The balance between architecture and code

"Design (architect) from the top down, then implement from the bottom up."
While that makes sense in the abstract, I think it's misleading and results in compartmentalization. It's hard to express in words, but the activity of architecture and implementation is for me more of a process of moving around a lemniscate with fractal properties.

I think that it can only be done with proper planning or maybe with lots of experience if you start with a design that lends itself to scalability. Often the requirements are not well defined or understood and it leads to an implementation that isn't ideal. That's where v2 comes in - redoing the way it was supposed to be done :)

That's the funny thing - it only takes a few lightweight architectural implementations to achieve a good amount of scalability, regardless of the project. The things that promote scalability tend to be completely agnostic to the type of project, at least in my experience.

After a recent post, it occurred to me that we rarely see a good balance between architecture and code. I often see: under-architected, over-coded. But I've also encountered: over-architected, over-coded. Personally, my goal is always "under-coded" (meaning, as little code as possible), and I find that that drives a certain amount of architecture, usually during the coding, not before the coding. So it strikes me that the missing category: well-architected, well-coded is something that must be done simultaneously. Not the "architecture first" approach, not the "code as a hack" approach, but rather, while coding, considering where "architecture" can facilitate "well-coded." And by architecture, I don't mean gloriosky layers of abstractions, thousands of interfaces, DI and IoC. To me, architecture includes writing small functions and maximizing code re-use (there are more, but I'm writing a post in the Lounge, not an essay.) Thoughts?

Quite often Architecture changes meaningfully after the coding starts.

I've concluded that there are common architectural elements that can definitely be reused, and yes, there are application-specific architectural decisions as well, though in my experience, many of those can become reusable (if not in code, at least in concept) implementations.

Client-Side Type-Based Publisher/Subscriber, Exploring Synchronous, "Event-ed", and Worker Thread SubscriptionsThe metaphor that comes to mind is a diamond cutter: you need a lot of expertise and a lot of patience to do it right. But polishing each face of a diamond takes time and perseverance and both of them are in short supply in the software world. What is the chance of nailing perfectly the architecture the first time around? You see the pieces that can be reused and where each one fits only after you've travelled the design ladder from top to bottom and from bottom to top a number of times. On the other hand how many times do you have the chance to get back to a project and do major rework? In most cases the economics of the game forces you to leave unfinished bits and pieces and you move on with the sad taste of not having done your craft as well as you wanted.

Client-Side Type-Based Publisher/Subscriber, Exploring Synchronous, "Event-ed", and Worker Thread SubscriptionsHaving never actually learned to code. I just do it. So I get an image in my mind's eye (poetic interlude) and keep also the idea that I'll have to extend it at some point; it, in this case, being just about everything. It causes a good deal of abstraction and that does increase the code size a bit . . . at least at first. The whole thing about coding (not discussing language implementations) is that doing it right is just following the sensible path. Experience has embellished the path (not necessarily the code) to take into account what will happen (i.e., users) and what is likely to come. I wouldn't say it fits any particular model but it does seem to work.

And if you have a crowd, you need an application framework. If there isn't one that's a good fit, you need to build it yourself. This needs to be done by a small team, some of whom are using it to build a few serious applications so that it evolves into something relatively stable before the crowd is unleashed.

Ditto. Less, is easier to understand, maintain, service and makes it easier to track bugs. As far as I know, this is the gold standard.

Yeah. This bugs me. One of those three layers is SQL Server. And still people insist on adding another layer, because the docs say so. No! SQL Server is the abstraction to how stuff is stored on disc, you don't need that layer that does absolutely nothing.

Use them if needed, don't use them just to have it. Only use it if needed.

To clarify something else; code re-use, means calling an existing function, not to Ctrl-C, Ctrl-V it! You call the original, having one point of maintenance. Not copying the same bloody statements all over the place.

I had many bosses; one would state what he needed, and demanded minimalism. He'd just say what you should output, from his input and that's it. How you got there, was your problem (that's 25 years ago). It worked like magic. My last came with patterns, he'd paint this big picture of interactions, told everyone which parts to build, and off we was. His magic was a level up. There also was two VB6 projects. Not gonna say anything about those, as the managers were as outdated as the language. I mean, really, storing 31 booleans for each member each day, and convert them to strings? That was the only person I met with the architect title.

But how would you? : 1) sell books 2) sell tickets to your conferences I mean without that you're just writing software and getting stuff done. What you need is a system that can only be described in books and at conferences. :rolleyes:

It's kind of related but different enough that I thought it warranted its own post. Anyway, I agree with you that architecture is something that is done throughout the lifecycle of the project. You do want to front load your project with a design phase, but you don't freeze the design before you write the code. I think people tend to believe you do. You freeze *features* hopefully. But design is living.

For so long I've been an interface aficionado. But I keep rediscovering C++ and with it generic programming, and template based metaprogramming which I find profoundly useful for generating efficient flexible code I couldn't easily make otherwise. The powerful thing about this is that this "polymorphism" is source level, not binary (vtbl based). The problem with this is all of this "polymorphism" is source level, not binary. The compiler checks it, but only if you use it by instantiating it and that means you might not catch errors in your code until well after your code is being used, even in production, because that part never was compiled. So you lose a big advantage of interface based programming when you're using generic programming and template based polymorphism to implement your "interfaces" which again are source level, not binary. I can't resist the urge to use it though. The power. The efficiency. The dark side... it beckons!

And just to complicate things I'm going to chime in to say that not only does fewer lines of code not mean more efficient, the opposite is more often the case, because naïve algorithms tend to take less code but do more work. Because of that, the framework code is often the best choice, even for performance reasons. I wrote a B-tree library in C# for holding millions of rows of data in a dictionary. The standard dictionary outperformed it for small sizes (of course) and kept up with it all the way until millions of rows at which point it still wasn't much worse, leaving the only advantage of my b-tree was the storing of the data in sorted order. Don't underestimate a good framework. Lean on it hard.

The prototype was a more stable solution.
