Design rules management system.
sample rules:
A = B + C AND B * C > 1000
B * C > 1000
A and B = True

User can Create / Modify / View rules.
Actions and events are associated with rules. User can edit those as well.

Events will trigger rules

rules will be evaluated based on the condition. and actions will be called for those conditions.

Where we will store the Rule and Actions
Which DB is suitable to store these Rules.
Looking for right approach for this above question.
