Indexing, The Power Of Information Technology By Dylon Floppours At Isnare.com Ezine Articles

Information technology is built around the idea of least expensive way to have that ability to keep a large amount of information at the tips of your fingers allowing searches that give you valuable information quickly—the answer is indexing. You see quickly is the operative word in this sentence and defines expensive. That is, the most expensive query is the one that takes the most time. Likewise least expense means least time. Breaking it down even further what is taking time?

Well time in the information technology world is linked directly to the number of computations that it takes to give you the desired output. Simply put a search that requires that the computer scan each object or row of objects in a database table to several columns is going to take more computations and therefore more time (which is the same as expense) than a search that can through thoughtful structure of the database automatically select out the desired information without having to scan the whole databases. This structure is what we are referring to when we talk of indexing or indexes.

Indexes are simply subsets of tables. Where a table may have ten columns or types of input for each row and thousands upon thousands of rows, an index is a selection of maybe two to three columns of that information. This allows the computer to select out the indexes that are not applicable to the search query first and then search row by row for the desired output instantly limiting the number of scans that it must perform. This may not seem like a huge deal with the speed at which a computer can scan a single row but we are talking about huge databases of information and thousands of necessary searches of that information per hour. Indexing therefore becomes incredibly powerful.

The applications for this are many but I want to focus quickly on one that is important to me in the world of internet marketing. You see the key to internet marketing is the traffic that you can get to your page that is interested in buying the product that you are pushing. Traffic can be gotten in a number of ways, maybe the most effective of which is to simply have the largest presence possible. That is the finest screen that will get literally every person that may have an interest in your product to see your page. This often requires thousands of pages per product. When you are marketing thousands of products the numbers start to add up. It is critical that you keep all of this information organized so that you can track progress on the sites and maximize your potential in each market that you are in. In short indexing is the only way to accomplish this huge and hugely important task.
