In economics the indexing is he procedure by which the modality of keeping the purchase value constant over time in every transaction is applied, compensating it directly or indirectly.
Procedure that proposes that an asset or salary, among others, subscribed in the long term, is not devalued by the costs of living that increase
It is generally applied at instances of the correction of the prices of certain consumer products, wages, interest rates, among others, with the mission of balancing them and bringing them closer to the general rise in prices. The indexation to be applied will be the result of the measurement of an index, such as the cost of living, or failing that, the price of gold, or the devaluation of the currency.
Basically it is a system that is used to compensate for the losses in value that the long-term subscribed obligations may suffer, such is the case of loans that are usually taken by the state, debts, salaries, among others, and that are They originate from the devaluation of the currency or from a significant inflationary process.
Then, indexation implies the setting of an index, such as the Consumer Price Index or CPI, the value of a good or a service, which will be used as a reference to determine for sure the performance or evolution that have this or that element.
With an example we will see it clearly, if, for example, the CPI of a calendar year increases by a certain percentage, the salaries of the previous year must be increased by that same percentage.
Because of course, otherwise people will be won in this case by inflation and their purchasing power will be reduced if the salary is not updated in that order.
Indexing is also widely applied in matters of interest, so when indexing the interest rate it will imply varying the percentage equivalent to the variation of another that will be taken as a reference.
The mission of this procedure is to balance and bring wages closer to the rise in prices of consumer products or to do the same with the interest rate set for a loan, that is, if there has been a significant jump in this sense, the agreed rate is not absolutely obsolete.
On the other hand, it is very common that indexation is applied to contracts, such as the rental of a home.
The usual thing is that this type of contracts are celebrated for 24 months, then, a year an indexation is established in the value of the rent based on indicators such as the CPI; However, in highly inflationary times it is customary for indexing to take place every six months.
Computing: process by which a search engine crawls a site and at the same time incorporates the URLS into its database
On the other hand, in the field of computing, the indexing will be called process by which the search engine crawls the site in question and in turn incorporates the content of those URLs into its database, that is, information is registered in order to build an index. This procedure is very important for web pages since it is what allows the page to appear in some of the most important search engines; a page that has not been indexed as it should will not appear among the results of a search.
It is important to bear in mind that search engines do not index everything they go through, but will only index when something they consider appropriate appears.
In order to help indexing, it is advisable to receive many visits, since the more passes there will be more possibilities of indexing. For this frequency of passage to increase, it will be necessary to get incoming links to our website and update it very often.
Search engines like Google or Yahoo, specialized in searching for information on the Internet, constantly explore the web, creating an index of each of the pages approached, as well as an index of its content. So when someone performs a search, the search engine goes directly to the index to locate the requested information, resulting in accurate and very fast information, if the index does not exist, the search engine should scan all the content of the web page in such a way. individual every time someone starts a search, and obviously considering the enormous amount of material uploaded to the internet, the result would be very, very slow and would also demand a power in the computers that is really impossible to maintain for many.
