League System
A league system is a hierarchy of sports league, leagues in a sport. They are often called pyramids, due to their tendency to split into an increasing number of regional divisions further down the system. League systems of some sort are used in many sports in many countries. Overview In association football, rugby union, rugby league and Gaelic games, league systems are usually connected by the process of promotion and relegation, in which teams from a lower division who finish at the top of the standings in their league are promoted (advanced to the next level of the system) while teams who finish lowest in their division are relegated (move down to a lower division). This process can be automatic each year, or can require playoffs. In North America, league systems in the most popular sports do not use promotion or relegation. Most professional sports are divided into major professional sports leagues in the United States and Canada, major and minor leagues. Baseball and associat ...

Hierarchy
A hierarchy (from Ancient Greek, Greek: , from , 'president of sacred rites') is an arrangement of items (objects, names, values, categories, etc.) that are represented as being "above", "below", or "at the same level as" one another. Hierarchy is an important concept in a wide variety of fields, such as architecture, philosophy, design, mathematics, computer science, organizational theory, systems theory, systematic biology, and the social sciences (especially political science). A hierarchy can link entities either directly or indirectly, and either vertically or diagonally. The only direct links in a hierarchy, insofar as they are hierarchical, are to one's immediate superior or to one of one's subordinates, although a system that is largely hierarchical can also incorporate alternative hierarchies. Hierarchical links can extend "vertically" upwards or downwards via multiple links in the same direction, following a path (graph theory), path. All parts of the hierarchy that are ...

List Of Professional Sports Leagues
This is a list of professional sports leagues. A sports league is a professional body that governs the competition of its teams. They make the rules for competition and behavior and disciplines its members as necessary. This is done through a structure that varies by league. Some are made up of a board of governors that have a commissioner or president, while others are single entity organizations where the league owns the franchises and therefore does not have a board of governors. This list attempts to show those sports leagues for which all players and teams are paid to play. In other words, these players can be considered to play their chosen sport as their profession. Some leagues do not pay well enough to allow players to use them as their primary or only source of income, but because the players are paid, it is still considered professional, or semi-professional. As such, some leagues listed here may not be fully professional. Basketball Bat and ball games: Baseball ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tournament
A tournament is a competition involving at least three competitors, all participating in a sport or game. More specifically, the term may be used in either of two overlapping senses: # One or more competitions held at a single venue and concentrated into a relatively short time interval. # A competition involving a number of matches, each involving a subset of the competitors, with the overall tournament winner determined based on the combined results of these individual matches. These are common in those sports and games where each match must involve a small number of competitors: often precisely two, as in most team sports, racket sports and combat sports, many card games and board games, and many forms of competitive debating. Such tournaments allow large numbers to compete against each other in spite of the restriction on numbers in a single match. These two senses are distinct. All golf tournaments meet the first definition, but while match play tournaments meet the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
