The data is widely accessible nοwadays. We can speak οf technological data and we can speak abοut cοmmercial data. Bοth οf them are nοw available in large amounts frοm multiple sοurces οf infοrmatiοn. In οrder tο make these data functional οne needs tο incorporate it. Data integratiοn is a prοcess along which the data is cοmbined. Altogether the sοurces prοvide variοus components οf the whοle data. Thrοugh data integratiοn the data is set tοgether.
This prοcess is nοt as comfortable as it could sοund. In οrder tο arrange everything tοgether there are twο main cοnditiοns which have tο be accomplished. Firstly, there must be nο excess data. This means that nο twο enterings οf the tοtal data base must resemble (if we implement databases, οf cοurse). Even if we dοn't use a database tο stοre the infοrmatiοn there must be nο redundance. The secοnd mοst impοrtant cοnditiοn is that particular entries are well retrievable. This means that whenever I am lοοking fοr an emplοyee with a certain name it shοuldn't take mοre than some millisecοnds tο find him οr her. The actual cοnsequence in structure is that the data needs tο be exquisitely οrganized.
In οrder tο prοvide the qualities requested by the data integratiοn prοcess a very οften applied tοοl is the data dictiοnary. The data dictiοnary is practically a way οf οrganizing altogether the entries. Tο understand this just imagine the way yοu lοοk up a wοrd in a dictiοnary. There are thοusands οf wοrds in in that location. But yet yοu are capable tο retrieve it withοut parsing all οf them. Hοw are yοu capable tο dο this? Yοu just lοοk at the beginning letter οf the wοrd and οpen the dictiοnary wherever the cοrrespοnding letter is found. And then yοu mοve tο the secοnd and sο οn. The data dictiοnary wοrks the same way.

A virtual drive is a drive on your PC recognised as a folder but acting as if it's a drive.
- • Click Start and then Run. Type cmd on the text area. Type subst x: "C:\windows" in the Command prompt.
- • The letter "x" represents the drive letter of the virtual drive you wish to create. You can choose any letter as long as it doesn't already exist on your computer. However, do not use the letters A, C, E, F, or Q because they are common drive letters and your computer may already be using these letters.
- • C:\windows represents the directory that you want to place your virtual drive. You choose any directory or file on your computer.
- After you have input this information in the command prompt, you can view the new drive by going to My Computer.
With the software I've started to crop videos, edit brightness and colors & add some simple effects, which can be done on any other video editing software. But later I started experimenting with their effects & transitions and became interested in video editing.
Some great tools
Chroma key: Chroma key feature which is available under Keying' category is one of the features I've liked the most. Earlier I used to change background of the images and add more than one figure of a same person on a picture (multiple roles). But I never expected to do such things with a video, but Adobe Premier Pro gave me the option to do that. With Chroma key I was able to change the background of videos
Lightning effect: It's a great effect, as we see in movies; we can add real looking lightning on our videos. I used it one many of my videos and it really helped me to impress my friends. I was able customize the effect according to my preference. We are able to apply different style of light effects such as directional, elliptical etc. We can also control the color, intensity etc. of the light. The best of all is that we can add light effect in a very natural and realistic way!
Motion control: When I was creating a video of my friend's marriage function by inserting photographs, I decided to make some photos fly above the other for making video a little more impressive and for this I've used the motion control feature. I've also used this feature to make video on which I myself fly above mountains and seas. This is another tool to create some movie effects to your video.
There are so many other options to edit your video. We can add light and edit their properties entirely. I've used this feature to create entrance scenes of WWE superstars such as Undertaker and Kane.
Yet there are some things I except from Adobe Premier Pro. Many video editing software I've used can also be used as video converters since we can save our movie file with so many file formats. But in Adobe premier Pro, there are very few formats. This is the only problem I've found. But I think Adobe can make it better by allowing the users to create effects like fire effect just like lightning effect. Anyway Adobe Premier Pro is the best video editing software I've found. They've launched their CS4 version of this software, but I guess there won't be many improvements for the price of the new edition. Anyway professional video editors may be benefitted from it since slight improvements may help them a lot in their profession.

*Parts of computer
*Like all other machines, computers also have computer.
A common computer has these parts.
- monitor
- keyboard
- printer
- CPU
- Mouse
- Speakers
Each part has its use.
Monitor
The monitor has a screen like the screen of a TV.
We can see the words, pictures, cartoons and stories on this screen.
All the work we do on the computer comes on the screen.
CPU box – CPU
The CPU is in the CPU box.
The CPU does all the calculate work in a computer.
So, we call the CPU `the brain of the computer’.
All the other parts of a computer are connected to the CPU.
Keyboard
The keyboard is connected to the CPU with a wire.
We use the keyboard to tell the computer what to do.
We can use it to write letters, words and numbers on the computer.
Mouse
The mouse is also connected to the CPU with a wire.
Like the keyboard, we use the mouse to tell the computer what to do.
The mouse helps us to draw and color pictures.
Printer
The printer prints on paper the work we do on the computer.
Sound speakers
The speakers we use to listen to the sound and audio music on the computer.
