Database index

A database index is a data structure that improves the speed of data retrieval operations on a database table at the cost of additional writes and storage space to maintain the index data structure. Indexes are used to quickly locate data without having to search every row in a database table every time a database table is accessed. Indexes can be created using one or more columns of a database table, providing the basis for both rapid random lookups and efficient access of ordered records.

An index is a copy of select columns of data from a table that can be searched very efficiently that also includes a low-level disk block address or direct link to the complete row of data it was copied from. Some databases extend the power of indexing by letting developers create indices on functions or expressions. For example, an index could be created on upper(last_name), which would only store the upper case versions of the last_name field in the index. Another option sometimes supported is the use of partial indices, where index entries are created only for those records that satisfy some conditional expression. A further aspect of flexibility is to permit indexing on user-defined functions, as well as expressions formed from an assortment of built-in functions.

Index (statistics)

In statistics and research design, an index is a composite statistic – a measure of changes in a representative group of individual data points, or in other words, a compound measure that aggregates multiple indicators. Indexes summarize and rank specific observations.

Much data in the field of social sciences is represented in various indices such as Gender Gap Index, Human Development Index or the Dow Jones Industrial Average.

Item in indexes are usually weighted equally, unless there are some reasons against it (for example, if two items reflect essentially the same aspect of a variable, they could have a weight of 0.5 each).

Constructing the items involves four steps. First, items should be selected based on their face validity, unidimensionality, the degree of specificity in which a dimension is to be measured, and their amount of variance. Items should be empirically related to one another, which leads to the second step of examining their multivariate relationships. Third, indexes scores are designed, which involves determining their score ranges and weights for the items. Finally, indexes should be validateds, which involves testing whether they can predict indicators related to the measured variable not used in their construction.

Style (Orbital song)

"Style" is a 1999 single by the electronica duo Orbital. It was their fourth consecutive single, and fifth overall, to reach the top 20 of the UK singles chart, peaking at number 13.

The track takes its name from the analogue electronic musical instrument, the stylophone, which is used extensively on the track. The main version includes a sample of "Oh L'amour" performed by Dollar, while the "Bigpipe Style" version (which features the main riff played on bagpipes) samples Suzi Quatro's hit "Devil Gate Drive". Orbital's request to use a sample from a Rolf Harris stylophone demonstration disc was turned down. The other versions are "Old Style", a more club-oriented dance mix; and "New Style", a retro-styled version with live bass by Andy James.

All of the mixes are by Orbital themselves; the duo had wanted Stereolab to remix the track, but the latter group were on tour at the time and unavailable, so the "New Style" mix is Orbital's own version of a Stereolab-type mix.
