Transaction的四个基本属性总结来讲就是ACID


1. Atomic
Transaction must execute completely or not at all
2. Consistent
Data in database is always in a consistent state (makes sense)
Constraints (primary keys, referential integrity, etc.)
3. Isolated
Transaction executes without interference
4. Durable
Changes are not lost if the system crashes
