Component Diagram of an Insurance Policy Administration System

In Unified Modeling Language (UML), a component diagram depicts how components are wired together to form larger components or software systems.They are used to illustrate the structure of arbitrarily complex systems.


A component diagram allows verification that a system's required functionality is acceptable. These diagrams are also used as a communication tool between the developer and stakeholders of the system. Programmers and developers use the diagrams to formalize a roadmap for the implementation, allowing for better decision-making about task assignment or needed skill improvements. System administrators can use component diagrams to plan ahead, using the view of the logical software components and their relationships on the system.[1]

Diagram elements[edit]

  1. A sequence diagram shows the sequence (in time) of messages, which are exchanged among roles that implement the behavior of the system. This section of the tutorial guides you through the process of creating a sequence diagram using Rational Application Developer. Create a sequence diagram 1. From the Package Explorer view, expand the.
  2. Sequence Diagram A Sequence Diagram is used to specify a behavior with a focus on how the parts of a block interact with one another via operation calls and asynchronous signals. Sequence diagrams are commonly used as a detailed design tool to precisely specify a behavior as an input to the development stage of the lifecycle.

The component diagram extends the information given in a component notation element. One way of illustrating the provided and required interfaces by the specified component is in the form of a rectangular compartment attached to the component element.[2] Another accepted way of presenting the interfaces is to use the ball-and-socket graphic convention. A provided dependency from a component to an interface is illustrated with a solid line to the component using the interface from a 'lollipop', or ball, labelled with the name of the interface. A required usage dependency from a component to an interface is illustrated by a half-circle, or socket, labelled with the name of the interface, attached by a solid line to the component that requires this interface. Inherited interfaces may be shown with a lollipop, preceding the name label with a caret symbol. To illustrate dependencies between the two, use a solid line with a plain arrowhead joining the socket to the lollipop.[3]

A DevOps tools approach to agile software development helps developers and operations teams build, test, deploy and monitor applications with speed, quality and control. Successful DevOps software implementations generally rely on an integrated set of solutions, or a toolchain, to remove manual steps, reduce errors, increase team agility and scale beyond small, isolated tea.

What is a SysML Block Definition diagram?


Block: A Block (notation: rectangle with keyword = «block») represents a system component, a modular structural unit that encapsulates its contents (Properties, Behaviors, Constraints) and supports first-class (i.e., can be drawn and directly manipulated in the model repository) Interfaces. Behaviors encapsulated by Blocks include: Operations, Signals, and State Machines. The unique interaction points for attaching and connecting ('wiring') Block Interfaces are called Ports.

Class diagram
  • Blocks can specify software, hardware, mechanical, and wetware (persons, organizations, facilities) components.
  • Blocks support both Provided (implemented or realized) and Required (used) Interfaces for both information and physical flows.
  • Blocks can be recursively decomposed into Parts, where each Part must also be defined by a Block. (See Usage Notes below.)

Block Definition Diagram (bdd): A Block Definition Diagram is a static structural diagram that shows system components, their contents (Properties, Behaviors, Constraints), Interfaces, and relationships.

  • Blocks can be recursively decomposed ('nested') into Parts by alternating between Block Definition Diagram (BDD) definitions and Internal Block Diagram (IBD) usages (See Usage Notes below.)
  • Behaviors can either be encapsulated by Blocks (e.g., Operations, Signals, and State Machines) or Allocated (via «allocate» Dependency) to Blocks (e.g., Activities/Actions) directly or indirectly (via Interfaces).
  • Blocks can be mathematically constrained via Constraint Blocks to produce mathematically simulatable Parametric diagrams.

The purpose of Block Definition Diagrams is to specify system static structures that be used for Control Objects, Data Objects, and Interface Objects. When properly applied (See Usage Notes below) Block diagrams are recursively scalable and mathematically (parametrically) simulatable (See Executable Semantics below.)
