UML Diagrams

Its Unified Modeling Language used to prepare blue prints of software

What is UML Diagrams??????

They use various notations to specify the syntax of the construct.UML notations specify how to depict the user or the classes and interface of the system.

What is UML????????

State machine describes the different states of a component in its life cycle. The notations are described in the following diagram.

State Machine Diagram

The various constituents of state Machine diagram are: 1. State Machines 2. Transitions 3. Events Advance feature of state machine are Entry and Exit actions. Activities. Internal transition. Substate Deferred events

State Machine Diagram

Identify the collaboration for a system, class or use case. Identify the start and end states for each object. Identify the stable states of each object. Identify the events that cause a transition in the state of an object. Associate actions to each transition and state. Use the sequential and concurrent states to simplify the state diagrams.

Guidelines for creating state machine diag.

Deployment diagrams are used to describe the static deployment view of a system. Deployment diagrams consist of nodes and their relationships. Purpose: The purpose of deployment diagrams can be described as: 1. Visualize hardware topology of a system.

2. Describe the hardware components used to deploy software components.

3. Describe runtime processing nodes.

Consider the Deployment Diagram of an order management system on the next slide.

Deployment Diagram

Deployment diagrams are mainly used by system engineers. Usage of deployment diagrams can be described as: To model the hardware topology of a system. To model embedded system. To model hardware details for a client/server system. To model hardware details of a distributed application. Forward and reverse engineering.

Use of deployment diagrams

Packages diagrams are used to group the related constituents of a software system. Advantages of using packages to model the constituents of a software system are: Enables visualizing the functional groups and the relationships among them. Facilitates easy management of large software systems.

Package Diagrams

Symbols used to set the visibility of constituents in packages are: + : Indicates that the constituents is public , accessible to the constituents of other packages. # : Indicates that the constituents is protected,

accessible to the constituents that inherit it. - : Indicates that the constituents is private ,

accessible to the constituents outside the package.

Symbols in packages

Component diagrams are used to model the various components required for a system execute.

Purpose: 1. Visualize the components of a system. 2. Construct executables by using forward and reverse engineering. 3. Describe the organization and relationships of the

components. Consider the Component Diagram of an order management system on the next slide.

Component Diagram

Component diagrams are used to visualize the static implementation view of a system. Usage of component diagrams can be described as: Model the components of a system. Model database schema. Model executables of an application. Model system's source code.

Uses of Component Diagram

It is a specific type of Interaction Diagram.

They are used to represent the changes in state and value of one or more objects

over a period of time.

Timing Diagram

A value lifeline is used to represent the changes in the value of objects over a period of time.

Concise Notation

A state lifeline is used to represent the changes in state of objects over a period of time.

Robust Notation
