数据库术语简述
术语： 关系模式：是一种用于描述二维表格结构的表示方式，由关系模式和与该关系模式名相关联的属性名表组成。其形式为：关系模式名（属性名1，属性名2，…，属性名n）。Create table xxoo (xxx,xxxx,xx,,x) 关系模型：是一种用二维表格结构表示数据及数据之间联系的数据模型。 候选键：如果一个属性集能唯一地标识一个关系中的元组而又不含有多余属性，则称该属性值为该关系的候选键。 主键：是指当某个关系模式有多个候选键时，被用户选用的那个候选键。 外键：如果关系模式R1中的某属性集是另一个关系模式R2的主键，则该属性在关系模式R1中称为外键。 概念模式：是对数据库中全部数据的整体逻辑结构的描述，体现了全局、整体的数据观点，所以称为数据库的整体逻辑结构。 外模式：是表达用户使用观点和用到的那部分数据的逻辑描述，体现了应用程序员对数据库的数据观点。 内模式：是数据库在物理结构和物理存储方面的描述，规定了数据的内部记录类型、记录建起技术、文件的组织方式和数据控制方面的细节等。 关系的目或度：关系中的属性个数。 关系的基数：关系中元组的个数。 笛卡儿积运算：设关系R和S的目数分别为r和s，R和S的笛卡儿积是一个r+s 目的元组集合，每个元组的前r个分量来自R中的的一个元组，后s个分量来自S中的一个元组。
j2...jk，j1中取出序号为R的顺序从关系j1,j2.....jk：投影运算是按照投影运算．的K列。并除去结果中的重复元素构成一个以j1，j2...jk为顺序的K目关系。选择运算：从关系R中挑选出满足公式F的那些元组。 联接运算：从关系R和S的笛卡儿积中选取属性值满足某一比较运算操作的元组。 自然联接运算：从关系R和S的笛卡尔积中选取公共属性值相等的元组，并去除重复的属性。 聚合函数：能够根据查询结果的记录集或根据查询结果的记录集中某列值的特点返回一个汇总信息的函数。 分组查询：在SQL语言中，把元组按某个或某些列上相同的值分组，然后再对各组进行相应操作的查询方式称为分组查询。 多元查询：SQL语言允许用户在同一查询语句中从两个或多个表中查询数据，即在两个或多个表的联接运算的基础上，再从其联接结果中选取满足查询条件的元组，一般称为二元查询或多元查询。 视图：也称用户视图或外模式，反映了数据库的局部逻辑结构，是数据库应用系统中各不同用户看到和使用的数据库。 1NF:在一个关系模式R中，如果R的每一个属性的值域中的值都是不可再分的最小数据单位，则称R为第一范式，记为1NF。 2NF:如果一个关系模式R属于1NF，并且它的每一个非主属性都完全依赖于它的每一个候选键，则称R为第二范式，记为2NF。 3NF:如果一个关系模式R属于1NF，并且R的任何一个非主属性都不传递依赖于它的任何一个候选键，则称R为第三范式，记为3NF。
历史上最豪放大气荡气回肠的10首诗词
历史上最豪放大气荡气回肠的10首诗词 大风歌 刘邦 大风起兮云飞扬， 威加海内兮归故乡。 安得猛士兮守四方！ 观沧海 曹操 东临碣石，以观沧海。 水何澹澹，山岛竦峙。 树木丛生，百草丰茂。 秋风萧瑟，洪波涌起。 日月之行，若出其中； 星汉灿烂，若出其里。 幸甚至哉！歌以咏志。 将进酒 李白 君不见黄河之水天上来，奔流到海不复回。 君不见高堂明镜悲白发，朝如青丝暮成雪。 人生得意须尽欢，莫使金樽空对月。 天生我材必有用，千金散尽还复来。 烹羊宰牛且为乐，会须一饮三百杯。 岑夫子，丹丘生，将进酒君莫停。 与君歌一曲，请君为我侧耳听。 钟鼓馔玉不足贵，但愿长醉不愿醒。 古来圣贤皆寂寞，惟有饮者留其名。 陈王昔时宴平乐，斗酒十千恣欢谑。 主人何为言少钱，径须沽取对君酌。 五花马，千金裘， 呼儿将出换美酒，与尔同销万古愁。 永遇乐·京口北固亭怀古 辛弃疾 千古江山，英雄无觅，孙仲谋处。 舞榭歌台，风流总被，雨打风吹去。 斜阳草树，寻常巷陌，人道寄奴曾住。 想当年，金戈铁马，气吞万里如虎。 元嘉草草，封狼居胥，赢得仓皇北顾。 四十三年，望中犹记，烽火扬州路。 可堪回首，佛狸祠下，一片神鸦社鼓！ 凭谁问，廉颇老矣，尚能饭否？
满江红 岳飞 怒发冲冠，凭栏处，潇潇雨歇。 抬望眼，仰天长啸，壮怀激烈。 三十功名尘与土，八千里路云和月。 莫等闲，白了少年头，空悲切！ 靖康耻，犹未雪。臣子恨，何时灭？ 驾长车，踏破贺兰山缺！ 壮志饥餐胡虏肉，笑谈渴饮匈奴血。 待从头收拾旧山河，朝天阙！ 夏日绝句 李清照 生当做人杰，死亦为鬼雄。 至今思项羽，不肯过江东。 登幽州台歌 陈子昂 前不见古人， 后不见来者。 念天地之悠悠， 独怆然而泣下！ 望岳 杜甫 岱宗夫如何？齐鲁青未了。 造化钟神秀，阴阳割昏晓。 荡胸生层云，决眦入归鸟。 会当凌绝顶，一览众山小。 念奴娇·赤壁怀古 苏轼 大江东去，浪淘尽，千古风流人物。 故垒西边，人道是，三国周郎赤壁。 乱石穿空，惊涛拍岸，卷起千堆雪。 江山如画，一时多少豪杰。 遥想公瑾当年，小乔初嫁了，雄姿英发。羽扇纶巾，谈笑间、樯虏灰飞烟灭。 故国神游，多情应笑我，早生华发。 人生如梦，一尊还酹江月。 沁园春·雪 毛泽东 北国风光，千里冰封，万里雪飘。
