Introduction Today I thought I'd talk about a neat design pattern that doesn't seem to get much love: In its fullest form it's also sometimes called the Prototype Pattern.
People use this pattern all over the place, and I'll give you a nice set of real-life examples in a little bit. It's a design pattern that's useful in every programming language, and as we'll see shortly, it's Disk operating system essay pretty darn useful as a general-purpose persistence strategy.
But even though this pattern is near-universal, people don't talk about it very often. I think this is because while it's remarkably flexible and adaptable, the Properties Pattern has a reputation for not being "real" design or "real" modeling.
In fact it's often viewed as a something of a shameful cheat, particularly by overly-zealous proponents of object-oriented design in language domains or relational design in database domains. I hope to offer a different and richer perspective here.
With luck, this article might even help begin the process making the Properties Pattern somewhat fashionable again. Three Great Schools of Software Modeling Before I tell you anything else about the Properties Pattern, let's review some of the most popular techniques we programmers have for modeling problems.
I should point out that none of these techniques is tied to "static typing" or "dynamic typing" per se. Each of these modeling techniques can be used with or without static checking.
The modeling problem is orthogonal to static typing, so regardless of your feelings about static checking, you should recognize the intrinsic value in each of these techniques. Class Modeling You know all about this one.
Class-based OO design is the pound gorilla of domain modeling these days. Its appeal is that it's a natural match for the way we already model things in everyday life. It can take a little practice at first, but for most people class modeling quickly becomes second nature. Although the industry loves OO design, it's not especially well liked as an academic topic.
This is because OO design has no real mathematical foundation to support it — at least, not until someone comes along and creates a formal model for side effects. The concepts of OOP stem not from mathematics but from fuzzy intuition.
This in some sense explains its popularity, and it also explains why OOP has so many subtly different flavors in practice: Industry folks can never quite agree on what OOP is, but we love it all the same.
Relational Modeling Relational database modeling is a bit harder and takes more practice, because its strength stems from its mathematical foundation. Relational modeling can be intuitive, depending on the problem domain, but most people would agree that it is not necessarily so: Object modeling and relational modeling produce very different designs, each with its strengths and weaknesses, and one of the trickiest problems we face in our industry has always been the object-relational mapping ORM problem.Oliver Pell Cryptology.
This is an essay I wrote for a mathematics essay prize. We had a number of possible topics to choose from and I choose cryptology, because I already had a passing interest in thanks to my attempts to code encryption algorithms for my computer programs.
Operating System An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs. It is a program designed to run other programs on a computer. The operating system is an essential component of the system software in a computer system.
