What part of NoSQL don't you understand?
+1 Vote Up -0Vote Down

In the word "NoSQL", the letters "No" are an acronym so the meaning is "Not Only SQL" rather than "No SQL". True or false?

Historically, it's false

The first NoSQL product was a classic DBMS which didn't happen to use SQL for a query language, featured in Linux Journal in 1999. Its current web page has a traffic-sign symbol of the word SQL with a bar through it, and a title "NoSQL: a non-SQL RDBMS".

MySQLNoSQLCloud 2014 – Edition #3
+0 Vote Up -0Vote Down

I’ve enjoyed visiting Buenos Aires once a year for the MySQLNoSQLCloud event, put together by the awesome people at Binlogic (in particular, their proprietor Santiago Lertora). It’s happening again in 2014, which by my count is the third edition, and there’s a twist: Buenos Aires on 13 & 14 November, and Cordoba on 17 November. It’s never been held in Cordoba before (like an annex event), so I think this could be extremely exciting.

If you’re looking to speak, send Santiago a note at …

+0 Vote Up -0Vote Down

Well, currently I am into the third week of mongodb node course "M101JS: MongoDB for Node.js Developers" and I am pretty enjoying it.

Lots of personal learning into node and mongodb.

The third week subject of "Patterns, Case Studies & Tradeoffs" is really interesting.

Here is a list of topics, I learned about:
- Mongodb rich documents concept.
- Mongodb schema use cases.
- Mongodb one:one, one:many, many:many use cases.
- How to select schema based on the usage like whether you want max performance
  or it may be a tradeoff.

Employee +1 Vote Up -0Vote Down


If you’re going to be near Edinburgh this week then consider registering for OUG Scotland. I’ll be presenting on how to acheive the benefits of NoSQL (scalability, HA, ease of use. simple APIs) while at the same time still benefiting from the RDBMS features people have grown to rely on (ACID transactions, rich schemas, flexible access patterns) – the presentation will be at 11:25 on Wednesday as part of the developers’ track.

Hint for those that can’t make it – MySQL Cluster is the key
