Dimension (data warehouse)
A dimension is a structure that categorizes facts and measures in order to enable users to answer business questions. Commonly used dimensions are people, products, place and time.
In a data warehouse, dimensions provide structured labeling information to otherwise unordered numeric measures. The dimension is a data set composed of individual, non-overlapping data elements. The primary functions of dimensions are threefold: to provide filtering, grouping and labelling.
These functions are often described as "slice and dice". Slicing refers to filtering data. Dicing refers to grouping data. A common data warehouse example involves sales as the measure, with customer and product as dimensions. In each sale a customer buys a product. The data can be sliced by removing all customers except for a group under study, and then diced by grouping by product.
A dimensional data element is similar to a categorical variable in statistics.
Typically dimensions in a data warehouse are organized internally into one or more hierarchies. "Date" is a common dimension, with several possible hierarchies:
Dimension (song)
"Dimension" is a song by Australian hard rock band Wolfmother, featured on their 2005 debut studio album Wolfmother. Written by band members Andrew Stockdale, Chris Ross and Myles Heskett, it was released as the second single from the album in Europe (and the third single overall) on 17 April 2006, charting at number 49 on the UK Singles Chart.
Music video
Directed by The Malloys, the music video for "Dimension" was first aired in the week of 13 February 2006. Prior to this, the video was featured on the 2006 extended play (EP) Dimensions.
Critical reception
In a review of Wolfmother for Blender, writer Jonah Weiner identified "Dimension" as an example of the band "at [their] hardest", describing it as an "acid anthem".NME reviewer James Jam described the song as "a throb of gonzo metal not unlike Black Sabbath playing Motown".

Krull dimension
In commutative algebra, the Krull dimension of a commutative ring R, named after Wolfgang Krull, is the supremum of the lengths of all chains of prime ideals. The Krull dimension need not be finite even for a Noetherian ring. More generally the Krull dimension can be defined for modules over possibly non-commutative rings as the deviation of the poset of submodules.
The Krull dimension has been introduced to provide an algebraic definition of the dimension of an algebraic variety: the dimension of the affine variety defined by an ideal I in a polynomial ring R is the Krull dimension of R/I.
A field k has Krull dimension 0; more generally, k[x1, ..., xn] has Krull dimension n. A principal ideal domain that is not a field has Krull dimension 1. A local ring has Krull dimension 0 if and only if every element of its maximal ideal is nilpotent.
Explanation
We say that a chain of prime ideals of the form
has length n. That is, the length is the number of strict inclusions, not the number of primes; these differ by 1. We define the Krull dimension of 
to be the supremum of the lengths of all chains of prime ideals in .
Verano (surname)
Verano is a surname of Basque origin. as a word it means "summer" in the Spanish language but as a family name in the Basque language is "a habitational name from a town in Biscay province, Basque Country in Spain", and usually applies to the descendants of the Verano family, an old basque noble family originally from Biscay province in Basque Country. It's also connected to two important Italian cities, Camerino and Ferrara, The surname Verano has been found in Camerino from as early as the 13th-16th centuries, first with the title of Vicars of the Holy See. The term Verano may have originated from the Basque "Berano", a name which is popular and common among the residents of those who lived in a town within Biscay Country. A bishop has even been cited from there in 1482. The surname Verano is distributed between Verano's family in some countries such Spain (The former Spanish colonies) in the Philippines where substantial numbers of Basques emigrated to, including United States, France, Italy, Malta, and Mexico. In the United States of America, one of the first Veranos to be recorded on fresh immigration records were from Italy and Hawaii. However since they possessed Italian and Spanish names, it can be concluded that they were descendants of those Spaniards or Europeans who landed on the shores Oceania when there was Colonialism in the islands. There are about 9,102 Documents about Verano Ancestry, 7,223 Birth, Marriage and Deaths and 665 Immigration Records in the USA.
