# Transaction and Optimistic Concurrency Control
In this chapter, you will implement all interfaces of `Transaction`. Your implementation will maintain a private workspace for modifications inside a transaction, and commit them in batch, so that all modifications within the transaction will only be visible to the transaction itself until commit. We only check for conflicts (i.e., serializable conflicts) when commit, and this is optimistic concurrency control.
