# Transactions (beta)
-Above and beyond the row-level transactional semantics of HBase, Phoenix adds
cross row and cross table transaction support with full
[ACID](https://en.wikipedia.org/wiki/ACID) semantics by integrating with a
transaction library named [Tephra](http://tephra.io/). Tephra provides snapshot
isolation of concurrent transactions by implementing multi-versioned
concurrency control.
