The Data Distribution Service (DDS) for real-time systems is an Object Management Group (OMG) machine-to-machine (sometimes called middleware or connectivity framework) standard that aims to enable dependable, high-performance, interoperable, real-time, scalable data exchanges using a publish–subscribe pattern.
Middleware services provide a more functional set of application programming interfaces to allow an application to: Locate transparently across the network, thus providing interaction with another service or application; Filter data to make them friendly usable or public via anonymization process for privacy protection (for example)
A distributed transaction operates within a distributed environment, typically involving multiple nodes across a network depending on the location of the data.A key aspect of distributed transactions is atomicity, which ensures that the transaction is completed in its entirety or not executed at all.

Message-oriented middleware is in contrast to streaming-oriented middleware where data is communicated as a sequence of bytes with no explicit message boundaries. Note that streaming protocols are almost always built above protocols using discrete messages such as frames , datagrams , packets , cells , et al.

A distributed ledger (also called a shared ledger or distributed ledger technology or DLT) is a system whereby replicated, shared, and synchronized digital data is geographically spread (distributed) across many sites, countries, or institutions. [1]
