The system's architecture permits a process automation application in one domain to interact with a process automation application in a second domain. The application interaction protocol together with the transaction definition data structure permit the process automation application to distribute constituent...
SAGAs are mechanisms to maintain data consistency in a microservice architecture without having to use distributed transactions. You define a SAGA for each system command that needs to update data in multiple services. A SAGA is a sequence of local transactions. Each local transaction updates data ...

Connectivity:A related challenge is maintaining a communication network between the nodes. There are two approaches to do this. On one extreme, we have theclient-server architecturewhere all nodes communicate only with the centralized server. The server has the complete picture of the network and ...
A distributed transaction is a set of operations on data that is performed across two or more data repositories (especially databases).

A distributed transaction spans two or more databases. As the transaction manager, DTC coordinates the transaction between SQL Server instances, and other data sources. Each instance of the SQL Server database engine can operate as a resource manager. When an availability gr...
