• Some business trends in the data warehouse market

    Updated: 2010-03-19 06:48:42
    In recent conversations with various analytic DBMS vendors, a fairly consistent picture has emerged. Business is strong. Multiple vendors claim to be going gangbusters, with the happy sounds coming out of Vertica and Infobright being echoed by several competitors. Hearsay suggests some other companies in related businesses are doing well too. Depending on who you talk [...]

  • Vertica update

    Updated: 2010-03-19 06:42:06
    I caught up with Jerry Held (Chairman) and Dave Menninger (VP Marketing) of Vertica for a chat yesterday. The immediate reason for the call was that a competitor had tipped me off to the departure of Vertica CEO Ralph Breslauer, which of course raises a host of questions. Highlights of the call included: Vertica had [...]

  • Infobright blog update

    Updated: 2010-03-19 06:42:01
    I often offer that, if a company puts up a sufficiently good blog post, I’ll link to it. Well, I just noticed that Infobright CEO Mark Burton (somewhere along the way he seems to have dropped the “interim”) put up an excellent post last month. Highlights on the market share/sector side include: Infobright’s customer base grew 500% [...]

  • XtremeData update

    Updated: 2010-03-17 22:17:23
    I talked with Geno Valente of XtremeData tonight. Highlights included: XtremeData still hasn’t sold any dbX stuff (they’ve had a side business in generic FPGA-based boards paying the bills for years). Well, there may have been some paid POCs (proofs of concept) or something, but real sales haven’t come through yet. XtremeData does have three prospects who [...]

  • Memcached-based company NorthScale launches

    Updated: 2010-03-16 10:52:48
    NorthScale, a start-up based around memcached, has just launched, two weeks after the Todd Hoff’s post arguing the MySQL/memcached combo is passe’. NorthScale wouldn’t necessarily argue with Todd, arguing that what you really should use instead is NorthScale’s combo of memcached and MemBase, a memcached-like DBMS … … or something like that. I don’t intend to [...]

  • Are You Soft on Your Deletes?

    Updated: 2010-03-15 14:00:08
    Frustrated with soft deletes in SQL, Reeditor writes: In the past, I’ve added a deleted_at (datetime) column and appended “WHERE deleted_at IS NULL” to every query involving that table. But it’s a total pain in the ass, and it’s complicated as shit: there’s always a few queries that are missed, a few developers [...]

  • Toward a NoSQL taxonomy

    Updated: 2010-03-14 16:24:45
    I talked Friday with Dwight Merriman, founder of 10gen (the MongoDB company). He more or less convinced me of his definition of NoSQL systems, which in my adaptation goes: NoSQL = HVSP (High Volume Simple Processing) without joins or explicit transactions Within that realm, Dwight offered a two-part taxonomy of NoSQL systems, according to their data model [...]

  • The Hello World Collection

    Updated: 2010-03-14 02:37:18
    “Hello World” is the first program one usually writes when learning a new programming language. The first Hello World program appeared in chapter 1.1 of the first edition of  The C Programming Language, in 1978. Since then, Hello World has been implemented in just about every programming language on the planet. The Hello World collection includes [...]

  • The Naming of the Foo

    Updated: 2010-03-13 14:47:06
    Let’s start from some reasonable premises. No technology category name is ever perfect. It’s particularly hard to describe NoSQL (Not Only SQL) accurately, given the basic confusion as to what NoSQL is all about. That said, it seems pretty clear that NoSQL is about making big websites (and perhaps other cloud-like installations) run and scale. Dwight Merriman (founder/CEO of [...]

  • Some NoSQL links

    Updated: 2010-03-12 15:51:42
    I plan to post a few things soon about MongoDB, Cassandra, and NoSQL in general. So I’m poking around a bit reading stuff on the subjects. Here are some links I found. A little over a year ago, Julian Browne put up a great post on Eric Brewer’s CAP conjecture/theorem, which provides much of the impetus [...]

  • Learn How to Connect SQL Server to QuickBase via ODBC

    Updated: 2010-03-12 03:53:45
    You can use ODBC (Open DataBase Connectivity) to connect your QuickBase applications to other databases thanks an ODBC Connector from Qunect. If you have data in SQL Server, Access, Oracle, SAP or any ODBC compliant database including Access, Excel and Word you can connect to your data and work with it in QuickBase. How? Join us on [...]

  • Cassandra and the NoSQL scalable OLTP argument

    Updated: 2010-03-02 11:01:13
    Todd Hoff put up a provocative post on High Scalability called MySQL and Memcached: End of an Era? The post itself focuses on observations like: Facebook invented and is adopting Cassandra. Twitter is adopting Cassandra. Digg is adopting Cassandra. LinkedIn invented and is adopting Voldemort. Gee, it seems as if the super-scalable website biz has moved beyond MySQL/Memcached. But in addition, he [...]

  • SQLSaturday Open for Registration

    Updated: 2010-03-01 02:26:12
    On the weekend of May 22, 2010, the Portland Development community is coming together in a way never experienced before. Using the University of Portland campus, SQLSaturday, Portland Code Camp, and Portland Bar Camp are combining and coordinating efforts to bring 800-1000 regional technology professionals together for the opportunity to immerse themselves in seminars, presentations, [...]

  • Data exploration vs. data visualization

    Updated: 2010-03-01 01:29:47
    I’ve tended to conflate data exploration and data visualization, and I’m far from alone in doing so. But a recent Economist article is a useful reminder that they aren’t exactly the same thing. The article makes the same conflation, but while reading it I noticed something interesting. The concrete examples cited are of clever consultants who [...]

  • SQL Injection Prevention Cheat Sheet

    Updated: 2010-02-23 06:09:07
    This article provides a set of simple techniques for preventing SQL Injection vulnerabilities. These techniques can be used with practically any kind of programming language with any type of database. There are other types of databases, like XML databases, which can have similar problems (e.g., XPath and XQuery injection) and these techniques can be used to protect them as well.
