Database State Isolation

Database State Isolation ensures that the effects of one transaction are not visible to other concurrent transactions until the first one is successfully committed. This is a critical property for financial systems where intermediate states ⎊ such as a partially filled order ⎊ could be exploited if visible.

By isolating state changes, the system prevents users from making decisions based on incomplete or inaccurate data. This ensures that every trade is executed against a consistent and verified state.

It is a fundamental concept in maintaining the security of derivative order books.
