This article is the second in a series on data fabric design and
introduces the transactional data service design pattern.
The previous article in this series introduced
data fabrics, which are collections of off-the-shelf DBMS servers
that applications can connect to like a single server. They
are implemented from data fabric design patterns, which are
reusable arrangements of DBMS servers, replication, and
connectivity. With this article we begin to look at
individual design patterns in detail.
