1NF: Data is atomic (so everything is broken down as much as it can do, like address is stored as 'address line 1' 'address line 2' etc) Field names are unique There is a primary key
2NF: Must be in 1NF (so it needs to follow all the rules above) All non-key attributes/fields relate to the primary key
3NF: Must be in 2NF All non-key attributes/fields must fully depend on the primary key
I know its not the complicated version of 2NFand 3NF but youll still get the marks in the exam if you put that. So all you have to remember is that 2NF is relate and 3NF is depend
Yeah he is, but i dont wanna revise loads on those subjects but then it doesnt come up in the exam
I guess if you want to take that risk,but i would be vary of what people have claimed on the internet, as some guy a couple weeks back claimed to be cheif examiner, and wanted us to pay him for the paper...
So with wimps its windows, icons, menus and pointers.
In the exam they'd probably ask you to describe the characteristics of a WIMP interface, so you just basically take each point and expand on it
So its a GUI (graphical user interface) so its based on graphics rather than text
A window is basically the screen that opens when you click on an application like a tab sort of thing so that you can use the software The icons are used to represent an application to the user so that they know what it is before they open it, so like with access its a key symbol The menu provides different options, that can be selected by the userIt uses pointers, so basically it reflects the users movements and reflects them on screen so that the user can make selections
Need help with static and dynamic parameters and graphic libaries
Static - Is when the information will not change when its produced, for example a book, it is only accurate the day it was printed.
Dynamic - Is information that is constantly changing and updated for example a website.
Parameter - Is when you enter a value into a query ( basically search for something ) and the result is shown that you searched for << I think not to sure.
Graphics library - Collection of pictures that are standard symbols in the industry?<< Sorry for the crap definition.

I thinks it gonna be a nice exam but grade boundaries are gonna be high, The pattern has always been low,high,low last years was very low so I think it will be high this time
Yes...majority of the time. The attachment I put up is Paul Longs predictions and it is colored according to the key he provided. The yellow ones are ones where he has got wrong in the way. But remember these are PREDICTIONS; not definite.
They distribute network packets between devices. They do the same job, but a hub distributes the packets to all devices, a switch learns the location of devices using a routing table and only sends it to the destination.

Can someone give the advantages and disadvantages of graphic libraries?
ADVANTAGES INCLUDE: -Consistent designs -Thumbnails -Range of images -Integrated with software -Readily available -Vector graphics -Up to date product ranges
DISADVANTAGES INCLUDE: -Software updates to keep symbols up to date. -Inconsistencies between organisations and nations -May not have the required symbol
Information Data sources Static data and dynamic Validation Characteristics of applications Adv/Disadvantages of tailoring Consistent house style Masters,style sheets,templates Modelling software characteristics spreadsheets for simulations Releational database terminology Identify database features and ERD Characteristics of normal forms Select data tyoes Clipart and thumb nails Graphic libraries Non linear and hierachical presentation Impact of ICT,Future developments and Ict laws- There will almost definitely be on discuss question and a big explain question using 3.1.6.a, b or c- if in section a, its unlikely to be about social networks,internet or cmmunicating with customers, there will almost definitely be a question about law (REVISE THE LAWS ITS VITAL) even if its not a discuss question.

I don't think so as the attachment I put up were Paul Longs predictions (...gave us a copy when he visited our colleges...) of what is likely to come up, what could go either way and what is less likely to come up.
Some specification points for Likely to come up is not shown in the list above. But not entirely sure where the user got these predictions from.

In your attachment, the cells highlighted in green are the topics most likely to come up right?
