Data Fabric Design Patterns: Fabric Connector

This article is the third in a series on data fabric design and introduces the fabric connector service design pattern.  The previous article in this series introduced the transactional data service design pattern, which defines individual data stores and is the building block for data fabrics based on SQL databases.  The fabric connector builds on transactional data services and is another basic building block of fabric architecture.

Description and Responsibilities
Fabric connectors make a collection of DBMS servers look like a single server.  The fabric connector presents what appears to be a data service API to applications.  It routes each request to an appropriate physical …

Data Fabric Design Patterns: Transactional Data Service

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.

Description and Responsibilities
The transactional data service is a basic building block of data fabric architectures.  A transactional data service is a DBMS server that processes transactions submitted by applications and stores data safely.  Transactional data services have the …

Introducing Data Fabric Design for Commodity SQL Databases

Introducing Data Fabric Design for Commodity SQL Databases

Data management is undergoing a revolution.  Many businesses now depend on data sets that vastly exceed the capacity of DBMS servers.  Applications operate 24x7 in complex cloud environments using small and relatively unreliable VMs.  Managers need to act on new information from those systems in real-time. Users want constant and speedy access to their data in locations across the planet.

It is tempting to think popular SQL databases like MySQL and PostgreSQL have no place in this new world.  They manage small quantities of data, lack scalability features like parallel query, and have weak availability models.  One reaction is to discard them and adopt alternatives like Cassandra or MongoDB.  Yet open source SQL databases have tremendous strengths:  simplicity, robust transaction support, lightning fast operation, flexible APIs, and broad communities of users familiar with their operation.  The …

Our 2013 Database survey is now live

451 Research’s 2013 Database survey is now live at http://bit.ly/451db13 investigating the current use of database technologies, including MySQL, NoSQL and NewSQL, as well as traditional relation and non-relational databases.

The aim of this survey is to identify trends in database usage, as well as changing attitudes to MySQL following its acquisition by Oracle, and the competitive dynamic between MySQL and other databases, including NoSQL and NewSQL technologies.

There are just 15 questions to answer, spread over five pages, and the entire survey should take less than ten minutes to complete.

All individual responses are of course confidential. The results will be published as part of a major research report due during Q2.

The MySQL Community: Beleaguered or Better than Ever?

The  MariaDB Foundation announcement spawned some interesting commentary about the state of open source databases.  One recent headline cited the "beleaguered MySQL community." Beleaguered is a delightful adjective.  The OED tells us that it means beset, invested, or besieged.  Much as I like the word, I do not think it is an accurate or useful description of the MySQL community.  This article and others like it miss the point of what is happening to MySQL and its users.
