P\u0101rl\u016bko\u0161anas tabula, kas paz\u012bstama ar\u012b k\u0101 hash<\/a> tabula vai asociat\u012bvais mas\u012bvs ir dati<\/a> strukt\u016bra, kas glab\u0101 atsl\u0113gu un v\u0113rt\u012bbu p\u0101ru kopumu. To izmanto, lai kart\u0113tu atsl\u0113gu kopumu ar atbilsto\u0161aj\u0101m v\u0113rt\u012bb\u0101m, t\u0101d\u0113j\u0101di \u013caujot efekt\u012bvi ieg\u016bt datus, pamatojoties uz konkr\u0113to atsl\u0113gu.<\/p>\n

Atv\u0113r\u0161anas tabula sast\u0101v no div\u0101m galvenaj\u0101m da\u013c\u0101m: atsl\u0113gas un v\u0113rt\u012bbas. Atsl\u0113ga tiek izmantota datu identific\u0113\u0161anai, bet v\u0113rt\u012bba ir pa\u0161i dati. Atsl\u0113gas un v\u0113rt\u012bbas p\u0101rus glab\u0101 mas\u012bv\u0101, kur katrai atsl\u0113gai ir piesaist\u012bta atbilsto\u0161\u0101 v\u0113rt\u012bba. Atsl\u0113gas un v\u0113rt\u012bbas var b\u016bt jebkura datu tipa, piem\u0113ram, veseli skait\u013ci, virknes vai objekti.<\/p>\n

Viena no galvenaj\u0101m uzmekl\u0113\u0161anas tabulas izmanto\u0161anas priek\u0161roc\u012bb\u0101m ir t\u0101s \u0101trums un efektivit\u0101te. T\u0101 nodro\u0161ina past\u0101v\u012bgu piek\u013cuvi datiem neatkar\u012bgi no datu kopas lieluma. Tas ir t\u0101p\u0113c, ka uzmekl\u0113\u0161anas tabul\u0101 tiek izmantota hash funkcija, lai katru atsl\u0113gu atveidotu unik\u0101lam indeksam mas\u012bv\u0101, kas datu izg\u016b\u0161anu padara \u013coti \u0101tru.<\/p>\n

Uzskat\u012b\u0161anas tabulas parasti izmanto datorprogramm\u0113\u0161an\u0101 t\u0101diem uzdevumiem k\u0101 ke\u0161\u0113\u0161ana, indeks\u0113\u0161ana un mekl\u0113\u0161ana. T\u0101s tiek izmantotas ar\u012b datub\u0101z\u0113s, lai uzlabotu vaic\u0101jumu veiktsp\u0113ju, izveidojot indeksus bie\u017ei piepras\u0101majiem stabi\u0146iem.<\/p>\n

Kopum\u0101 uzmekl\u0113\u0161anas tabulas ir b\u016btiska datu strukt\u016bra datorzin\u0101tn\u0113, un t\u0101s pla\u0161i izmanto daudz\u0101s da\u017e\u0101d\u0101s lietojumprogramm\u0101s.
