Read/Write operation on indexed and non-indexed table

Thursday, February 21st, 2008

Today, I got a question related to database indexes. It was a tricky question which is very easy to say in words but was very difficult to say in exact or approximately figures.The question is:

if we have one million records in the table and we want to perform Read/Write operations, but in different cases. Which are:

Case 1: We have indexed table.
Case 2: We have non-indexed table.

Query:
If one query take 1 unit (time) to read from indexed table. Then
1. How much it will take from non-indexed table to read?
2. How much to write in indexed table?
3. how much to write in non-indexed table?

The answer may be approximately not exactly.

Unit may be any time: for example it may be 1 micro second.

Now the matrix is:

Indexed Table Non-Indexed Table
Read Operation 1 Unit ?
Write Operation ? ?

So, What do u say? any idea for this query?

PS: You may consider different Data base servers like SQL Server, MySql, Oracle etc. Also please cosider the Web and desktop technologies iff there is any difference. Otherwise this is general query.

History of ROZEE.PK

History of ROZEE.PK is very interesting. CEO of Naseeb Networks, Inc. Mr. Monis Rahman said, “ROZEE was started mainly out of a need to hire people for their own office in Lahore. When I moved back to Pakistan four years ago. It was difficult to find good people. Newspaper ads were expensive and inefficient. So, we launched a job site to help us find talen. ROZEE is still a free site where any employer can advertise job openings. The goal is to connect talent with opportunity.”

Virus: Olympic Torch Hoax [Sophos] - “Invitation”

Tuesday, December 11th, 2007

If you receive a mail called “invitation”, though sent by a friend, do not open it and shut down your computer immediately.

The Olympic Torch Hoax is being spread through email. It has been reported that the following text of the hoax may differ slightly in the various messages going around. This hoax email includes the following warning: Subject: Invitation. This virus does not exist.

You should be alert during the next days:
Do not open any message with an attached filed called “Invitation” regardless of who sent it . It is a virus that opens an Olympic Torch which “burns” the whole hard disc C of your computer. This virus will be received from someone who has your e-mail address in his/her contact list, that is why you should send this e-mail to all your contacts. It is better to receive this message 25 times than to receive the virus and open it.

If you receive a mail called “invitation”, though sent by a friend, do not open it and shut down your computer immediately.This is the worst virus announced by CNN, it has been classified by Microsoft as the most destructive virus ever.

This virus was discovered by McAfee yesterday, and there is no repair yet for this kind of virus.

This virus simply destroys the Zero Sector of the Hard Disc, where the vital information is kept.

Top Ten Mistakes in Web Design

Tuesday, November 21st, 2006

1. Using Frames

Splitting a page into frames is very confusing for users since frames break the fundamental user model of the web page. All of a sudden, you cannot bookmark the current page and return to it (the bookmark points to another version of the frameset), URLs stop working, and printouts become difficult. Even worse, the predictability of user actions goes out the door: who knows what information will appear where when you click on a link?

2. Gratuitous Use of Bleeding-Edge Technology

Don’t try to attract users to your site by bragging about use of the latest web technology. You may attract a few nerds, but mainstream users will care more about useful content and your ability to offer good customer service. Using the latest and greatest before it is even out of beta is a sure way to discourage users: if their system crashes while visiting your site, you can bet that many of them will not be back. Unless you are in the business of selling Internet products or services, it is better to wait until some experience has been gained with respect to the appropriate ways of using new techniques. When desktop publishing was young, people put twenty fonts in their documents: let’s avoid similar design bloat on the Web.

As an example: Use VRML if you actually have information that maps naturally onto a three-dimensional space (e.g., architectural design, shoot-them-up games, surgery planning). Don’t use VRML if your data is N-dimensional since it is usually better to produce 2-dimensional overviews that fit with the actual display and input hardware available to the user.

3. Scrolling Text, Marquees, and Constantly Running Animations

Never include page elements that move incessantly. Moving images have an overpowering effect on the human peripheral vision. A web page should not emulate Times Square in New York City in its constant attack on the human senses: give your user some peace and quiet to actually read the text!

Of course, < blink > is simply evil. Enough said.

4. Complex URLs

Even though machine-level addressing like the URL should never have been exposed in the user interface, it is there and we have found that users actually try to decode the URLs of pages to infer the structure of web sites. Users do this because of the horrifying lack of support for navigation and sense of location in current web browsers. Thus, a URL should contain human-readable directory and file names that reflect the nature of the information space.

Also, users sometimes need to type in a URL, so try to minimize the risk of typos by using short names with all lower-case characters and no special characters (many people don’t know how to type a ~).

5. Orphan Pages

Make sure that all pages include a clear indication of what web site they belong to since users may access pages directly without coming in through your home page. For the same reason, every page should have a link up to your home page as well as some indication of where they fit within the structure of your information space.

6. Long Scrolling Pages

Only 10% of users scroll beyond the information that is visible on the screen when a page comes up. All critical content and navigation options should be on the top part of the page.

Note added December 1997: More recent studies show that users are more willing to scroll now than they were in the early years of the Web. I still recommend minimizing scrolling on navigation pages, but it is no longer an absolute ban.

7. Lack of Navigation Support

Don’t assume that users know as much about your site as you do. They always have difficulty finding information, so they need support in the form of a strong sense of structure and place. Start your design with a good understanding of the structure of the information space and communicate this structure explicitly to the user. Provide a site map and let users know where they are and where they can go. Also, you will need a good search feature since even the best navigation support will never be enough.

8. Non-Standard Link Colors

Links to pages that have not been seen by the user are blue; links to previously seen pages are purple or red. Don’t mess with these colors since the ability to understand what links have been followed is one of the few navigational aides that are standard in most web browsers. Consistency is a key to teaching users what the link colors mean.

9. Outdated Information

Budget to hire a web gardener as part of your team. You need somebody to root out the weeds and replant the flowers as the website changes but most people would rather spend their time creating new content than on maintenance. In practice, maintenance is a cheap way of enhancing the content on your website since many old pages keep their relevance and should be linked into the new pages. Of course, some pages are better off being removed completely from the server after their expiration date.

10. Overly Long Download Times

I am placing this issue last because most people already know about it; not because it is the least important. Traditional human factors guidelines indicate 10 seconds as the maximum response time before users lose interest. On the web, users have been trained to endure so much suffering that it may be acceptable to increase this limit to 15 seconds for a few pages.

Even websites with high-end users need to consider download times: many B2B customers access websites from home computers in the evening because they are too busy to surf the Web during working hours.
