Business Process Modelling Notation

Originally developed by the Business Process Management Initiative(BPMI)

Business Process Modelling Notation

Intended to be used by stakeholders who design, manage, and realize business process (BP)

Business Process Modeling Notation

It has an easy-to-use flowchart-like notation that is independent of any particular implementation environment

Business Process Modeling Notation

This helps with communication leading to Extensible Markup Language

Event

A trigger starts, modifies, or complete a process. Event types include message, timer, error, compensation, signal, cancel, escalation, link, etc.

Activity

A particular task performed by a person or system.

Activity

It can include sub-processes, loops, multiple loops, and compensations

Gateway

A decision that can adjust the path based on conditions or events. A gateway can be exclusive or inclusive, parallel, complex, or based on data or event

Connecting Objects

• Sequence flow

• Message flow

• Association

Sequence flow

This show the order of activities to be performedMe

Message Flow

This depicts messages that flow across pools, or organization boundaries such as departments.

Association

This associates an artifact text to an event, activity, or a gateway.

Swinlanes

• Pool

• Lane

Pool

It represents major participants in a process. a different pool

Lane

It is a sub-part of a pool. it shows the activities and flow for a certain role or participant, defining the accountability within the process.

Artifacts

• Data object

• Group

  • Annotation

Data Oject

This shows the necessary data for an activity.

Group

This shows a logical grouping of activities, but does not change the diagram flow

Annotation

This provides further explanation to a part of the diagram

Sub-Models of BPMN

• Private BP

• Abstract BP

• Collaborative BP

Unified Modeling Language (UML)

This was created to establish a common, semantic, and syntactical visual modeling language for the architecture, design, and implementation of complex software systems both structurally and behaviorally

Unified Modeling Language (UML)

the most important industry standard language for specifying, visualizing, constructing, and documenting software systems.

Unified Modeling Language (UML)

Emerged from the combination of three (3) existing practices namely: Booch Method, Object-Modeling Technique (OMT), and Objectory

Modeling Concepts Specified by UML

• Functional

• Object

  • Dynamic

Functional

This concept involves use case diagrams, which describe system functionality from the point of view of a user

Object

This concept involves class diagrams, which describes the structure of a system in terms of objects, attributes, associations, and operations.

Dynamic

This concept involves interaction diagrams, state machine diagrams, and activity diagrams, which used to describe internal behavior of the system.

Types of UML Diagrams

• Structural UML Diagrams

• Behavioral UML Diagrams

Class Diagram

it describes the static structure of a system.

Package Diagrams

It is a subnet of a class diagram used to organize elements of a system into related groups.

Object Diagram

It describes the static structure of a system at a particular time, and can be used to test class diagrams for accuracy.

Component Diagram

This describes the organization of physical software components, including source codes, run-time code, and executables.

Composite Structure Diagram

This diagram shows the internal part of a class.

Deployment Diagram

This depicts the physical resources in a system, including nodes, components, and connections.

Structural UML Diagrams

• Class diagram

• Package diagram

• Object diagram

• Component diagram

• Composite diagram

• Deployment diagram

Activity Diagram

This illustrates the dynamic nature of a system by modeling the flow of control from activity to activity.

Communication Diagram

This describes the interaction among classes in terms of an exchange of the message over time.

Use-Case Diagram

This models the functionalities of a system using actors and use cases, and can be considered as a simplified version of a collaboration diagram introduced in UML 2.0.

State Machine Diagram

This describes the dynamic behavior of a system in response to external stimuli.

Sequence Diagram

It models the interactions between objects in sequence.

Interaction Overview Diagram

It is a combination of an activity and a sequence diagram, which models a more complex interaction

Timing Diagram

It is an Interaction UML Diagram that focuses on processes that take place during a specific period of time, wherein time is shown to increase from left to right.

Behavioral UML Diagrams

• Activity diagram

• Communication diagram

• Use case diagram

• State machine diagram

• Sequence diagram

• Interaction overview diagram

• Timing diagram
