EMBARKO源于1886年，是制造羊绒与珍稀纱线、面料的的品牌，2017年为拓展高定羊绒定制服务，在中国同样注册了“EMBARKO”品牌，中文意译“启程”，由中国青岛公司授权代理销售。EMBARKO以制造高品质的纱线与面料为荣，而一切从收购稀有的原材料开始。譬如品牌选用的羊绒，都是在每年春天，集结中国北部与蒙古的游牧民族，将他们饲养的羊群集中收割的。在这个大规模制造与快时尚横行的年代，没有织物比羊绒更能投射出奢华的精粹了。随着人们对这种材料的热爱与需求与日俱增，品质分级、生产方法与材料原产地也越发受到关注。英国在羊绒制造与品质维持方面始终居于前列，受到行业人士与羊绒穿戴者们的信赖。对穿上我们的任何一件制品，在其擦过皮肤的瞬间，您就会即刻知晓其非凡之处；而EMBARKO更擅长将羊绒打造得如此时尚的国度了，这项工作需要密集的劳动力：每头羊都经手工梳理而非机器修剪，再对羊毛进行分级，以确保只有最柔软的纤维被送到公司位于英国苏格兰地区生产工厂。EMBARKO愿以“高品质羊绒制品”服务于从事定制服务——您们！

embark on sth/doing sth;类似于commence on这个词组start to do sth,也是开始做某事~~只是on/to 后面接的词语不一样而已。on 后加名词与现在分词to do后面加名词

embark on 有开始的意思……

board：上到车上，船上，飞机上等多种运输工具，多指人！embark：多指装载到船上，多指货物！

乘船

disembark的意思是下船，下飞机，下火车 embark的意思是上船；上飞机

embark on sth/doing sth;类似于commence on这个词组start to do sth,也是开始做某事~~只是on/to 后面接的词语不一样而已。on 后加名词与现在分词 to do后面加名词

翻译如下embark是上船的意思。可以混合记忆。em发音类似:按门，bark是吠叫的意思。连在一起就是按气门就叫。船开之前都会长按一声汽笛，这样就把embark和登船联系在一起了。

可以，但条件是必须符合kiri2的程序模式，这导致很多游戏都需要kiri2的补丁才能运行。所以不建议直接拷贝pc游戏玩，最好先到kirikiroid2吧去看看哪些能玩，并去下载下补丁。

楼上的说的很对，还有一种方法，只要修改一个配置文件即可：vi /etc/security/limits.d/90-nproc.conf把 * soft nproc 1024 这一行，在开头加#号注释掉，如果不注释，普通用户可以开启的进程就被限制为1024个。这个配置文件是RHEL6新增的，如果这个配置文件不修改，/etc/security/limits.conf中的配置就不会生效。也可以使用下面命令快速修改：sed -i "s/^*/#*/g" /etc/security/limits.d/90-nproc.conf

这个非凡的人去了一个小木屋学校，直到他12岁。他的正规教育就这样结束了。尽管有这一荣誉学位(Xford大学和Yalc(虚无主义)他是史上最老名的圈默作家。他还为美国小说带来了现实主义和西方地方色彩。他通过写文章、短篇小说和书籍赚了几百万美元。他的真名是塞缪尔·朗霍恩·克莱门斯，但他以马克·吐温闻名于世。1835年，马克·吐温出生在密苏里州密西西比河附近的一个小村庄。当时，安德鲁·杰克逊是这个国家的总统。亚伯拉罕·林肯还是伊利诺斯州一个年轻的农场工人。第一条铁路是在七年前建成的。工业革命就在眼前。美国繁荣的经济崩溃，被称为1837年的恐慌，仍然摆在前面。这也是文学时期，后来被称为“新英格兰文艺复兴马克·吐温不是一个健康的婴儿，事实上，他活不过第一个冬天但在母亲的悉心照料下，他成功地活了下来。他出生在一个只有两个房间的小木屋里。打的人一起住在那里。他有四个兄弟姐妹。一个奴隶女孩也和他们住在一起小时候，马克·吐温给父母惹了不少麻烦。对他所有的朋友和邻居开玩笑。他开玩笑的性质常常导致暴力。他讨厌上学，经常离家出走。他总是朝着附近的密西西比河的方向走。他被那条浩浩荡荡的河流迷住了。他喜欢在河边一坐就是几个小时。只是guzc在神秘的岛屿和路过的野猪和筱子。他有九次差点淹死。在那些日子里，他了解了许多关于这条河的事情。他了解了所有关于它的历史和不寻常的人谁骑它上下。他永远不会忘记那些场景和那些人。后来，他在《汤姆·索亚》和《哈克贝利·费恩历险记》中把它们写进了美国历史的一部分。马克·吐温继承了他母亲的幽默天赋。很明显，他没有从他的父亲那里继承下来。他曾经说过，他从来没有在他父亲的脸上看到过笑容。另一方面，他的母亲有一种罕见的能力，能以完美的天真说幽默的话。同样的能力使马克·吐温成为一个极其幽默的演说家在他父亲于1847年去世后马克·吐温离开学校，成为一名印刷工人的学徒。他的母亲觉得，他可以通过这种方式谋生，获得一定的教育。他在印刷厂当了两年学徒。在那段时间里，他只收到伙食费和衣服作为报酬。到1853年，马克·特辛厌倦了密苏里州。开始时口袋空空。他曾是一名印刷工。后来，由于读了一本书，他决定去亚马逊河的上游。他计划通过收集和出售可可来发财。他唯一的问题是这次旅行的钱。那个问题以一种不寻常的方式解决了。赫克在人行道上发现了一张50美元的钞票，第二天就动身去巴西了。他一直跑到密西西比河，然后就把钱花光了。接下来，马克·吐温决定成为密西西比河上的一名内河船领航员。他从事他的新职业15个月。他记住了从圣路易斯到新奥尔良这段120摄氏度的路程中所有的转弯、浅水点和危险的岩石。他了解到飞行员的自豪和责任。他成为一名优秀的飞行员。然而，他的wifc作为一个飞行员camc突然结束。这条河在南北战争期间禁止通航。然后他加入了邦联军队。在那之后不久，他连队解散了。他没有再参军。他跟随他的兄弟猎户座内华达州在1861年，因此采取了他的下一个职业。他成了这个边疆地区的一名矿工。在此期间，他开始写一些短篇文章。内华达州弗吉尼亚市的《企业》出版商赏识马克·吐温的才能，给他一份编辑的工作，周薪25美元。为了接受这份工作，他走了125英里，走过了崎岖的道路和崎岖的乡村。就在这一次，他采用了笔名“马克·吐温”后来马克·吐温在旧金山工作了一段时间，然后又当了一名矿工。在他的业余时间。他写了一个叫做“卡拉维拉斯县著名的跳蛙，这个故事使他闻名全国。于是HC决定成为一名全职作家和讲师。赫克在1867年去了纽约，并于1869年出版。这是一个西方人所看到的关于他欧洲之行的报道。这是一本全新的旅行书。这让他在全国享有声誉1870年，马克·吐温在埃尔迈拉与奥利维亚·兰登结婚。纽约这是一段极其成功的婚姻。他们终其一生都奉献给了对方。他的妻子奥利维亚对他的写作产生了强烈而持久的影响。她总是小心翼翼地把所有的脏话去掉。HC总是毫无异议地接受她的改变。结婚后的几年里，他写了两本使他最感到遗憾的书:1876年的《汤姆索亚历险记》和1884年的《哈克贝利费恩历险记》。1889年亚瑟王宫廷里的康涅狄格州扬基人不幸的是，马克·吐温根本没有商业能力。他从写作和演讲中获得了巨大的利润，但一次又一次，他在错误的投资中亏了钱。他终于在1895年在出版业上失去了全部财产，他承担了所有债务。为了偿还这些债务，他写了大量的故事。他作了一次成功的环球旅行。他终于可以付钱了。尽管为此付出了巨大的努力，他仍然能够保持健康。他的生活中有比经济上的更糖糕的悲剧。然而。他的妻子奥莉薇亚于1904年去世。他的三个孩子此前已经去世七十岁的时候，他的头发全白了。他决定买+四套白西装和一百条白领带。他从头到脚只穿白色衣服，直到他在雷丁去世。马克·吐温

热心网友马克·吐温（l835～1910）美国作家，本名塞缪尔·朗赫恩·克莱门斯。马克·吐温是其笔名。出生于密西西比河畔小城汉尼拔的一个乡村贫穷律师家庭，从小出外拜师学徒。当过排字工人，密西西比河水手、南军士兵，还经营过木材业、矿业和出版业，但有效的工作是当记者和写作幽默文学。 马克·吐温是美国批判现实主义文学的奠基人，世界著名的短篇小说大师。他经历了美国从“自由”资本主义到帝国主义的发展过程，其思想和创作也表现为从轻快调笑到辛辣讽刺再到悲观厌世的发展阶段。他的早期创作，如短篇小说《竞选州长》（1870）、《哥尔斯密的朋友再度出洋》（1870）等，以幽默、诙谐的笔法嘲笑美国“民主选举”的荒谬和“民主天堂”的本质。中期作品，如长篇小说《镀金时代》（1874，与华纳合写）、代表作长篇小说《哈克贝里·费恩历险记》（1886）及《傻瓜威尔逊》（1893）等，则以深沉、辛辣的笔调讽刺和揭露像瘟疫般盛行于美国的投机、拜金狂热，及暗无天日的社会现实与惨无人道的种族歧视。《哈克贝里·费恩历险记》通过白人小孩哈克跟逃亡黑奴吉姆结伴在密西西比河流浪的故事，不仅批判封建家庭结仇械斗的野蛮，揭露私刑的毫无理性，而且讽刺宗教的虚伪愚昧，谴责蓄奴制的罪恶，并歌颂黑奴的优秀品质，宣传不分种族地位人人都享有自由权利的进步主张。作品文字清新有力，审视角度自然而独特，被视为美国文学史上具划时代意义的现实主义著作。19世纪末，随着美国进入帝国主义发展阶段，马克·吐温一些游记、杂文、政论，如《赤道环行记》（1897）、中篇小说《败坏了哈德莱堡的人》（1900）、《神秘来客》（1916）等的批判揭露意义也逐渐减弱，而绝望神秘情绪则有所伸长。

In 1864 Twain left for California,and worked in San Francisco as a reporter.He visited Hawaii as a correspondent for The Sacramento Union,publishing letters on his trip and giving lectures.He set out on a world tour,traveling in France and Italy.His experiences were recorded in 1869 in The Innocents Abroad,which gained him wide popularity,and poked fun at both American and European prejudices and manners. The success as a writer gave Twain enough financial security to marry Olivia Langdon in 1870.They moved next year to Hartford.Twain continued to lecture in the United States and England.Between 1876 and 1884 he published several masterpieces,Tom Sawyer (1881) and The Prince And The Pauper (1881).Life On The Mississippi appeared in 1883 andHuckleberry Finn in 1884. In the 1890s Twain lost most of his earnings in financial speculations and in the failure of his own publishing firm.To recover from the bankruptcy,he started a world lecture tour,during which one of his daughters died.Twain toured New Zealand,Australia,India,and South Africa.He wrote such books as The Tragedy Of Pudd"head Wilson (1884),Personal Recollections Of Joan Of Arc (1885),A Connecticut Yankee in King Arthur"s Court (1889) and the travel book Following The Equator (1897).During his long writing career,Twain also produced a considerable number of essays. The death of his wife and his second daughter darkened the author"s later years,which is seen in his posthumously published autobiography (1924).Twain died on April 21,1910

Small people always do that, but the really great make you feel that you, too, can become great.” “In a good bookroom you feel in some mysterious way that you are absorbing the wisdom contained in all the books through your skin, without even opening them.” “Substitute "damn" every time you"re inclined to write "very;" your editor will delete it and the writing will be just as it should be.” “Reader, suppose you were an idiot.

It was here first.” “I did not attend his funeral, but I sent a nice letter saying I approved of it.” “God created war so that Americans would learn geography.” “I was gratified to be able to answer promptly, and I did. I said I didn"t know.” “Never allow someone to be your priority while allowing yourself to be their option.” “But who prays for Satan? Who, in eighteen centuries, has had the common humanity to pray for the one sinner that needed it most?” “The difference between the almost right word and the right word is really a large matter. "tis the difference between the lightning bug and the lightning.” “Truth is stranger than fiction, but it is because Fiction is obliged to stick to possibilities; Truth isn"t.” “I do not fear death. I had been dead for billions and billions of years before I was born, and had not suffered the slightest inconvenience from it.” “Wrinkles should merely indicate where the smiles have been.” “Books are for people who wish they were somewhere else.”

马克吐温，美国著名作家，喜欢捉弄别人。一旦一个玩笑他。有一天，马克吐温应邀（被邀请）在一个小镇谈谈。午饭他遇到了一个年轻人，他的一个朋友。这个年轻人说他有个叔叔和他。他告诉马克吐温，他叔叔没有笑过，而且没什么能使hisuncle微笑或大笑。“你把你的叔叔和我说话，”马克吐温说。“我确信我能让他笑”那天晚上，年轻人和他的叔叔坐在前面。马克吐温开始说话。他讲了几个有趣的故事。这使房间里的每个人都笑了。但他没有笑。马克吐温告诉更多的有趣的故事，但这个老男人仍然保持沉默。马克吐温告诉他有趣的故事。最后他停下来。他很累，很失望（失望的）。几天之后，马克吐温告诉一个朋友对他发生了什么事。“噢，”他的朋友说。“我知道那位老人。他已经聋了（聋）多年。”希望对你有用哦！

在自己家里用 　　一次，美国着名作家马克·吐温在邻居家发现一本书深深吸引了他，他问邻居是否可以借阅。邻居说：“欢迎您随时来读，只要您在这里看。您知道，我有个规矩：我的书不能离开这个房子。” 　　几个星期后，邻居来向马克·吐温借锄草机，马克·吐温说：“当然可以，但是按我的规矩，你得在我家里的草坪上使用它。” 　　马克吐温的幽默故事 有一次，美国小说家马克.吐温到芝加哥一家旅店住宿，有人告诉他此地蚊子特别厉害。他在服务台登记房 间时，一只蚊子正好飞来。马克.吐温对服务员说：“我早就听说贵地蚊子十分聪明，果不其然。它竟会预先来看我的房间号码，以便夜晚光临，饱餐一顿。” 服务员听了不禁大笑。这一夜，马克.吐温睡得很好，因为服务员记住了房间号码，认真地事先做了一切该做的事。 一次偶然的机会，马克·吐温与雄辩家琼西·m·得彪应邀参加同一晚宴。 席上演讲开始了，琼西·m·得彪滔滔不绝，情感丰富他讲了20分钟，赢得了一片热烈的掌声。然后轮到马克·吐温演讲。 马克·吐温站起来，面有难色地说：“诸位，实在抱歉，会前琼西·m·得彪先生约我互换演讲稿，所以诸位刚才听到的是我的演讲，衷心感谢诸位认真的倾听及热情的捧场。然而，不知何故，我找不到琼西·m·得彪先生的讲稿，因此我无法替他讲了。请诸位原谅我坐下。” 法国名人波盖取笑美国人历史太短，说：“美国人没事的时候，往往喜欢怀念祖宗，可是一想到祖父一代，就不能不打住了。” 马克·吐温回敬说：“法国人没事的时候，总是想弄清他们的父亲是谁，可是很难弄清楚。” 当马克·吐温还是一个不大知名的作家时，有人把他介绍给格兰特将军。 两人握过手后，马克·吐温想不出一句可讲的话，而格兰特也保持平日的那种缄默态度。最后还是马克·吐温结结巴巴地说了一句：“将军，我感到很尴尬，你呢？” 马克·吐温外出乘车。当列车员检查车票时，他翻遍了每个衣袋，也没有找到自己的车票。刚好这个列 车员认识他，于是就安慰马克·吐温说：“没关系，如果您实在找不到车票，那也不碍事。” “咳！怎么不碍事，我必须找到那张该死的车票，不然的话，我 怎么知道自己要到哪儿去呢？” 马克·吐温常常向人说起他小时候的一段伤心往事。据说，马克·吐温出生时是双胞胎，他和他的双胞胎兄弟两人长得一模一样，连他们的母亲也分辨不出来。 有一天，保姆为他们洗澡时，其中一个不小心跌入浴缸淹死了，没有人知道淹死的究竟是双胞胎中的哪一个。 “最叫人伤心的就在这里。”马克·吐温说，“每个人都以为我是那个活下来的人，其实我不是。活下来的是我弟弟。那个淹死的人是我。” 曾有一位专门喜欢在细节上吹毛求疵的批评家指责马克·吐温说谎。马克·吐温回答说：假如你自己不会说谎，没有说谎的本领，对谎话是怎样说的一点知识都没有，你是怎样判断我是说谎呢？只有在这方面经验丰富的人，才有权这样明目张胆地武断指责。” 一次马克·吐温应邀赴宴。 席间，他对一位贵妇说：“夫人，你太美丽了！”不料那妇人却说：“先生，可是遗憾得很，我不能用同样的话回答你。” 头脑灵敏，言辞犀利的马克·吐温笑着回答：“那没关系，你也可以像我一样说假话。” 马克·吐温收到一封信。这是一位青年人写来的，他想向马克·吐温请教成为大作家的诀窍。信中说：“听说鱼含大量的磷质，而磷是有利于脑子的。看来要成为一个大作家，一定要吃很多鱼吧？但不知道你究竟吃的什么鱼，又吃了多少呢？” 马克·吐温回信说：“看来，你得吃一条鲸才行。”

known前面加个well

马克吐温是美国著名作家。他写了许多故事，其中许多是有趣的故事。这些故事仍被许多世界各地的人阅读。除了写作，他还非常喜欢打猎和捕鱼，所以他有一年去缅因州度假，并在那里的丛林里度过了三个非常愉快的星期。 当他回家，他开着车，带着他的行李到火车站。在那里，他请搬运工人把行李放进火车火车。然后，他进入吸烟车厢和坐在一个舒适的位子上。当他进去的时候这个车厢是空的，但几分钟后，另一名男子进来坐在到了他对面的座位。马克吐温看着那个男子，并认为这名男子看上去很不愉快。然而，如果在这种情况下，不说点什么将不太礼貌，于是，他对那个男子说“早上好”，他们开始交谈。 首先，他们谈到了天气，然后他们谈论缅因州。陌生人说： “我们缅因州有一些漂亮的森林。如果不在那里呆一段时间，那将是来缅因州的一个遗憾。我想你已经到我们的丛林里去过了，是吗？ ” “是的，我去过了” ，马克吐温回答说。 “我刚刚花了三个星期在那里，我也度过了一段美好的时光。让我告诉你一些其他的事儿，虽然缅因州在这个季节不允许捕鱼，但是我还是得到了两百磅的非常好的鱼在我的行李里面，放在这列火车上。我喜欢吃鱼，所以我把它们放进冰里带回家起。我想请问你是谁，先生？ “ 陌生人看着马克吐温几秒钟，然后回答说： “我是警察。我的工作是抓捕那些在错误的时间狩猎和捕鱼的人。你是谁？ ” 当他听到这儿的时候，马克吐温感到惊讶和害怕。他很快地想了一下，然后回答， “嗯，我来告诉你，先生。我是美国最会说大话的人。 ”有帮助的话请给好评哦！

MarkTwain的名言有：1、强者，藐视困难，弱者，仰视困难。2、当你发现自己属于大多数这边的时候，就应该停下来反思一下。3、绝不要和愚蠢的人争论，他们会把你拖到他们那样的水平，然后回击你。4、一切脆弱的东西之中，最脆弱的就是不曾在烈火中试炼过的道德。5、每个人就像一轮月亮，不愿意将黑暗的一面让别人看到。

马克。吐温一辈子都想投资做点什么，但是两次投资之后都已失败而告终，最后还欠了很多债。后来只有在其经纪人的安排下和其太太四处演讲以获取资金还债。马克。吐温的人生可谓是“透支”的人生啊!

可以是马克吐温是美国记者、作家和演讲家。他的风格是幽默，被称之为最伟大的幽默家。他的汤姆索亚历险记和哈克贝利芬历险记被誉为美国历史上最伟大的作品。Mark Twain, American journalist, writer and lecturer, is known for his humor style and is regarded as the greatest humorist. His two adventures are considered as the best books in American history.

马克吐温的很多介绍里都有啊。A Famous Story of Mark Twain里有。原文如下： Mark Twain was a famous American writer. He wrote many stories and many of them were funny stories. These stories are still read by many people all over the world. Besides writing, he also liked hunting and fishing very much, so one year he went to Maine for a holiday and spent three very pleasant weeks in the woods there. When he had to go back home, he drove to the station with his baggage. There he asked a porter to put it into the train. Then he got into the smoking car and sat down in one of the comfortable seats there. The car was empty when he got in, but a few minutes later, another man got in and sat down on the seat opposite his. Mark Twain looked at the man and thought that this man looked quite unpleasant. However, it would be impolite to say nothing in that situation, so he said good morning to the man, and they began to talk. First they talked about the weather and then they talked about Maine. The stranger said, "We have some beautiful woods in Maine. It would be a pity to come to Maine without spending some time there. I suppose you have been in our woods, haven"t you?" "Yes, I have," answered Mark Twain. "I"ve just spent three weeks there and I had a very good time, too. And let me tell you something. Although fishing isn"t allowed in Maine at this season, I"ve got two hundred pounds of beautiful fish with my baggage in this train. I like to eat fish, so I packed it in ice to take it home with me. May I ask who you are, sir?" The stranger looked at Mark Twain for several seconds and then answered, "I"m a police officer. My job is to catch people who hunt and fish during the wrong seasons. And who are you?" Mark Twain was surprised and frightened when he heard this. He thought quickly and then answered, "Well, I"ll tell you, sir. I"m the man who tells the biggest lies in America."

马克·吐温在给自己取笔名时想起了密西西比河上测水员的呼号“MarkTwain”，其意为两英寻，等于2.2米，在此深度，船只可以安全通过。于是，马克·吐温用它作为自己的笔名。

Mark twain was born Samuel Langhorne Clemens in the town of Florida, Missouri, in 1835

Mark Twain (pseudonym of Samuel Langhorne Clemens, 1835-1910), was an American writer, journalist and humorist, who won a worldwide audience for his stories of the youthful adventures of Tom Sawyer and Huckleberry Finn. Clemens was born on November 30, 1835 in Florida, Missouri, of a Virginian family. He was brought up in Hannibal, Missouri. After his father"s death in 1847, he was apprenticed to a printer and wrote for his brother"s newspaper. He later worked as a licensed Mississippi river-boat pilot. The Civil War put an end to the steamboat traffic and Clemens moved to Virginia City, where he edited the Territorial Enterprise. On February 3, 1863, "Mark Twain" was born when Clemens signed a humorous travel account with that pseudonym. In 1864 Twain left for California, and worked in San Francisco as a reporter. He visited Hawaii as a correspondent for The Sacramento Union, publishing letters on his trip and giving lectures. He set out on a world tour, traveling in France and Italy. His experiences were recorded in 1869 in The Innocents Abroad, which gained him wide popularity, and poked fun at both American and European prejudices and manners. The success as a writer gave Twain enough financial security to marry Olivia Langdon in 1870. They moved next year to Hartford. Twain continued to lecture in the United States and England. Between 1876 and 1884 he published several masterpieces, Tom Sawyer (1881) and The Prince And The Pauper (1881). Life On The Mississippi appeared in 1883 andHuckleberry Finn in 1884. In the 1890s Twain lost most of his earnings in financial speculations and in the failure of his own publishing firm. To recover from the bankruptcy, he started a world lecture tour, during which one of his daughters died. Twain toured New Zealand, Australia, India, and South Africa. He wrote such books as The Tragedy Of Pudd"head Wilson (1884), Personal Recollections Of Joan Of Arc (1885), A Connecticut Yankee in King Arthur"s Court (1889) and the travel book Following The Equator (1897). During his long writing career, Twain also produced a considerable number of essays. The death of his wife and his second daughter darkened the author"s later years, which is seen in his posthumously published autobiography (1924). Twain died on April 21, 1910.

找到微软 Entity Framework4.1 的下载页，有个 Entity Framework4.1 Update 1 的链接，去下载。删除原 Entity Framework4.1 ，安装Entity Framework4.1 Update 1版本，然后就可以ADO.NET DbContext Generator 就不会出现“未能找到文件”，我是这种情况，但这样子就不能安装EF4.1LanguagePack (zh-CN)，因为语言包是 for Entity Framework4.1 RTM的。

　1、分页的时候，尽量在数据库里面去分页。　　2、尽量禁用延迟加载，尽量使用预加载和显式加载查询。　　3、注意事务的简短性。　　4。查询出来的实体,如果不考虑删除和修改,请用notracking　　5。批量删除和修改,不要用先把实体查询出来,然后再逐个删除和修改。这样会产生大量的语句,效率肯定会低。　　6。使用已编译的查询,虽然到ef5。0, linq 查询是自动缓存的。但使用编译查询会比自动缓存的效率高。　　7。预生成视图,　　8。还有一点,就是对于复杂的查询,我们要随时监控生成的查询语句。　　转载，仅供参考。

注意这里面每个.net framework都有两个版本，一个带有bundle字眼，一个没有。一个安装的DLL里面包含SQLite.Interop.dll，而另一个没有。如果你运行代码的时候报逗无法加载SQLite.Interop.dll地的错误，则将安装文件中的SQLite.Interop.dll拷贝到Bin文件中即可。或是在NuGet下载的packagesSystem.Data.SQLite.Core.1.0.94.0uild中也有对应的程序。示例代码Model.cspublic class Person { public Int64 Id { get; set; } //注意要用Int64 public string FirstName { get; set; } public string LastName { get; set; } } public class MyContext : DbContext { public DbSet<Person> Persons { get; set; } public MyContext() : base("SqliteTest") { } }Program.csstatic void Main(string[] args) { MyContext context = new MyContext(); var empList = context.Persons.OrderBy(c => c.FirstName).ToList(); Console.WriteLine(empList.Count); Person people = new Person() { FirstName = "Hello", LastName = "World" }; context.Persons.Add(people); context.SaveChanges(); Console.ReadLine(); }示例代码很简单，就是用EF对Person表进行新增与查看。配置config文件如果你是用NuGet获取Sqlite，会自动在config中配置一些相关的信息。<?xml version="1.0" encoding="utf-8"?><configuration> <configSections> <!-- For more information on Entity Framework configuration, visit --> <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" /> </configSections> <connectionStrings> <add name="SqliteTest" connectionString="data source=SqliteTest.db" providerName="System.Data.SQLite.EF6" /> </connectionStrings> <startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" /> </startup> <system.data> <DbProviderFactories> <add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".NET Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" /> <remove invariant="System.Data.SQLite" /> <remove invariant="System.Data.SQLite.EF6" /> <add name="SQLite Data Provider (Entity Framework 6)" invariant="System.Data.SQLite.EF6" description=".NET Framework Data Provider for SQLite (Entity Framework 6)" type="System.Data.SQLite.EF6.SQLiteProviderFactory, System.Data.SQLite.EF6" /> </DbProviderFactories> </system.data> <entityFramework> <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework"> <parameters> <parameter value="v11.0" /> </parameters> </defaultConnectionFactory> <providers> <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" /> <provider invariantName="System.Data.SQLite.EF6" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6" /> </providers> </entityFramework></configuration>其中数据连接串是：<add name="SqliteTest" connectionString="data source=SqliteTest.db" providerName="System.Data.SQLite.EF6" />注意提供程序集是System.Data.SQLite.EF6。但是这个配仍然是错误的。如果此时运行程序，会报错：Unable to determine the provider name for provider factory of type "System.Data.SQLite.SQLiteFactory". Make sure that the ADO.NET provider is installed or registered in the application config.或中文错误信息：未找到具有固定名称逗System.Data.SQLite地的 ADO.NET 提供程序的实体框架提供程序。请确保在应用程序配置文件的逗entityFramework地节中注册了该提供程序。意思是EF没有找到提供System.Data.SQLite.SQLiteFactory的dll，我们看看现在config中的entityFramework节点：<entityFramework> <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework"> <parameters> <parameter value="v11.0" /> </parameters> </defaultConnectionFactory> <providers> <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" /> <provider invariantName="System.Data.SQLite.EF6" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6" /> </providers> </entityFramework>有System.Data.SQLite.EF6与System.Data.SqlClient，确实没有名称为System.Data.SQLite的提供程序。这里我一直不明白为什么sqlite会去找名称为System.Data.SQLite的提供程序，因为我们在连接串中配置的provider也是System.Data.SQLite.EF6。那我们就在EF的配置节点中增加一个名为System.Data.SQLite的provider，但type仍然是System.Data.SQLite.EF6。最终的配置如图：红色部分是配置有变化的地方。这里再运行程序就可以了。注意：1.连接串的配置。 数据连接串可以指定绝对地址，也可以指定相对地址。像我的data source=SqliteTest.db，则SqliteTest.db要在Bin文件夹中，如果是web程序可以通过Data Source=|DataDirectory|SqliteTest.db来配置在App_Data文件平中。2.如果没有指定数据库中的表文件名，EF生成的SQL表都是用复数表示。就像我的程序中实体名是Person,但EF去查找的表名会是People。所以在数据库中定义的表名是People。3.不支持CodeFirst模式，您需要自己先设计好Sqlite的表结构。

Entity Framework主要是把关系型数据库也就是Sqlserver那些转化一下，让程序员在写C#的代码的时候，能用类的方式来操作数据库，而不是用sql字符串。我们可以把它用用C/S的工程当中，也可以把它用到 B/S的工程当中。为了展示EntityFramework的使用方法，我们首先得建立一个例子解决方案。这个解决方案的最基础的普通三层结构，因为数据的访问主要靠EntityFramework来实现，所以数据访问层的实现基本看不出来了，使得整个解决方案好像就是个两层的一样。

今天刚接触Entity Framework，确实在简单使用非常方便 我现在有一个需求 将对象的公共字段 如 id createDate 等 提取出来作为BaseEntity 在xxxModelFirst.Designer.cs 的model对象继承这个BaseEntity　　public partial class BaseEntity : EntityObject { /// <summary> /// 没有元数据文档可用。 /// </summary> [EdmScalarPropertyAttribute(EntityKeyProperty = true, IsNullable = false)] [DataMemberAttribute()] public global::System.Int32 Id { get { return _Id; } set { if (_Id != value) { OnIdChanging(value); ReportPropertyChanging("Id"); _Id = StructuralObject.SetValidValue(value); ReportPropertyChanged("Id"); OnIdChanged(); } } } private global::System.Int32 _Id; partial void OnIdChanging(global::System.Int32 value); partial void OnIdChanged(); /// <summary> /// 没有元数据文档可用。 /// </summary> [EdmScalarPropertyAttribute(EntityKeyProperty = false, IsNullable = false)] [DataMemberAttribute()] public global::System.Boolean Enable { get { return _Enable; }

　　 A、新特性　　　　　　a、支持对关系型数据的批量更新。　什么意思就不用细说了吧，在这之前，很多人喷粪EF，就是说他的更新效率太低，如果要实现批量更新，特别插入时，需要借助sql语句或是第三方工具类。相信这是很多人期待的功能；　　　　　　b、支持唯一约束。它允许你在实体内除主键外额外标识一个键，将他们用作外键。　　 B、行为(Behavior)改变　　 在EF6和前期的版本中，顶层API就有很多不直观的行为，虽然EF7尽可能是保持顶层API的相同，但仍去掉了一些限制并添加了一些我们期待的行为。什么意思呢？这听起来有点迷糊，举个例子来说明吧，以前的查询，虽然Linq给我们带来了很大方便，但限制多呀，整个Linq查询翻译成一条单独的sql查询，Linq查询中只能包含EF能翻译成sql的语句或方法；还有就是sql的生成，有时生成了很复杂、效率不高，且不是我们希望的sql语句。EF7改变这种情况，可以返回多结果集，sql评估工作也不是在数据库端来做了，变更到客户端。这样就为生成sql提供了很大的灵活性。如果还有点晕，没关系，先有个印象就行。　　 C、变得更加简单、灵活　　 直接使用一个例子来说明吧。我们想通过EF的元数据来获取Blog实体被映射到数据库中的哪一张表。在这之前，我们的代码会是这样:在EF7中会代码会是这样：using (var db = new BloggingContext()) { var tableName = db.Model.GetEntityType(typeof(Blog)).Relational().Table; }　　　D、去掉了一些特性　　　　　　a、每类型映射多个实体集（MEST)。这个特性，估计用的人很少，正是因为使用的人少，所以才去掉。它是什么意思呢？就是一个类型对应数据库中的多张表，例如：表Product 和 RetriedProduct都映射到Product类。如果你还有这样的需求，使用继承是更好的选择。　　　　　　b、非常复杂的类型映射。在EF6.x中，可能在一个继承映射中组合了TPH,TPT和TPC。EF7不再支持这种复杂的映射了，它要求你的CLR 类型尽量跟表结构保持一至。至于为什么，我相同不少人到现在都还没有弄明白什么是TPH,TPT,TPC,那更说不上灵活运行了，这也是导致EF6.x MetadataWorkspace异常复杂的主要原因。　　　　　　c、去掉edmx建模。这可能会让很多人失望，因为它曾经给我们带来多么美好的回忆。但它有很多的不足，比较一些复杂的需求，不适应ddd分层设计，不符合现在流行的POCO等。最主要的是，有更好的选择code-based建模，这就是我们常说的code-first。 可能你会有疑问，怎么code-first和edmx是平级概念，它不是跟db-first、model-first平级的吗？ 没错，它是跟edmx平级的，更详细的解释请查看我的另一篇博客Code First is a bad name，这些年我们对Code First的理解都错了 ！很震惊吧？　　　　　　d、去掉ObjectContext API。它陪EF一起成长，到EF4.1时才被DbContext弄到幕后.不过DbContext只是它的外观模式，底层仍然是使用的它。有时需要使用一些高级的功能时，我们还想办法把它找出来。去掉它并不意味着它以前的一些功能不能用了。EF7重写了底层，把之前一定需要它才能使用的api包含在了DbContext中，并且调用更加清晰，简单。　　　　　　e、去掉了延迟加载。 这功能相信大家不陌生，它一直被当成EF的一大特点，但现在，它将要从EF7中去掉。我不确定最终的版本微软会不会把它请回来，因为这一点存在很大的争论。无论是我们这些开发人员，还是EF的开发团队。我个人是支持去掉的。一，不是所有的应用都需要延迟加加载；二、不少的EF使用者对它没有深入的去了解，经常会有人问，为什么会出现"无法完成该操作，因为 DbContext 已释放"这样的问题。这说明这个功能反而给一部份使用者带来了困惑。　　这些变化并不是最终的，也许文中说的，会发生改变。当然这里也不可能列出所有的变化点，毕竟EF7还在处于开发过程中。总之，它是一个革命性的版本，以至于有人在争论应该叫他EF7呢，还是EF1。　　　　　　E、对非关系型数据库的支持，文章开头部分已经有提到，这里就不多说了。四、EF7的开发计划　　相信，很多人和我一样，去年就开始期待EF7的发布。一年多长长的等待，可是它还没有出来，到底要什么时候呢？微软的计划是2016年，所以大家得耐心等待。不过，有个好消息是，它是开源的，最新的源代码在github上，如果你想了解更多的细节，可以到下面的地址（https://github.com/aspnet/EntityFramework）去克隆或是下载源代码。下面是EF的开发计划表

我们在使用Entity Framework的时候经常会把数据库中的某一个视图映射为EF的实体，但是如果数据库视图中的列没有包含表的主键列，EF会报出警告说视图没有主键，导致视图映射为实体失败，错误如下： 表/视图“{0}”未定义主键，无法推断有效的主键。已排除该表/视图。要使用该实体，您将需要检查架构，添加正确的键并对它取消注释。English translation: The table/view "{0}" does not have a primary key defined and no valid primary key could be inferred. This table/view has been excluded. To use the entity you will need to review your schema, add the correct keys and uncomment it. 这时候我们需要在视图里面用sql的isnull函数生成一列值不能为null的列就行了。比如假设现在我们的数据库中本来有一个视图叫V_Customer，它返回的列中没有包含查询表dbo.CustomersBoughtCarsSurvey的主键列

在Entity Framework中，我们可以通过ToTable("表名")指定表名进行映射，Entity Framework会根据指定的表名构建SQL语句，如果在这里加上数据库名和Schema名（也就是ToTable("数据库.dbo.表名")），是不是可以实现跨数据库查询呢？于是，我们根据这个思路进行了试验，结果发现了Entity Framework不能进行跨数据库查询的秘密：Entity Framework会对ToTable()中指定的表名进行处理，加上中括号，如果没有指定Schema名，会在表名前加上[dbo]，比如：ToTable("表名")，SQL语句中的表名是[dbo].[表名]。而在加“中括号”时的不正确有处理，成为了罪魁祸首。我们试图组装一些特殊字符串骗过Entity Framework，都没成功。目前我们在用Reflector在Entity Framework的代码中寻找凶手，只有找到了凶手，知道了作案手段，才能知道是否有可能解决这个问题。下面用代码爆一下料：BlogDbContext的代码：public class BlogDbContext : DbContext{ public DbSet<PostText> PostTexts { get; set; } protected override void OnModelCreating(DbModelBuilder modelBuilder) { modelBuilder.Entity<PostText>().ToTable("blog_PostBody"); }}

Spark已经取代Hadoop成为最活跃的开源大数据项目，但是，在选择大数据框架时，企业不能因此就厚此薄彼近日，著名大数据专家Bernard Marr在一篇文章中分析了Spark和 Hadoop 的异同Hadoop和Spark均是大数据框架，都提供了一些执行常见大数据任务的工具，但确切地说，它们所执行的任务并不相同，彼此也并不排斥虽然在特定的情况下，Spark据称要比Hadoop快100倍，但它本身没有一个分布式存储系统而分布式存储是如今许多大数据项目的基础，它可以将 PB 级的数据集存储在几乎无限数量的普通计算机的硬盘上，并提供了良好的可扩展性，只需要随着数据集的增大增加硬盘因此，Spark需要一个第三方的分布式存储，也正是因为这个原因，许多大数据项目都将Spark安装在Hadoop之上，这样，Spark的高级分析应用程序就可以使用存储在HDFS中的数据了与Hadoop相比，Spark真正的优势在于速度，Spark的大部分操作都是在内存中，而Hadoop的MapReduce系统会在每次操作之后将所有数据写回到物理存储介质上，这是为了确保在出现问题时能够完全恢复，但Spark的弹性分布式数据存储也能实现这一点另外，在高级数据处理（如实时流处理、机器学习）方面，Spark的功能要胜过Hadoop在Bernard看来，这一点连同其速度优势是Spark越来越受欢迎的真正原因实时处理意味着可以在数据捕获的瞬间将其提交给分析型应用程序，并立即获得反馈在各种各样的大数据应用程序中，这种处理的用途越来越多，比如，零售商使用的推荐引擎、制造业中的工业机械性能监控Spark平台的速度和流数据处理能力也非常适合机器学习算法，这类算法可以自我学习和改进，直到找到问题的理想解决方案这种技术是最先进制造系统（如预测零件何时损坏）和无人驾驶汽车的核心Spark有自己的机器学习库MLib，而Hadoop系统则需要借助第三方机器学习库，如Apache Mahout实际上，虽然Spark和Hadoop存在一些功能上的重叠，但它们都不是商业产品，并不存在真正的竞争关系，而通过为这类免费系统提供技术支持赢利的公司往往同时提供两种服务例如，Cloudera 就既提供 Spark服务也提供 Hadoop服务，并会根据客户的需要提供最合适的建议Bernard认为，虽然Spark发展迅速，但它尚处于起步阶段，安全和技术支持基础设施方还不发达，在他看来，Spark在开源社区活跃度的上升，表明企业用户正在寻找已存储数据的创新用法
