Well, you can come up with almost everything from a bicycle to a space shuttle. But, hey, I am looking only for 10 - that too in Enterprise IT only. Here's my list...10. Cloud ComputingSo says wiki... Cloud computing is a way of computing, via the Internet, that broadly shares computer resources instead of using software or storage on a local computer.Attempts to leverage existing resources or

No. This article is NOT about Google. Yes. I admit it. When someone says "search" the one and only search engine I think of, is Google. However, there are a bunch of search engines available out there that can do a better job for given search type / criteria. This article is about one such cool search engines I ran in to recently. Ever wondered, what Google's results would look like when searched

NO. Net Robots don't have a job as fancy as their name !Net Robot is basically a program that accesses a web page (just like a web browser) and identifies links in it. It then takes each link in the web page and does the same job recursively. This process of scanning every single page and identifying their links over and over is what is known as Web Crawling.If you are wondering, why anyone would

Virtualization is here. It is inescapable.Some say, it's the most important new force in enterprise IT since IP networks... It is the IT's answer to the never-ending cost cutting challenges being faced.Imagine a world, where you open a console and fire a query against your data warehouse / mart for a specific set of requirement and the system gives you a result back after firing the query on an

Well, we've been trying to do it since years...!This is the first reaction you will receive from your manager, if you talk about MDM - Master Data Management. Lately, MDM has become an increasingly challenging and yet necessary initiative for medium - large enterprises.In short and simple, MDM is all about having one and only version of the truth. Say, you recently purchased a desktop of 'X'

SaaS as it is often called, is basically the next generation of application hosting model.Traditionally, applications are either entirely hosted on the server OR hosted as client-server model, where some components are installed on the client machine whereas the core components are running on the servers. However these models have the following drawbacks:Initial server costCost for expert

Everyone of us who have worked with current generation data integration tools, have used the "Caching" and most of us do love it ! Change Detection and a lot of similar operations that are based on high volumes speed up by caching the data, as this reduces the Disk I/O operations.In certain cases, caching could be deadly. Consider a scenario where we receive a batch of 10K records that needs to

Log... Log... Log... I would disagree there is any better mantra for applications to be termed as "well built". Even though most of the programmers consider proper logging mechanisms as time consuming and not-worthy spending time, I believe, proper log files being generated out of the application saves a lot of time that is usually spent debugging the application at a later stage.It is estimated

The quest for a cost effective and well-performed database existed since time immemorial. While High-End databases like Teradata offer extreme scalability and performance, Cost is too High. Databases like SQL Server are very cost effective but have serious performance issues.Every time I am in a Design Review or Performance Review meeting, my attention is drawn towards the way we store the

Integration of Data has come a long way. From those good old days of "ETL" to all the way through "Real-time Data Transformation", Data Integration has been and continues to be a challenge. It's just no longer about extracting and loading data to / from databases like Oracle and SQL Server. Today - it's more. It's much more. Increased ways of doing business has consistently increased ways we
