What Is a Spatial Index?


HOME ยป Computers

In database design, an index is a data structure that takes the value of one or more columns, or fields, as input and returns the corresponding records quickly. A spatial index is an index on a column containing spatial data or, in other words, data representing the length, area and volume of lines, surfaces and other objects. Spatial data is often used in computer-aided design, map making and geographic information systems. PurposeSpatial datasets are typically large and irregularly distributed. If a query is performed on a spatial dataset without spatial indexes, every record in the dataset needs to be examined to determine if it matches the search criteria. This type of scan, known as

The Difference Between Index.html & Index.php
Computers
Index.html and Index.php are standard names for files containing Web pages. Web pages are held on Web servers in a directory structure just like the directories of a a PC. Although these two files have the same base name, the different file extension makes each unique, and so both can exist in the same directory. The file extensions indicate the languages they are written in. HTMLAll Web pages are delivered to Web browsers in a format called the Hypertext Markup Language. This is because all Web browsers are HTML readers, or viewers. They are not able to display files written in any other format, and they cannot execute program code. The only way a different format or file can be shown in

Indexed annuities are insurance policies that act like long-term savings. These policies may extend for up to 15 years or more. However, the interest credited to the policies is different from a regular fixed annuity. Indexed annuities tie the interest crediting to a stock market index. Annual Point-to-PointAnnual point-to-point, also called the "annual reset" method, uses the date at which you put money into the annuity as the starting date to track the market index you will be earning your interest from. For example, if your indexed annuity tracks the S&P 500 index, then the day you put money into the contract is the day the annuity starts tracking the S&P 500 for its gains. On the anni
