“Application designers need to start by thinking about what level of data integrity they need, rather than what they want, and then design their technology stack around that reality.

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

Following up on my previous blog about enabling SQL Access to CouchDB Views I thought I’d share what I think the single, biggest advantage is: The ability to connect, run of the mill, commodity BI tools to your big data system.

While the video below doesn’t show a PRPT it does show Pentaho doing Ad Hoc, drag and drop reporting on top of CouchDB with LucidDB in the middle, providing the connectivity and FULL SQL access to CouchDB. Once again, the overview:

A different vision for the value of Big Data

UPDATE: Think we’re right? Think we’re wrong? Desperate to figure out a more elegant solution to self service BI on top of CouchDB, Hive, etc? Get in touch, and please let us know!

There’s a ton of swirling about Hadoop, Big Data, and NoSQL. In short, these systems have relaxed the relational model into schema(less/minimal) to do a few things:

  • Achieve massive scalability, resiliency and redundancy on commodity hardware for data processing
  • Allow for flexible evolution and disparity in content of data, at scale, over time
  • Process semi-structured data and algorithms on these (token frequencies, social graphs, etc)

Improving healthcare in Zambia with CouchDB
+0 Vote Up -1Vote Down

A new healthcare project in Zambia is trying to integrate supervisors, clinics, and community healthcare workers (CHW) into a system that can improve patient service and provide more data about the effectiveness of care. Because of the technical challenges in an extreme rural setting, unique solutions are required. According to Cory Zue, chief technology officer of Dimagi, CouchDB went a long way toward keeping a consistent set of records under extreme circumstances. The full story will be laid out in Zue's talk at the upcoming MySQL conference, but here's a sneak peak.

I just received a confirmation that my presentation proposal for the MySQL user conference 2011 was accepted! The title for my proposal is MQL-to-SQL: a JSON-based Query Language for RDBMS Access from AJAX Applications, and it covers pretty much everything implied by the title.

As always, the Hyatt Regency Hotel in Santa Clara, California serves as the venue. The conference will be held from April 11-14. Except for the venue and period, I think this year's conference will bear few similarities to previous editions. Let me try and explain.

O’Reilly’s 2011 edition of the MySQL conference has an expanded agenda, with good representation from Postgres, CouchDB, MongoDB, and others. Take a look at the full schedule listing, which is being filled out as talks are approved and the speakers verify that they’ll give the session.

I am certainly looking forward to this year’s event. A tremendous amount of progress has landed in GA versions of open-source databases this year. To name just a couple, there’s a new version of Postgres (9.0) with built-in replication and many more improvements; there’s MySQL 5.5 GA; there’s the HandlerSocket NoSQL interface to MySQL; Drizzle has a beta release; and the list goes on.

Moving from MySQL to CouchDB: Part 1

I’ve started a little series on how to migrate your MySQL applications and databases over to CouchDB. Most of the process is about how you think about your data, not about the database itself, the application, or the interface to the database storage. There are some use cases for data storage that lend themselves to the CouchDB document model that provides some advantages over the table-based structure in MySQL. The first part of the series is Moving from MySQL to CouchDB: Part 1.

How Real is the Data Deluge?
+1 Vote Up -1Vote Down

It seems obvious that given the decreasing cost of storage and computation, there's going to be a significant increase in the volume of data that organizations accumulate over the next 10 years.  But the type of data being accumulated may be different from the areas where traditional DBMSs dominated.  It's not just about transactions; it's search patterns, on-line behavior, click-thru data, events fired off by smartphones, messages over Twitter & Facebook, log data of various kinds.

If an organization can figure out a better way identify prospects, or deliver more targeted ads, or optimize pricing decisions by analyzing terrabytes of data, they'd be crazy not to. Over the long term, companies

Do We Need a New Programming Language for Big Data?

I'm the boards of two companies (Pentaho, Revolution Analytics) that are starting to see a lot of customer traction around Big Data. More and more companies in media, pharma, retail and finance are doing advanced analysis, reporting, graphing, etc with massive data sets. It made me wonder what other areas of the technology stack might evolve with the trend towards Big Data.  Obviously, there's new middleware layers like Hadoop and Map Reduce, and we're also seeing the emergence of

A gentle introduction to CouchDB for relational practitioners
+3 Vote Up -0Vote Down

CouchDB is a document-oriented database written in Erlang that addresses a particular “sweet spot” in data storage and retrieval needs. This blog post is an introduction to CouchDB for those of us who have a relational database background.

A CouchDB database doesn’t have tables. It has a collection of documents, stored in a B+Tree. A document is a collection of attributes and values. Values can be atomic, or complex nested structures such as arrays and sub-documents. When you add a document to a database, CouchDB stores it in the B+Tree, indexed by two attributes with special meaning: _id and _rev.

CouchDB lets you store related data together even if it isn’t all the same type of data; you can store documents representing blog posts, users, and comments — all in the same database. This is not as

Persistence Smoothie: Blending NoSQL and SQL – see user feedback and comments at http://joind.in/talk/view/1332.

Michael Bleigh from Intridea, high-end Ruby and Ruby on Rails consultants, build apps from start to finish, making it scalable. He’s written a lot of stuff, available at http://github.com/intridea. @mbleigh on twitter

NoSQL is a new way to think about persistence. Most NoSQL systems are not ACID compliant (Atomicity, Consistency, Isolation, Durability).

Generally, most NoSQL systems have:

  • Denormalization
  • Eventual Consistency
  • Schema-Free
  • Horizontal Scale

NoSQL tries to scale (more) simply, it is starting to go

On SQL vs No-SQL
+1 Vote Up -0Vote Down

The No-SQL tag really lumps together a lot of concepts that are in fact as distinct from eachother as they are from SQL/RDBMS.

An object store is not at all similar to Cassandra and Hypertable, which is not at all like an column store. And when looking at BigTable derivatives, it’s quite important to realise that Google actually does joins in middle layers or apps, so while BigTable does not have joins, the apps essentially do use them – I’ve heard it professed that denormalising everything might be a fab idea, but I don’t quite believe in that for all cases, just like I don’t believe in ditching the structured form of RDBMS being the solution.

SQL/RDBMS has had a few decades of dominance now, and has thus become the great “general purpose” tool. With the ascent of all the other tools, it’s definitely worthwhile to look at them, but also realise that
