Distributed Transactions Coordination

A Data Virtualization and Data Federation Platform could be seen in many cases as a way to query heterogeneous data pieces. But Denodo does not only provide query features for federated data; it also allows distributed transactions writing back to the data sources using SQL Insert / Update / Delete statements, enabling Denodo Data Services Platform to act as a complete SOA Data Hub in all kinds of operations.

Denodo allows defining transactions involving several of these operations. In these situations, it is crucial to guarantee that distributed transactions fulfill ACID properties: atomicity, consistency, isolation and durability. Denodo implements the "de facto" standard Two-Phase-Commit protocol to coordinate distributed transactions among different data sources providing the aforementioned properties.
