-In a TM, processes of an application communicate using lightweight,​ in-memory transactions. Basically, a process that wants to access a shared data structure executes some operations on this structure inside a transaction. When the transaction commits, all these operations appear as if they took place instantaneously,​ at some single, unique point in time. When the transaction aborts, however, all the operations are roll-backed and their effects are never visible to other transactions. The TM paradigm is argued to be as easy to use as coarse-grained locking, and nearly as efficient on multi-core systems as hand-crafted,​ fine-grained locking.+In a TM, processes of an application ​can communicate using lightweight,​ in-memory transactions.
