@TheUnhandledException Yep, and that's what I have right now. The problem is I need to filter the results on some of that data; my boss' solution is to basically just dump raw data in the table, but that will cause the table to grow quickly and makes things very denormalized. :(
@Tim: What is this data like? String data? Arrays? Objects?
 
Tim
The data is tabular, and consists of numerical and string data only.
 
Could you generate checksums out of it?
That way you could store the checksum in a table, and easily search for a given row as to avoid duplication...
Or, you could store the data elsewhere, outside of the database, and just store the checksum, and use that to look it up later
 
Tim
Yeah, that'd be possible.
The first part anyway, the current storage format is not friendly to random access, heh.
 
Just brainstorming here a bit, since I don't know the specifics of your situation
 
Tim
Yeah, I might be able to illustrate the problem a little better, one second. :)
(Also, thanks a lot for the help!)
 
3:34 PM
Sure thing, glad to be of assistance
 
brb
 
Tim
Alright, now that I didn't break Google Docs
 
LOL. Let me have a looksee
 
Tim
(and don't worry, the data isn't "real")
Basically, the data comes in the form on the Details tab
And I need tables that will be flexible enough to handle that and produce the first two tabs as well.
 
OK... so...
I think the message column from the details tab should be it's own table
That will save a lot of space
 
Tim
3:48 PM
Yeah
 
As for the data itself, is that the Value column of the Details sheet?
 
Tim
@TheUnhandledException Yep. The values correspond to the column names in the Variable column
The value comes in key-value pairs, it's just flattened for the sake of display there
 
Hmmmm... I understand now
 
Tim
Yeah, there's a ton of repetition, but only in the context of a single source (identified by the Name column)
 
Yeah, I'm thinking a data table, with columns for variable and value
and then an error_data table, containing error_id and data_id
so a one-to-many relationship between error messages and data rows
 
Tim
3:56 PM
So error_data would have a record for each record that has an error of a given type then right?
 
@Tim yeah
so that first row in the details column would have one error row and two error_data rows
 
Tim
@TheUnhandledException Alright, great. That was close to where I had gotten, but for some reason my brain wouldn't make that extra leap. :)
 
the two error_datas would be (Label,BRTHDTC),(Variable,BRTHDTC)
so for example, data id#1 = LABEL,BRTHDTC
data id#2 = variable,BRTHDTC
Then you can have any number of errors refer to those
Rows 57-66 are a better example
You'd only store "PC" and "PCSEQ" once
 
Tim
Right
 
maybe data ID#22 is RDOMAIN,PC. Then all the errors can have error_data id= the error row ID, data_id=22
it will still be a ton of data, but at least it won't be duplicated
@AidenBell if you're around, do you agree?
 
Tim
4:02 PM
@TheUnhandledException Yeah, that definitely works. Awesome!
 
cool
Feel free to ask others for help, like I said, I've designed quite a few databases but am not an expert! :-)
I've learned what I needed to, I'm sure others could critique my suggestions :-)
 
Tim
Yeah, I was too unsure of myself here to feel confident about trying anything due to the issues that might arise from a terrible design, heh. So your insight should help me at least get something workable, which we're then going to pump full of data to see how it performs :)
 
@Tim Awesome! I hope it works out for you
 
Tim
@TheUnhandledException Thanks, and thanks again!
 
This room isn't very popular yet, I hope moving it to SO chat will gat more attention/people in here
@Tim You're very welcome
 
Tim
4:08 PM
@TheUnhandledException Yeah, admittedly I wasn't aware that it existed until now, heh.
 
@Tim I should drive more people in here
 
@TheUnhandledException do you know when SO Chat will go live?
 
Problem is, if nobody's here to help, it doesn't do much good. catch-22 :-)
@PiersMyers I've been asking for weeks
Looks like any day now
 
Tim
Yeah, I'm going to leave myself parked in here now. ;)
 
@TheUnhandledException what's the password?
 
4:09 PM
@PiersMyers Not this again! :-D
(We were trying to guess it for like 3 hours this morning in The Tavern)
 
hehe, I missed that
