The mostly used tools for communicating architecture design is class diagram, package diagram, sequence diagram, delopyment diagram. And in some cases flow chat is also used for important business process modeling. For now I think it is OK. But I am wondering if the...
I understand that only one instance of any object according to .equals() is allowed in a Set and that you shouldn't "need to" get an object from the Set if you already have an equivalent object, but I would still like to have a .get() method that returns the actual instance of the object in the Set (or null) given an equivalent object as...

For the first UI design I would like to populate my windows and dialogs with lookless controls. The controls may not be styled at all (no XP or Vista style). Ideally, they look so minimalistic (black-and-white rectangles) that it's clear where a text box, a button or a scroll bar. Because I'm working with Visio, my first idea were to l...

What are the constituents of a good relational database design? I'd want to ask this question in a bit unusual way, lets see if anyone likes the idea. Also read on to see how it's not a duplicate of the question about DB design best practices (or any other question for that matter). The idea is that as a result of voting we will have co...

The readership would involve myself (in a future time), other developers (currently and in the short-term future), as well as end users.

What's the difference in Java between a utility class (a class with static methods) and a Service class (a class with public methods that provides a "service"). For example, one can argue that a cryptographic object (providing methods to encrypt, decrypt, hash or get a salt value) is a Service provider, but many group this functionality...

Are there any guidelines/recommendations on how long the input fields should be on HTML forms. Specifically: Viewable length (the length of the input field the user can see on the screen - without having to scroll horizontally. i.e. SIZE, not MAXLENGTH) Capture length (the number of characters the HTML form will save to the database) ...

Now, to obey Single Responsibility Principle, I want to have the following classes: MailerSender, MailProvider and EmailObject.

I have a C module which is created by the Real-time Workshop based on a Simulink Model. This modules provides three public functions: int init(); int calc(double *inputarray, double *outputarray); int term(); Based on the contents of the outputarray, I can model a class called OutputThing. I want to integrate those functions in a wra...
Which would you recommend - a deep objects hierarchy (where each object hold a reference to it child objects), or flat objects (where you provide services to retrieve child objects)? Let's assume that you are creating a database management application. You will have objects such as: Server Database Columns Views Which option would y...
