Q

What is business process modelling notation (BPMN)

A

BPMN provides businesses with the apability of defining and understanding their internal and external business procedures through a business process diagram, which will give organizations the ability to communicate these procedures in a standard manner

Why process model

A

Design: models make implicit choices explicit, improve communication between actors and lets you test alternatives before the process is impmented

Q

Events (process modeling)

A

Something that “happens” during the course of a business process. These events affect the flow of the process and usually have a trigger or a result. They can start, interrupt or end the flow

Q

Activities (process modeling)

A

An activity is work that is performed within a business process. An activity can be atomic or non-atomic (compound). The types of activities that are a part of a process odel are: process, subprocess and task

Q

Gateways (process modeling)

A

Modelling elements that are used to control how sequence flows interact as they converge and diverge within a process. If the flow does not need to be controlled then a gateway is not needed

20
Q

Pool (process modelling)

A

A swimlane and a graphical container for partitioning a set of activities from other pool usually in the context of B2B situations

21
Q

Lane

A

A sub-partition within a pool and will extend the entire length of the pool, either vertically or horizontally

22
Q

Data objects (process modelling)

A

Are not flow objects (i.e. connected through sequence flow), but they do provide information about how documents, data and other objects are used and updated within a process

23
Q

Tekst annotations (process modelling)

A

Are a mechanism for a modeler to provide additional information for the reader of a BPMN diagram

24
Q

Groups (process modeling)

A

Provide a mechanism to visually organize activities

25
Q

what is information(data modelling)

A

Data structured for a specific purpose

26
Q

Data model (data modelling)

A

A data model means to capture such a structure by
-Clustering data items that belong together (object/class)
-Establishing relationships between those objects
