…it gets interesting. Read committed is the default isolation level in PostgreSQL and Oracle, and is one step up from read uncommitted. It is the most "common sense" level: Bob will not see any changes made by Tom until Tom commits them.
MySQL defaults to *read repeatable*. In this level, Bob will not see any _updates_ Tom commits, but will see any _inserts_. Say in Bob's first select he sees one book titled "The Odessey". Tom then fixes the spelling …

…RDBMS implementations ( MySQL, PostgreSQL, Oracle, etc) have been the one-size-fits-all solution for data persistence and retrieval for decades. The rise of the web and the LAMP stack cemented the role of the relational database. But in 2010 we see a variety of application needs which are not satisfied by MySQL and friends. New problems demand new tools. High availability, horizontal scaling, replication, schemaless design, and map/reduce capability are some of the areas being explored …

…PDC and Tech: Ed, and Sun's JavaOne (now Oracle's OpenWorld) are well-established and heavily-attended. But huge international conferences need huge budgets and big name sponsors, which forces them to be more like trade shows than developer events. It should be noted that there's only one Ruby conference with a "show floor", and that's RailsConf.
Also, Ruby has never had a large corporation to champion it. No Sun, Microsoft, or Apple to bankroll …

Will VoltDB kill off the new NoSQL upstarts? Will VoltDB cause a mass extinction of ancient databases? Probably no and no to both questions, but it's a product with a definite point-of-view and is worth a look as the transaction component in your system. But will it be right for you? Let's see...

Forrester released their new wave report: T he Forrester Wave™: Elastic Caching Platforms, Q2 2010 where they listed GigaSpaces, IBM, Oracle, and Terracotta as leading vendors in the field. In this post I'd like to take some time to explain what some of these terms mean, and why they're important to you. I'll start with a definition of Elastic Data Grid ( Elastic Caching), how it is different then other caching and NoSQL alternatives, and more importantly …
Oracle XE is even more restrictive than SQL Server Express and seriously insecure, having not been updated for a long time despite the presence of major security vulnerabilities. Unlike Oracle XE, DB2 Express-C uses the same core code as its commercial editions and is always kept up-to-date.
In case you are wondering, there's no catch. We generate our revenue from affordable, but entirely optional, dedicated 24/7 technical support (a popular business model in the open source community). …
…big examples, IBM obviously interacts with open source and contributes to it a lot. Oracle just acquired Sun, so there's a ton of open source in their portfolio. Even Microsoft now contributes to the Linux kernel and has a whole bunch of little projects they've released as open source.
If your company gets really huge, it will almost certainly interact with projects and contribute code, but more along the lines of what you're alluding to, your developers are just going to …
