LOL! I think he omitted that table Smile | :)

That looks a lot like the Oracle tables at the company that I used to work at. I really hated having to query that database. You didn't have any clue as to what each field was being used for. Dead | X|

This table design could be used to reduce the size of a database and improve manageability that contains unknown/highly dynamic structures

I will make an assumption (the only one in this post) and say this project deals with loading structures that change frequently. Could be wrong and be looking at a noob's 'work of art'

There are three approaches for highly dynamic structural data:

1. Dynamically create the schema's based on external blue-prints, giving real names to columns. This might not be the best solution for a few subtle reasons which have to do with the degree of knowledge by the end-user's of the database and any planned api's or DAL's. Generating the dynamic schema prior to loading data can be done in two modes: 1. immediately, where new un-generated schemas are encountered and have to be generated on the spot. This presents an obvious problem if you have multiple clients performing the imports for a single database (similar to SETI). Such as, what if two clients encounter the same type of schema that isn't in the database yet, only one schema should be generated. 2. Delayed, where after loading many imports and discovering that some new files failed to match any current dynamic schema, the database user can manually kick off schema generation and then attempt a reload of those files that failed earlier.

2. Contain the all the data into a single table (or a table for each datatype) with four columns (ImportFileId, RowId[original structure's], ParameterName, ParameterValue). This solution gobbles up WAY MORE disk space (more than doubles the space requirement of the solution given above as well as in #1 (In oracle, at least, the remaining columns that are null take up no space.) This is considered serializing the data, also could be called demuxing.

3. Then there is the solution above. The only requirement is that any API must map the ImportFileId to some blue-print of the columns involved. This solution saves much more space than #2 AND has the added benefit of simplicity on the database up-keep side (ie. no schema generation prior to import)

I've been down this road dealing with a database with over 400,000 actual unique fields of data. We actually used option #1 for good reason. So, I wouldn't knock it just because it's different.

Yeah, that got me there, the other didn't.

Right! Message edited.

Wow...Just wow !!! I live for piece of crap like that... OMG | :OMG:

And after the laughter eventually one thing crosses my mind.

"Is that man paid for his programming services ?".

I have fallen in love in this part:

int num = 0x20;
int num2 = num / 4;
int num3 = num / 2;
int num4 = 13;
int num5 = 0x37;
int num6 = 10;
int num7 = 10;
double num8 = double.Parse(this.lblZoomFactor.Text) / 100.0;
int num9 = (int)(num * num8);
int num10 = (int)(num2 * num8);
int num11 = (int)(num3 * num8);
int width = (int)(num5 * num8);
int num13 = (int)(num6 * num8);
int height = ((num4 + num9) + num10) + num11;
int num15 = ((bitmapWidth - 0x10) - (2 * num13)) / width;
int num16 = (bitmapWidth - (2 * num6)) - (width * num15);
...
int num18 = (num17 / num15) + 4;
int num19 = num18 * (height + num13);
int y = num13;
int num21 = 0;
num21++;
int num23 = num21 % num15;
...
int num25 = (y + num4) + num10;

(not so funny, though)

Parts of it look like some autogenerated VS code Big Grin | :-D

modified 19-Nov-18 21:01pm.

I think, this code is a result of Reflector disassembling Big Grin | :-D

Saw this one yesterday via DotNetKicks[^]:

public static class NumberHelpers
{
   public static ApplicationException EvenOrOdd(int integer)
   {
      if (integer % 2 == 0)
      {
         return new ApplicationException("The integer is even.");
      }
      else
      {
         return new ApplicationException("The integer is odd.");
      }
   }
}

Usage:

protected void btnTest_Click(object sender, EventArgs e)
{
   try
   {
      throw NumberHelpers.EvenOrOdd(Convert.ToInt32(txtIntToTest.Text));
   }
   catch (ApplicationException ex)
   {
      litResult.Text = ex.Message;
   }
}

Brilliant! I'm going to utilize this beautiful exception-based development pattern into our code base immediately!

Can't you see the really GOOD think this solution is?

If the string is not a number you will also get the right message. It can't be simple, can it?
