Event Log Extraction

Automatic

Data Base Schema Discovery :

Event Log Representation

Standarization regarding event logs

Developed XES Mapper App

Different algorithms (Apriori/Gordian)

Artifact Approach

Artifact enable communication between diff stakeholders

Artifacts are actionable

Differences between it and Entity relations (DB)

General Definitions of Artifacts

Business artifacts
provide the mechanism for information localization

An artifact is a concrete, identifiable, self-describing
chunk of information that can be used by a business
person to actually run a business.

Business artifacts constitute
concrete information chunks that the business
creates and maintains

HR: Artifact identification is as applicable to a specific
piece of a business as it is to the entire business. Thus,
if we were to consider the human resources part of
a business, its key artifact is an “employee record.”
All the other artifacts within human resources are
dedicated to support the processing of the employee
record.

Artifacts Lifecycle

Artifact processing
is a way to describe
the operations
of a business.

Java: Garbage Collection takes more time where there are more objects.

When JVM can´t allocate an object it produces OutOfMemoryError
