what is the concept for interface design?
602964
In general, an interface is a device or a system that unrelated entities use to interact.\n\nSo we treat it as a type. An interface defines methods which are never implemented. \n\nFor example, we will do a Interface of a Database. A database can SELECT, DELETE, UPDATE, and INSERT.\n\nAs you know we have many databases like MySQL, Postgres, MSSQL, Oracle, Derby, etc...\n\nNow as a designer I want to make one standard interface that has those methods unimplemented inside. Now when I want to add a driver (one of the databases) I just Implement that Interface.\n\nNow when I program... I just call that interface and Use those methods... If I want to change the Database Engine to someother engine, nothing changes cause the Database Class implements the Database Interface . THEY MUST FOLLOW THOSE Method names. If they do not... a error will return\n\nI hope you understand now!

web designing is the physical appearance of the page.  The colors, the layout, the pictures, etc.\n\nWeb programming is the back end, or behind the scenes things that you won't see.  Such as the processing of a e-commerce cart, a log in, a validation.  All of those things are programming.\n\ndesign in the aesthetics of the page.

and this is a computer programming/design question because ..?

A myth, mostly.  The idea is that the programmers anticipate all the various things the user will want to do, and make it easy to do them.  A truly user-friendly interface would name the menus something the user would recognize as being the place to find what he is trying to do, would put them all out there where he would be expected to look for them, etc.  It would also guard against accidently screwing up, by having "are you sure?" protection on things.\n\nHA!  I have yet to run a program I couldn't screw up, or rather screw up my document or my data in no time flat.  And I have yet to find anything useful in a "Help" menu.  Mostly the way I get by is lots of trial and lots of error, and bugging the people who know to tell me.\n\nOh, for the days of user manuals and tutorials!!!

I assume this is in reference to microsoft office forms designing, I've provided a link to a demo.

First you should be well aware of the design patterns such as factory , strategy patterns etc.. there are many design patterns available on net. which can fulfill your needs. \nFirst Head Design Pattern is a best book for this.

Human technology interfaces can also refer to a broad range of biomedical devices. For instance, the Cyberhand Project is an attempt to interface technology in the form of a mechanical prosthesis with a patient's central nervous system.

well designed would mean easy move ment which means that your software has to be easy to operate even for a noob and btw looks are a secondary issue.first go in to make the menu's and other links better and then try putting textboxes around you software to make it easy\nBest of luck

Chosing Interfaces vs Abstract Classes in not an eithier or choice, consider for example , if your applications functionality is likely to change in future then you could probably define the methods in an interface and let the functionality be defined by the class that implements the inteface,and thereby still maintain compatablity after revision, but on the other hande lets say, in case you want to write a class that forces a certain behaviour, ie , the behaviour remains constant, then you are better of defining it as an abstract class. Abstract classes are excellent ways to create planned inheritance hierachy, and remember a class that creates an abstract method can also call that method.\nAs a rule try to remember, if you are into creating API's then interfaces are the choice , on the other hand if you are building something like an application framework, consider using abstract classes to force certain behavioural characteristics,into all classes that extend your abstract class and let that class define the rest.

It's need more design, looks fine, but looks like a simple Web page. The Idea is good, work hard. There are more features?

An interface is a collection of method signatures that are defined. Objects can indicate that they implement an interface -- this means they agree to provide the methods that appear in the interface.\n\nFor example, perhaps I have an interface called Printable that contains a single method print. Note the interface has no actual code for this method, just the signature (name, return type, argument list, etc.).\n\nThen if an object implements Printable, it is promising to provide a print method with the right signature.\n\nNow, any piece of code can get a reference to the object and treat it as though it were a "Printable" object -- there isn't any such class, but in this context, the interface is like a class.\n\nThis allows you to create lots of class hierarchies with different roots, but use any object as "printable".\n\nNote that some interfaces have no methods at all -- just the fact that they implement an empty interface indicates something about the object.

Is this a quiz a from the actual event? If not I'll take my guess at what a good designer should be:\n\nCreative (can think outside the box)\nWork well in teams (can communicate and accept criticism)\nUnderstands users needs vs. wants \nHas vision (can visualize the solution and can with the help of other execute)

Just write the document to describe each item changed and or any changes in functionality. Then provide a screen shot (ALT + Print Screen) for each of the changed items.\nGood luck!

Choosing interfaces and abstract classes is not an either/or proposition. If you need to change your design, make it an interface. However, you may have abstract classes that provide some default behavior. Abstract classes are excellent candidates inside of application frameworks. \n\nAbstract classes let you define some behaviors; they force your subclasses to provide others. For example, if you have an application framework, an abstract class may provide default services such as event and message handling. Those services allow your application to plug in to your application framework. However, there is some application-specific functionality that only your application can perform. Such functionality might include startup and shutdown tasks, which are often application-dependent. So instead of trying to define that behavior itself, the abstract base class can declare abstract shutdown and startup methods. The base class knows that it needs those methods, but an abstract class lets your class admit that it doesn't know how to perform those actions; it only knows that it must initiate the actions. When it is time to start up, the abstract class can call the startup method. When the base class calls this method, Java calls the method defined by the child class. \n\nMany developers forget that a class that defines an abstract method can call that method as well. Abstract classes are an excellent way to create planned inheritance hierarchies. They're also a good choice for nonleaf classes in class hierarchies.

microsoft offer web page designing and you may be able to download what you are after from them, or try this site http://www.buttons-4-less.com/ cheers good luck

Everythiny you want to control with a computer needs an interface -you can build all the progtams you want, if they aren't actually controlling a switch/switch gear/ motors/sensors etc etc then the computer (program) is just a useles box of instructions \n\n- Interfaces COST money unless you are MacGyver ;)
