Re: [PSUBS-MAILIST] operational sub parameter archive.



Well, Im not trying to lay down the law on what kind of data should be entered. I suppose whatever data people feel themselves is relevant, or what they would like to show/brag about. As you say, statistics are our friend.. outliers are especially welcome. From what I understand about Busby, I would guess that all that stuff is valid, I leave it up to you. Whatever you think will help!

The info is simply listed on a web page. The 'format' is text. I deliberately wanted to leave it non-specific, since I personally have my own data-analysis software, which is probably totally different to everyone elses, and the same for everyone else. Once the layout of the text is consistent, batch jobs or scripts can extract the info you want and re-format it...

Very cool project. Are the specs for the subs in Busby within the scope of your project/analysis? If I'm understanding what kind(s) of correlations you're trying to explore (statistics applications are our friend), it seems as though Busby would be a totally valid source of data ... reference points are reference points ... not to mention that it would just be cool as a referential database. Realistically speaking, in terms of technological levels, some of the psubs built or being built by members or otherwise are implemented as well if not better than some of the arguably technologically dated university-/institution-level submersibles listed in Busby. Likewise, historical subs with documented specs, including non-nuclear military subs like many of us have discussed building replicas of, would be an equally nice feature. That would also give you the capacity to explore trends also as a function of time. I would have *loved* to have had access to a database like that a year or more ago ... back when I had no real concept of the scope of the project I was undertaking. It would have given me a lot of ballpark perceptions on things like vehicle mass relative to size/passengers, hull thickness vs. depth capacity, batteries/voltages vs. speed, etc. Damn ... I've almost talked myself into feeding the data into MS-Access myself, maybe with a suitable picture of each. BTW, what format is the website database? Warm Regards
