The term web2.0 was originally presented by O’Reilly Media (A well known media company publishing books and websites on various computer technology topics). It’s a term that refers to a new generation of websites (social networking websites, wiki-based websites etc). These websites take advantage of web application technologies and give web users the ability to collaborate and share their experiences, views, opinions and interests while they surf the web.
The web2.0 is a revolutionary phenomenon. Let’s talk about the most basic characteristics of the websites using the web2.0 concept:

There are three broad ways to turn your web site into a place where your customers can buy your products and services and pay you money for them.
The first is to get a merchant account and set up a professional private shopping cart. This makes sense if you also do consumer shows where you can take credit card orders, or otherwise have reason to take credit card orders in person. However, if you’re predominantly a web-based business, it’s probably overkill. It requires installing somewhat arcane software, it requires going through and configuring said software, and getting a signed security certificate, and the list of things that can go wrong (without you being aware of them¡) is long and somewhat scary.

Pessimistic and Optimistic Concurrency In a multi-user environment, there are two models for updating data in a database: optimistic concurrency and pessimistic concurrency.
Pessimistic concurrency involves locking the data at the database when you read it. You essentially lock the database record and don’t allow anyone to touch it until you are done modifying and saving it back to the database. Here you have 100% assurance that nobody
will modify the record and while you check it have it checked out, out. Another person will have to wait until you have made the your changes.
By default, SQL Server controls lock escalation, but you can control it yourself by using lock optimizer hints. Here are some
lock escalation hints you may want to consider: Read the rest of this entry »

Are you struggling to find what you are looking for online? Does it seem to you that no matter you do you can never find exactly what you are searching?

1. Never use only one search engine. Often the results in one search engine will be different from those in another. You can even try using a multiple search engines site such at dogpile.com or metacrawler.com. Another less used but useful search engine is clusty.com. This search engine has a different way of processing results thus often giving out different sites than the others. Read the rest of this entry »

There is a common “patchwork” philosophy in IT departments throughout the world that gives the idea that altering, changing, and fixing poorly designed databases is how you correct the problems – as opposed to starting from the ground-up and re-working a system.
While Relational Database Design gets thrown out the window, a terrible side effect of this patchwork idea takes hold inside of most of these organizations. Databases – whether Microsoft Access, SQL Server, Oracle, or MySQL – have a tendency to be amazing thieves when poorly designed to begin with.
If you’re faced with a project that’s designed poorly, but could be “patched up” to do what you need to, consider the following: Read the rest of this entry »

If you want to get paid to write, the smartest thing to begin with is to create a list of your interests. You are bound to create well-informed, interesting posts, as long as you have a true inclination or at least a true passion for the topic on which you are writing.
You can start with baby steps – for example, your lifestyle. If you are in college, you can get paid to blog about solutions to problems other people of your age are facing, as well as personal impressions about the environment in which you are living. You can include a lot of useful information, and you will be amazed at the number of people who will find your tips quite useful. Read the rest of this entry »
