Piece-wise memory allocation is painful. For a particular project analyzing end-of-life failure modes on satellite switch rings, I have a function that "simply" spins up a list (several million members) of "random" (but balanced) failures to test. It takes minutes to generate the list, most of this is memory allocations going on behind the scenes of the list management. I never bothered to "un-safe" the algorithm. 
And yes, zip is painfully slow. And when I looked at using a serialized zip stream, I discovered it's not a true stream - you can't just shove data in and expect it to stream it out as it works through the compression - the whole damn thing has to be compressed in memory first before it starts spitting out the compressed data to the stream. I discovered that years ago, I think I even wrote an article about it.

For me the most painful lesson with the GZip was trying to zip multiple items, separately, to one stream. That was a mistake! Seems a lot of people have it too.

Keep working on it, Ennis! This industry is pathetic.
I've tried for months to develop a report based on hourly meter readings from our supplier, delivered daily to my mailbox, just to generate a meaningful value for system losses. It turns out that it's impossible. Even the people who use this telemetry data to generate our monthly power bills tell me that it's useless to look at these values, because they can't trust them, and each meter reports a different number of digits' resolution. They actually still rely on monthly manual meter reads to generate our bill! This from fully automated generation and transmission facilities owned and operated by US Government agencies!!!

How about, Just assume .9 power factor for all residential meters and give me the KVA for yesterday but only have KW/h at the hour and Voltage at the hour? And, your not allowed to have an index because it takes up too much space

Well, to be honest, everyone involved including myself understands the difference (which is surprising because I am bad at math). Unfortunately, when you have millions of meters all getting their readings at the hourly level we have to make guesses. I was more surprised that using a constant for power factor was OK, I could understand using a "best guess" based on available data KVA.
Don't pity me too much we can actually bill from our data :p

Yeah, power factors don't change much, except in areas dominated by motors and other highly inductive loads that are switched on and off at various times. I have one substation that has a power factor for the entire service area of 1.000 - consistently! It's almost entirely residential, with a few well pumps, but there's also a 1.5 MG/D sewer plant on the line. How we pull that off is a mystery - just a lucky circumstance that the predominantly capacitive power lines exactly balance the inductive loads. I couldn't design it that way! 
For residential, though, 0.9 is awfully low. Even in summer, when we have summer air conditioning loads that double the usual lighting loads of winter, we run a PF of about 0.95. The rest of the year it's 0.97 to 0.99.

I work for a company where I have rolled our own DES and it has been a successful system for many years. Now we are evaluating whether to build new, retrofit, or purchase something. I am trying to review software but am only finding stuff intended to provide mechanisms to enter fairly simple data, small amounts of data, or surveys. Do you all know of companies that offer software that is truly customizable and intended to allow for hundreds/thousands of complex data edits? I just need help finding the companies that offer those types of systems instead of these data entry creation systems that are intended to allow for name and phone number type entry.

Sounds like you just need to bang together a gui app in Delphi, or visual whatever.
All of those tools make that exact type of operation pretty easy. Drag a bunch of controls, get the tab order right, hook them to a data source and add whatever validation on the 'lose focus' operation.

It's called C#, it's fairly configurable. If you use the ASP.NET module it can be web based as well. A common configuration option is the SQL Server persistence module

I haven't seen anything that can handle the real-life complexities gracefully, which is why I've rolled my own in the past as well, and why I've seen others roll their own as well in other platforms.

That's what I figured. I already wrote my own and we were just evaluating whether there are systems that are already out there that can be configured to do what we want. I didn't have high hopes.
To answer the other 2 questions, I already wrote my own so don't have a problem with that.

Well, why don't you quickly whip together a website and show it to management "Oooh, I recommend THIS product", and sell it to them all over again?

There's an idea.
I don't post much on here anymore so is it strange that you provided the quote in my signature?

Haha. Sadly, I didn't even notice (the font is so tiny). Then again, I'm on here every day, and I'm also seeing if anyone notices my sig and my latest article link.  and votes on the article!!!

Adopt our data service  , which allows batch input as a UI product and also allows custom built input front end system as a service. See here[^]. And here[^] is a more real life example built for StackExchange data dump (it's read only, however).

I am looking for a working in C# that can convert english text that exists in a form to Arabic text before the text is passed to printer. I will be really very very thank full if someone could help me with this.

If you want it transliterated kalb --> كلب then it isn't 100% because there isn't a 1:1 mapping, Arabic doesn't have a ch sound (or character) so this is either usually use a farsi chaaracter (which does) or use the equivalent of t-sh. English lacks several characters especially around the various h sounds. If you are using pure English thing are complicated by the numbers of sounds being attributed to certain groups (e.g. ough[^])
None of the translators work 100% well as there is the added difficulty (over translation to other European languages), due to very little commonality between Arabic and English in vocabulary, syntax or even how the language generally works. This is something you need to consider as the results could be gibberish.

Actually, it was the first word I could think of that transliterated. But then I remembered the "a" isn't written. Fail.
