  1. Required technologies? on Database Bigwigs Lead Stealthy Open Source Startup · · Score: 1

    Any relation to Required technologies? Unfortunately, that's what I think of when I hear about a column store

  2. Re:Might want to consider Data Guard on High Availability Solutions for Databases? · · Score: 1

    Correct you can set it to maximum reliability mode which ensures the the redo logs are written to all sites as the transactions are performed and before they are committed. This can be a big performance killer as you are adding network round trips.

    I definitely agree. steps to getting something new to work in Oracle:
    1. read documentation to get a fuzzy idea of the concepts
    2. search for articles in metalink to find out what you are actually supposed to do
    3. do it and make note of all the errors
    4. find workarounds for the errors
    5. repeat 3&4 untill no more workarounds exist
    6. file tar

  4. Re:some MySQL optimization tips on Improving Database Performance? · · Score: 1

    It can also save quite a bit of IO. Assume all fields are 1 byte, now say you have a table called person which has many to one relationships to 10 other tables. Each of those 10 tables has ten fields. Fully normalized this table is 11 bytes per row. Fully denormalized it is 101 per row. For any query that needs to read more than a small subset of the data (so that an index is not the most efficient path) this means roughly 10 times the IO cost. Even for queries that are more efficient with an index, you still have a large increase in IO because you have less chance that the rows needed will be in the same blocks. Also consider that you might be able to get by without some indexes that you might otherwise need. This frees up the memory used to cache that index for caching other data which could result in a better performing system overall. Throw in the performance impact of the integrity constraints or cascading updates for the denormalized table and you can really end up with terrible performance. It is a more complicated issue than it seems on the surface.

  5. Re:No, I didn't think that on Our Brains Don't Work Like Computers · · Score: 1

    Yes they are. I think it has to do with the influence from all the binary devices they interact with causing them to never develop more than two shades.

    I'm 27 and I must be somewhere in the middle because I don't seem to have enough shades to grok the use of the word "preciously" in your post.

  11. Re:Access is evil on KDE Knoda Meets MS-Access in New Release · · Score: 1

    Scary, this is exactly what I would have posted, with the possible exception of the example. There were just so many horrid bugs to work around. I actually heard my boss make the comment that programmers are only worth a third of the time they bill for. I corrected her saying that we were only worth a quarter of the time we billed for and the joy of having an app done in access was worth the other three quarters. I think my most annoying bug in terms of shear stupidity was "if (bVar)" as apposed to "if (bVar = True)" causing access to go into a tight little loop doing nothing but minimizing the window. Of course this did not happen when debugging.

    No, win2k is much too recent. What you need to do is get a version of windows that is old enough to no longer be targetted. You still want something with a fairly comprehensive feature set, so I'd recommend Windows ME.
