[Fiware-tech-help] CEP Proton- Help with different entities and different rules

[Tali Yatzkar-Haham]

Dear Ahmed,

Yes, you can use the same definition file for different patients, assuming 
you have a way to identify which patients need which rules.

There are several ways to do it.
One simple option would be to add to the current condition a condition 
over the patient identity. 

Example: 
Rule1: e1.HeartRate >100 && e1.patientName="A" ---> CEP --> Produce event 
Rule2: e1.BloodPressure >120 && e1.patientName="B" ---> CEP --> Produce 
event

Or:
Rule1: e1.HeartRate >100 && e1.group="A" ---> CEP --> Produce event 
Rule2: e1.BloodPressure >120 && e1.group="B" ---> CEP --> Produce event

Hope that helped,
Best regards,
Tali

Dear Tali,

We are working with a medical project involves the usage of CEP to check 
patient data against certain rules and produce an event when this rules 
are satisfied.

The question is for different patients , Do we need to have multiple rule 
files (one definition file for each patient) and upload them and activate 
them each time we need to check one patient data or there are better 
solution that would allow us to check different patients for different 
rules in the same definition file ?

Example: 
Patient A, Heart rate >100 ---> CEP --> Produce event
Patient B, Blood pressure >120 ---> CEP --> Produce event

Best Regards,

Ahmed Sadek
