The term global transaction is defined as a unit of work which takes place in an environment in which the process of distribution of transactions takes place. A global transaction is a transaction which requires the efforts of more than one manager of resources. A global transaction also involves co-ordinating several types of services. These services may be located in different programs on the server. It is also known as a distributed transaction.
On the other hand, the term local transaction is defined as a type of transaction in which each of the managers of resources who is involved separately co-ordinates only its own changes. They do not have a sync point co-ordinator, such as an RRS, to co-ordinate them. It involves one service within a single server program and accesses only a single database.
