MOT Concurrency Control Mechanism

After investing extensive research to find the best concurrency control mechanism, we concluded that SILO^[Comparison – Disk vs. MOT^]-based on OCC is the best ACID-compliant OCC algorithm for MOT. SILO provides the best foundation for MOT's challenging requirements.

NOTE: MOT is fully Atomicity, Consistency, Isolation, Durability (ACID)-compliant, as described in the MOT Introduction section.

The following topics describe MOT's concurrency control mechanism –

• MOT Local and Global Memory

• MOT SILO Enhancements

• MOT Isolation Levels

• MOT Optimistic Concurrency Control
