Storage of business process events

Business process events are collected for the purpose of logging process operations and performance analysis. During the simulation, a large amount of "raw" information is collected, for its storage supported modern browsers NoSQL IndexedDB. The advantages of this approach are:

Security - user data is stored locally
Performance - asynchronous access to the storage does not slow down the calculations
Volume - is almost endless storage space.

When starting the service, the following databases are created:

logs storage of business process logs

View and manage the contents of the service repository are available on the Application/Storage/IndexedDB tab of DevTools. Task event object repository

Simulation Log Storage Structure

Task events (Task object storage)

Task events are stored to enable task-based analysis of the effectiveness of the business process (in terms of the task).

Key	Name	Description
kind	Kind of event	The digital value of the event type directory app.options.types.eventType: taskNew - task created taskComplete - task completed in Function taskDelivered - task delivered to Object taskAssigned - task is assigned to Executor taskWaitQueue - task wait in Queue taskFinished - task is finished in Process taskCostSpent - task spent cost of Executor taskOperation - taskSupported - task spent Resource
kindName	Name of kind of event	String value of the event type app.options.types.eventType
source	Event source	ID of the business process model object where the task event was registered.
sourceName	Name of event source	The name of the object - the source of the event at the time of the event
task	Task ID	Unique within the simulation session task ID
time	Time of event	Process time of event registration in Unix Timestamp format
cost	Cost	The amount of cash costs for the task execution by the performer. Filled if applicable.
duration	Duration	The duration of the event. Filled if applicable.

Example of a task event object in JSON format


{
     kind: 2
     kindName: "taskDelivered"
     source: "82493adc-f669-4d0e-a100-ca34b6ed"
     sourceName: "Function №1"
     task: 2
     time: 1552889013000
}

The task event repository is completely cleared before the start of each new session of the business process simulation.
