Three Essays by Jack W. Click here for the introduction. Numerous articles and books have appeared describing how to apply the new techniques. In general, the questions of whether O-O techniques are just hype have been replaced by questions of how to get the benefits with the least amount of pain.

Object oriented techniques have been around for some time, but this exploding popularity seems a bit unusual.

The Law of Accelerating Returns | Kurzweil

Why the sudden interest? All kinds of explanations have been offered. In truth, there is probably no single reason. Probably, a combination of factors has finally reached critical mass and things are taking off.

Again, there are probably a number of reasons why, Hardware software requirements essay I want to suggest an answer from a slightly different perspective: If that comment seems a bit unusual, it is deliberate.

What I want to do in this article is take a look at the relationship between programming and software design.

For almost 10 years I have felt that the software industry collectively misses a subtle point about the difference between developing a software design and what a Hardware software requirements essay design really is. This lesson is that programming is not about building software; programming is about designing software.

Years ago I was attending a seminar where the question came up of whether software development is an engineering discipline or not.

While I do not remember the resulting discussion, I do remember how it catalyzed my own thinking that the software industry has created some false parallels with hardware engineering while missing some perfectly valid parallels.

In essence, I concluded that we are not software engineers because we do not realize what a software design really is. I am even more convinced of that today. The final goal of any engineering activity is the some type of documentation.

When a design effort is complete, the design documentation is turned over to the manufacturing team. This is a completely different group with completely different skills from the design team.

If the design documents truly represent a complete design, the manufacturing team can proceed to build the product. In fact, they can proceed to build lots of the product, all without any further intervention of the designers. After reviewing the software development life cycle as I understood it, I concluded that the only software documentation that actually seems to satisfy the criteria of an engineering design is the source code listings.

There are probably enough arguments both for and against this premise to fill numerous articles. This article assumes that final source code is the real software design and then examines some of the consequences of that assumption.

There is one consequence of considering code as software design that completely overwhelms all others. It is so important and so obvious that it is a total blind spot for most software organizations.

This is the fact that software is cheap to build. It does not qualify as inexpensive; it is so cheap it is almost free.

If source code is a software design, then actually building software is done by compilers and linkers. We often refer to the process of compiling and linking a complete software system as "doing a build".

The capital investment in software construction equipment is low—all it really takes is a computer, an editor, a compiler, and a linker. Once a build environment is available, then actually doing a software build just takes a little time.

Another consequence of considering source code as software design is the fact that a software design is relatively easy to create, at least in the mechanical sense. It is tempting to ask if there is any other engineering discipline that can produce designs of such complexity as software in such a short time, but first we have to figure out how to measure and compare complexity.

Nevertheless, it is obvious that software designs get very large rather quickly. Given that software designs are relatively easy to turn out, and essentially free to build, an unsurprising revelation is that software designs tend to be incredibly large and complex.

This may seem obvious but the magnitude of the problem is often ignored. School projects often end up being several thousand lines of code.

There are software products with 10, line designs that are given away by their designers. We have long since passed the point where simple software is of much interest. Typical commercial software products have designs that consist of hundreds of thousands of lines. Many software designs run into the millions.

Additionally, software designs are almost always constantly evolving.Computing is any activity that uses r-bridal.com includes developing hardware and software, and using computers to manage and process information, communicate and r-bridal.coming is a critically important, integral component of modern industrial technology.

Major computing disciplines include computer engineering, software . Contrary to popular belief, architecture is an important aspect of agile software development efforts, just like traditional efforts, and is a critical part of scaling agile approaches to meet the real-world needs of modern organizations.
