal class actions. In my experience, activity diagrams are best used to model higher-level processes, such as how the company is currently doing business, or how it would like to do business.
This is because activity diagrams are "less technical" in appearance, compared to sequence diagrams, and business-minded people tend to understand them more quickly. Component diagram. A component diagram provides a physical view of the system. Its purpose is to show the dependencies that the software has on the other software components e. The diagram can be shown at a very high level, with just the large-grain components, or it can be shown at the component package level.
UI or Java's packages e. The deployment diagram shows how a system will be physically deployed in the hardware environment. Its purpose is to show where the different components of the system will physically run and how they will communicate with each other. Since the diagram models the physical runtime, a system's production staff will make considerable use of this diagram.
The notation in a deployment diagram includes the notation elements used in a component diagram, with a couple of additions, including the concept of a node. A node represents either a physical machine or a virtual machine node e.
To model a node, simply draw a three-dimensional cube with the name of the node at the top of the cube. UML does not provide the magic solution to all embedded development problems. However, it is possible to make significant steps to improve the productivity of a developer by using UML model-driven development and robust and powerful OO language.
Finally, code generation increases UML's value to the developer by reducing errors and improving productivity. Open navigation menu. Close suggestions Search Search. User Settings. Skip carousel.

UML Diagram Classification—Static, Dynamic, and Implementation A software system can be said to have two distinct characteristics: a structural, "static" part and a behavioral, "dynamic" part.
Actor The outside entity that communicates with a system, typically a person playing a role or an external device Use Case A description of set of sequence of actions that a system perform that produces an observable result of value to a particular actor.
Active class A class whose objects own a process or execution thread and therefore can initiate a control activity on their own Component A component is a physical and replicable part that conforms to and provides the realization of a set of interfaces. Relations The types of UML relationships are shown in the table 2, relationships are used to connect things into well defined models UML diagrams.
