DataCollector

When I first posted about my DataBridge utility I mentioned the DataCollector, which was a Java-based framework for quickly building apps that interacted via web services with a third-party CRM services provider.

In this post I’ll introduce the DataCollector framework. For obvious proprietary reasons, this will be fairly generic, but I think the basic architecture is worth sharing. It’s a nice example of using factory classes.

Last time I started the story of my DataBridge application — a Java-based tool for transferring and transforming tabular data, such as TAB, CSV, and XML files. It could also read from and write to ODBC tables.

The app itself was just a framework that implemented a basic IPO model to transfer data. The details were up to the Input, Process (in this case, Mapping), and Output, drivers loaded at run time.

The last story was about PF.EXE, a file-processing utility I wrote for my own use way back when. That one was a combination of C code and 8086 assembler and written for MS-DOS (worked fine in Windows). It read and wrote disc files and had a toolkit of things it could do to them, depending on command line switches.

Many years later, using Java, I created more capable versions, the culmination of which was a suite called DataBridge. It turned out to be some of the most valuable work I ever did for The Company.

Anyone Can Code?

There’s a general ethic these days — that anyone can code — and like a lot of things, there’s some truth to it, but also some silliness. As usual, it really depends on what we mean by “anyone can code.”

If we mean it in the same way we might say, “anyone can drive,” I think it’s silly. But if we mean in the same way we might say, “anyone can doctor (or lawyer),” well, then I still think it’s silly.

xkcd #2030 by Randall MonroeI cracked up when I saw this recent xkcd cartoon. Randall Munroe rarely fails to deliver, but this one especially caught my eye. It’s painfully on-point and quite dismaying on at least two points:

Firstly, that it should still be this bad given all the time, money, and attention, it has received is reason alone for dismay. Part of the problem here may be that we haven’t admitted how hard software is to get right.

But, secondly, software is central to our lives now — far more than airplanes, and even more likely than elevator rides. You might ride an elevator, at most, a dozen times a day, but software enters your life more times than that.

Especially if you use a mobile computing device!

Getting to the Next Hill

Last week I took my car in for scheduled service, and when I asked how long it might take, the guy said it was specified as one-and-a-half hours of labor. He could do that because there are thousands upon thousands of data points where a competent mechanic has performed that exact service, so there is a very clear idea how long it takes.

But ask a researcher how long it will take to find what they’re looking for, and the answer is usually, “I have no idea. I’ll know after I find it.” The path a researcher follows is usually new and unexplored, so it’s impossible to predict how long the path actually is.

Creating new software is much more like research than auto service, because it involves traveling unknown ground. Despite this, software development managers often act as if new development is predictable.

It often isn’t!

Computer programming is hard!

Computer Programming is hard! It’s at least as hard as what commercial architects do, and I will argue that it’s as intellectually difficult as what doctors and lawyers do.

Many people think it’s easy, because they know some nine-year-old who “programs,” but there’s a difference between fooling around with the computer and building good software applications.

Managing Complexity

Somewhere I heard someone claim that: “Programming is an exercise in managing complexity.” The word “is” makes the sentence slightly ambiguous. It could mean: “Programming is just an exercise in managing complexity,” implying that that’s all programming is. Or it could mean: “Programming is an exercise in managing complexity (in addition to other things).”

I would absolutely disagree with the first interpretation; programming is definitely more than just managing complexity. On the other hand, managing complexity is a huge aspect of programming.

At some point it strikes you. For some it  happens early in Computer Science class after hearing a professor say it for the umpteenth time. For others it happens when hearing it come from their own mouths for the umpteenth time. The Universal Answer to any (and all) computer (science) question(s).

“It depends.”
