An index is an indirect shortcut derived from and pointing into a greater volume of values, data, information or knowledge. Index may refer to:
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.
The symbol ☞ is a punctuation mark, called an index, manicule (from the Latin root manus for "hand" and manicula for "little hand") or fist. Other names for the symbol include printer's fist, bishop's fist, digit, mutton-fist, hand, hand director, pointer, and pointing hand.
The symbol originates in scribal tradition of the medieval and Renaissance period, appearing in the margin of manuscripts to mark corrections or notes.
Manicules are first known to appear in the 12th century in handwritten manuscripts in Spain, and became common in the 14th and 15th centuries in Italy with some very elaborate with shading and artful cuffs. Some were playful and elaborate, but others were as simple as "two squiggly strokes suggesting the barest sketch of a pointing hand" and thus quick to draw.
After the popularization of the printing press starting in the 1450s, the handwritten version continued in handwritten form as a means to annotate printed documents. Early printers using a type representing the manicule included Mathias Huss and Johannes Schabeler in Lyons in their 1484 edition of Paulus Florentinus' Breviarum totius juris canonici.
Kraków (Polish pronunciation: [ˈkrakuf] listen ), also Cracow or Krakow (US English /ˈkrɑːkaʊ/, UK English /ˈkrækɒv/), is the second largest and one of the oldest cities in Poland. Situated on the Vistula River (Polish: Wisła) in the Lesser Poland region, the city dates back to the 7th century. Kraków has traditionally been one of the leading centres of Polish academic, cultural, and artistic life and is one of Poland's most important economic hubs. It was the capital of the Crown of the Kingdom of Poland from 1038 to 1569; the Polish–Lithuanian Commonwealth from 1569 to 1596; the Free City of Kraków from 1815 to 1846; the Grand Duchy of Cracow from 1846 to 1918; and Kraków Voivodeship from the 14th century to 1998. It has been the capital of Lesser Poland Voivodeship since 1999.
The city has grown from a Stone Age settlement to Poland's second most important city. It began as a hamlet on Wawel Hill and was already being reported as a busy trading centre of Slavonic Europe in 965. With the establishment of new universities and cultural venues at the emergence of the Second Polish Republic in 1918 and throughout the 20th century, Kraków reaffirmed its role as a major national academic and artistic centre. The city has a population of approximately 760,000, with approximately 8 million additional people living within a 100 km (62 mi) radius of its main square.
Kraków is a Polish parliamentary constituency that is coterminous with the Lesser Poland Voivodeship. It elects thirteen members of the Sejm and four members of the Senate. It is the only constituency that covers different areas for elections to the Sejm to elections to the Senate, as it includes the Sejm constituency of Chrzanów for elections to the Senate.
The district has the number '13' for elections to the Sejm and '12' for elections to the Senate, and is named after the city of Kraków. For elections to the Sejm, it includes the counties of Brzeg, Kraków, Miechów, and Olkusz and the city county of Kraków. For elections to the Senate, it also includes the counties of Chrzanów, Myślenice, Oświęcim, Sucha, and Wadowice.
