Aggregate (data Warehouse)
An aggregate is a type of summary used in Dimensional modeling, dimensional models of data warehouses to shorten the time it takes to provide answers to typical queries on large sets of data (computing), data. The reason why aggregates can make such a dramatic increase in the performance of a data warehouse is the reduction of the number of rows to be accessed when responding to a query. Use In its simplest form, an aggregate is a simple summary table that can be derived by performing a ''Group by'' SQL query. A more common use of aggregates is to take a Dimension (data warehouse), dimension and change its granularity. When changing the granularity of the dimension the Fact (data warehouse), fact table has to be partially summarized to fit the new Data grain, grain of the new Dimension (data warehouse), dimension, thus creating new Dimension (data warehouse), dimensional and fact tables, to fit this new level of grain. Design Aggregates are sometimes referred to as pre-calcula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aggregate Fruit
A raspberry_beetle.html" ;"title="raspberry fruit (shown with a raspberry beetle">raspberry fruit (shown with a raspberry beetle larva) is an aggregate fruit, an aggregate of drupelets. image:Aquilegia vulgaris 004.JPG, The fruit of an ''Aquilegia'' flower is one fruit that forms from several ovaries of one flower, and it is an aggregate of follicles. However, because the follicles are not fused to one another, it is not considered an aggregate fruit. An aggregate fruit or etaerio () is a fruit that develops from the merger of several ovaries that were separated in a single flower. In contrast, a ''simple fruit'' develops from one ovary, and a ''multiple fruit'' develops from multiple flowers. In languages other than English, the meanings of "aggregate" and "multiple" fruit are reversed, so that "aggregate" fruits merge several flowers. The differences in meaning are due to a reversal in the terminology by John Lindley, which has been followed by most English-language authors. Not ...

Aggregate Score
There are a number of formats used in various levels of competition in sports and games to determine an overall champion. Some of the most common are the ''single elimination'', the ''best-of-'' series, the ''total points series'' more commonly known as ''on aggregate'', and the ''round-robin tournament''. Single elimination A single-elimination ("knockout") playoff pits the participants in one-game matches, with the loser being dropped from the competition. Single-elimination tournaments are often used in individual sports like tennis. In most tennis tournaments, the players are seeded against each other, and the winner of each match continues to the next round, all the way to the final. When a playoff of this type involves the top four teams, it is sometimes known as the Shaughnessy playoff system, after Frank Shaughnessy, who first developed it for the International League of minor league baseball. Variations of the Shaughnessy system also exist, such as in the promotion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Social Group
In the social sciences, a social group is defined as two or more people who interact with one another, share similar characteristics, and collectively have a sense of unity. Regardless, social groups come in a myriad of sizes and varieties. For example, a society can be viewed as a large social group. The system of behaviors and psychological processes occurring within a social group or between social groups is known as group dynamics. Definition Social cohesion approach A social group exhibits some degree of social cohesion and is more than a simple collection or aggregate of individuals, such as people waiting at a bus stop, or people waiting in a line. Characteristics shared by members of a group may include interests, values, representations, ethnic or social background, and kinship ties. Kinship ties being a social bond based on common ancestry, marriage or adoption. In a similar vein, some researchers consider the defining characteristic of a group as social ...

Tone Row
In music, a tone row or note row ( or '), also series or set, is a non-repetitive ordering of a set of pitch-classes, typically of the twelve notes in musical set theory of the chromatic scale, though both larger and smaller sets are sometimes found. History and usage Tone rows are the basis of Arnold Schoenberg's twelve-tone technique and most types of serial music. Tone rows were widely used in 20th-century contemporary music, like Dmitri Shostakovich's use of twelve-tone rows, "without dodecaphonic transformations." A tone row has been identified in the A minor prelude, BWV 889, from book II of J.S. Bach's '' The Well-Tempered Clavier'' (1742) and by the late eighteenth century it is found in works such as Mozart's C major String Quartet, K. 157 (1772), String Quartet in E-flat major, K. 428, String Quintet in G minor, K. 516 (1790), and the Symphony in G minor, K. 550 (1788). Beethoven also used the technique but, on the whole, "Mozart seems to have employed seria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aggregate (rocket Family)
The ''Aggregat'' series (German for "Aggregate") was a set of ballistic missile designs developed in 1933–1945 by a research program of Nazi Germany's Army (German Army (1935–1945), ''Heer''). Its greatest success was the A4, more commonly known as the V2 rocket, V2. A1 (1933) The A1 was the first rocket design in the ''Aggregat'' series. It was designed in 1933 by Wernher von Braun at the German Army research program at Kummersdorf headed by Colonel Dr Walter Dornberger. The A1 was the grandfather of most modern rockets. The rocket was long, in diameter, and had a takeoff weight of . The engine, designed by Arthur Rudolph, used a pressure-fed rocket propellant system burning ethanol fuel, ethanol and liquid oxygen, and produced 2.9 kilonewton, kN (660 pound-force, lbf) of thrust for 16 seconds. The LOX tank was located within the fuel tank and insulated with a fiberglass material. The rocket was stabilized by a 3 axis stabilized spacecraft, 3 axes gyroscope system ...

Construction Aggregate
Construction aggregate, or simply aggregate, is a broad category of coarse- to medium-grained particulate material used in construction. Traditionally, it includes natural materials such as sand, gravel, crushed stone. As with other types of aggregates, it is a component of composite materials, particularly concrete and asphalt. Aggregates are the most mined materials in the world,Introduction (1): What are Aggregates? « Herefordshire & Worcestershire Earth Heritage TrustIntroduction (1): What are Aggregates? « Herefordshire & Worcestershire Earth Heritage Trust, accessdate: March 23, 2017Define Aggregate at Dictionary.comaggregate accessdate: March 23, 2017 being a significant part of 6 billion tons of concrete produced per year. Aggregate serves as reinforcement to add strength to the resulting material. Due to the relatively high hydraulic conductivity as compared to most soil types, aggregates are widely used in drainage applications such as foundation and French drain ...

Aggregate (composite)
Aggregate is the component of a composite material that resists compressive stress and provides bulk to the material. For efficient filling, aggregate should be much smaller than the finished item, but have a wide variety of sizes. Aggregates are generally added to lower the amount of binders needed and to increase the strength of composite materials. Sand and gravel are used as construction aggregate with cement to make concrete and increase its mechanical strength. Aggregates make up 60-80% of the volume of concrete and 70-85% of the mass of concrete. Comparison to fiber composites ''Aggregate composites'' are easier to fabricate, and more predictable in their finished properties, than '' fiber composites''. Fiber orientation and continuity can have a large effect, but can be difficult to control and assess. Aggregate materials are generally less expensive. Mineral aggregates are found in nature and can often be used with minimal processing. Not all composite materials i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
