    Updated: 2011-04-26 07:43:49
    The Structured Query Language (SQL) provides database users with the ability to create customized queries to extract information from databases. In an earlier article, we explored extracting information from a ...Read Full Post

  • Application areas for SAS HPA

    Updated: 2011-04-21 09:24:17
    When I talked with SAS about its forthcoming in-memory parallel SAS HPA offering, we talked briefly about application areas. The three SAS cited were: Consumer financial services. The idea here is to combine information about customers’ use of all kinds of services — banking, credit cards, loans, etc. SAS believes this is both for marketing [...]

  • In-memory, parallel, not-in-database SAS HPA does make sense after all

    Updated: 2011-04-21 09:23:41
    I talked with SAS about its new approach to parallel modeling. The two key points are: SAS no longer plans to go as far with in-database modeling as it previously intended. Rather, SAS plans to run in RAM on MPP DBMS appliances, exploiting MPI (Message Passing Interface). The whole thing is called SAS HPA (High-Performance [...]

    Updated: 2011-04-21 07:57:10
    The ACID model is one of the oldest and most important concepts of database theory. It sets forward four goals that every database management system must strive to achieve: atomicity, ...Read Full Post

    A press person recently asked about: … start-ups that are building technologies to enable MySQL and other SQL databases to get over some of the problems they have in scaling past a certain size. … I’d like to get a sense as to whether or not the problems are as severe and wide spread as [...]

  • Endeca topics

    Updated: 2011-04-18 09:02:40
    I visited my then-clients at Endeca in January. We focused on underpinnings (and strategic counsel) more than on coolness in what the product actually does. But going over my notes I think there’s enough to write up now. Before saying much else about Endeca, there’s one confusion to dispose of: What’s the relationship between Endeca’s [...]

  • Netezza TwinFin i-Class overview

    Updated: 2011-04-17 14:59:59
    I have long complained about difficulties in discussing Netezza’s TwinFin i-Class analytic platform. But I’m ready now, and in the grand sweep of the product’s history I’m not even all that late. The Netezza i-Class timing story goes something like this: Netezza i-Class was first foreshadowed in February, 2010. Netezza i-Class customer testing started in [...]

  • Unpacking the EMC Greenplum Q1 sales disaster rumors

    Updated: 2011-04-16 08:21:11
    A well-connected tipster believes: EMC Greenplum’s* revenue target for Q1 had been $35 million. Actual EMC Greenplum revenue for Q1 was $3 million, or maybe it was $8 million. EMC Greenplum had 75 sales teams trying to generate this revenue. In the past I might have called Greenplum for clarification, but they’re not knocking themselves [...]

  • Attensity update

    Updated: 2011-04-14 13:07:11
    I talked with Michelle de Haaff and Ian Hersey of Attensity back in February. We covered a lot of ground, so let’s start with a very high-level view. Two years ago, Attensity merged with two other companies in somewhat related businesses, thus expanding 4X or so in size. Due to the merger, Attensity now has [...]

  • What Starcounter may be up to

    Updated: 2011-04-13 18:55:47
    Starcounter seems to be offering an in-memory object-based/object-oriented/whatever short-request DBMS that also talks SQL. I haven’t been briefed at this point, and hence don’t have detail beyond what’s on their rather breathless web site. I’m guessing this isn’t an H-Store/VoltDB architecture, but rather something more like what Workday runs. Most of the crunch I found [...]

  • ★ Oracle Scheduler Event-Based Jobs are Useful, Here is a Quick Example

    Updated: 2011-04-12 16:37:34
    Here is an example of how you would use event-based scheduling to create an Oracle Scheduler job that has to run after the successful completion of another job. First you let the database user that will own the jobs subscribe to the Scheduler event queue using the ADD_EVENT_QUEUE_SUBSCRIBER procedure. “my_agent”, or whatever name you use, [...]

  • Use cases for low-latency analytics

    Updated: 2011-04-11 04:59:10
    At various times I’ve noted the varying latency requirements of different analytic use cases, which can be as different as the speed of a turtle is from the speed of light. In particular, back when I wrote more about CEP (Complex Event Processing), I listed some applications for super-low-latency and not-so-low-latency CEP alike. Even better [...]

  • Teradata integrates in solid-state storage

    Updated: 2011-04-11 04:56:30
    For once, I think Teradata’s annual hardware refresh is pretty interesting, because of the integration of flash storage into its high-end “active enterprise data warehouse” product line. The essence of the announcement is: Teradata is rolling out a new appliance,* the 6680, which combines hard-disk and solid-state drives, relying on Teradata Virtual Storage. Teradata is [...]
