Short Notes : Gateways in Process Modelling, BPMN

بِسْمِ اللّهِ الرَّحْمَنِ الرَّحِيْمِ
اللهم صل على محمد وآل محمد
السَّلاَمُ عَلَيْكُمْ وَرَحْمَةُ اللهِ وَبَرَكَاتُه



Gateways in Process Modelling, BPMN

What is a parallel gateway?

Divergence element 
- A parallel gateway used as divergence element indicates a point when activities (flow paths) must be carried out at the same time and in any order.
- represent by diamond shape with plus sign

Convergence element
- A parallel gateway used as an element of convergence allows you to synchronize (combine) parallel flows into a single path.


What is a data-based exclusive gateway?

Divergence element
- indicates that only one route can be taken from the various available.
- the decision will be taken after evaluating a business condition.
- represented by diamond.

Convergence element
- A data-based exclusive gateway used as convergence element enables joining routes into a single one.

What is an event based exclusive gateway?

Divergence element
- A point in the process where only one of many branches of the process can be selected.
- The decision is based on two or more events that might occur, rather than on a data condition (as in a data-based exclusive gateway).

What is an inclusive gateway?

Divergence element
- used when a point in a process enables one or more available paths (data-based).

Convergence element
- a converging inclusive gateway synchronizes the paths activated by the diverging inclusive gateway.

What is a complex gateway?

As an element of convergence
- is used to continue the next point in the process when a business condition is met

As an element of divergence
- is used to control complex decision points


اللهم صل على محمد وآل محمد
(Allahumma salli 'ala Muhammad wa ali Muhammad)
سُبْحَانَ اللّهِ وَ بِحَمْدِهِ ، سُبْحَانَ اللّهِ الْعَظِيمِ
(SubhanAllahi wa biHamdihi, SubhanAllahil adzim)
سبحانك اللهم وبحمدك أشهد ان لا إله إلا أنت أستغفرك وآتوب إليك
(Subhanakallahumma wabihamdika asyhadu allaailaaha illa anta astaghfiruka wa atuubu ilaika)
