You're welcome!

The data log is typically extracted using ETL tools. ETL stands for 'Extract, Transform and Load'. A popular ETL language/tool is SQL. You can read up on how ETL works online. With regards to your question on timestamp: consider putting protocols in place that allow for data anonymization during the ETL process. That way, you can still apply process mining without infringing on privacy. For more information on how to do this, check out this link: fluxicon.com/book/read/project/ , specifically the section of that article called '3. Consider Anonymization'. Let me know if that helps.

Those are sample datasets that Celonis provide users to experiment with. They are derived from/ match with some datasets commonly found in the most common ERP systems (e.g. SAP). So there are about 6 that focus on some popular processes (order to cash), but you can upload your own using the 'quick upload' button.

I suggest you check out my courses on Udemy about process mining. These are specifically made to make the complicated field of process mining understandable through easily digestible educational material

Yes I can

With the expression 'from the get go', I mean that you can use BPMN modelling to design your process BEFORE implementing an ERP system such as SAP. So that you can design processes from the start (before any data is generated). Once the designed process is implemented (for example the ERP system is operational), it will generate data that you can then use to compare with your pre-defined process model (using conformance checking). Let me know if that answers your question.

Hi sagar, I aim for a healthy balance between the theoretical aspects of process mining and the practical application of the Celonis tool. Thanks for watching!
