create+table语句中的not+Null用于实现数据库的实体完整性吗?

是的,CREATE TABLE语句中的NOT NULL用于确保数据库表中的列不能为空,从而实现实体完整性。当你在创建一个表时,使用NOT NULL关键字来指定某一列不允许为空。这样,如果有人试图插入一条数据,并且在该列中没有提供值,就会出现错误,从而确保了数据的完整性。NOT NULL关键字可以应用于各种数据类型,包括字符串、数字、日期和时间等。

COMP9311 Database Systems Lab8

本次lab的目的是练习Relational Design Theory。 What functional dependencies are implied if we know that a set of attributes X is a candidate key for a relation R? 因为X是candidate key,所以X可以推出所有其他attribute。即X --> R - X What functional dependencies can we infer do not hold by inspection of the following relation? 当A = a, a时,B = 1, 1, C = x, y,所以A推出B保留,而A是不能推出C的,B也不能推出C,AB不能推出C; 当A = b, b时,B = 2, 2, C = y, z,和上面结论一致,没有新的结论; 当A = c, d时,B = 1, 2, C = z, x,确认A-->B。 同理,判断B-->A?因为B= 1, 1, 1时,A = a, c, a,所以B不能推出A。 判断C-->A?因为C = x, x时,A = a, d,所以C不能推出A 判断C-->B?因为C = x, x时,B = 1, 2,所以C不能推出B Suppose that we have a relation schema R(A,B,C) representing a relationship between two entity sets E and F with keys A and B respectively, and suppose that R has (at least) the functional dependencies A → B and B → A. Explain what this tells us about the relationship between E and F. A-->B说明每个A有一个B对应,反之,也就是说A和B是一一对应的,用离散数学的术语说是双射bijection。 Consider the relation R(A,B,C,D,E,F,G) and the set of functional dependencies F = { A → B, BC → F, BD → EG, AD → C, D → F, BEG → FA } compute the following: 根据上述F,可以推出的结论在括号中显示:A-->B(AB),A/B/AB无法推出任何结论,所以A+ = {A, B} 根据上述F,可以推出的结论在括号中显示:A-->B(ABCEG), BC-->F(ABCEFG), BEG-->FA(ABCEFG),所以ACEG+ = {A, B, C, E, F, G} 根据上述F,可以推出的结论在括号中显示:BD-->EG(BDEG), D-->F(BDEFG), BEG-->FA(ABDEFG), AD-->C(ABCDEFG),所以ACEG+ = {A, B, C, D, E, F, G} Consider the relation R(A,B,C,D,E) and the set set of functional dependencies F = { A → B, BC → E, ED → A } 根据F,如果选定A作为candidate key,则B可以被A推导,C不可以被推导,所以candidate key更新为AC,D不可以被推导,所以candidate key更新为ACD,E可以被BC推导; 如果选定B作为candidate key,C不可以被推导,所以candidate key更新为BC,D不可以被推导,所以candidate key更新为BCD,E可以被BC推导,A可以被ED推导; CD在上述两中情况下都是candidate key,继续思考E: 如果选定E作为candidate key,C不可以被推导,所以candidate key更新为EC,D不可以被推导,所以candidate key更新为ECD,A可以被ED推导,B可以被A推导。 综上,所有candidate keys是ACD, BCD, CDE 3NF的要求是:对所有的FDs X --> Y (1)要么Y是X的子集 (2)要么X是超键(candidate key/ super key) (3)要么Y是key中的一个attribute 因为-->右侧的BEA都是candidate key的attribute,所以符合3NF 通常3NF都符合BCNF,但个别的不符合。BCNF的要求是:对所有的FDs X --> Y (1)要么Y是X的子集 (2)要么X是超键(candidate key/ super key) 二者的区别是BCNF不能接受Y是key的一个attribute。 左边没有super key,而任何一个FD都不是子集关系,所以不是BCNF。 Consider a relation R(A,B,C,D). For each of the following sets of functional dependencies, assuming that those are the only dependencies that hold for R, do the following: a. List all of the candidate keys for R. b. Show whether R is in Boyce-Codd normal form (BCNF)? c. Show whether R is in third normal form (3NF)? DAC可以被推出,C推出的最多,所以先假设B是candidate key,B-->C(BC), C-->D(BCD), C-->A(ABCD)。candidate key是B。 C不是key却出现在-->左边,所以不是BCNF。 C-->D,C, D都是非key,所以不是3NF。 CA可以被推出,优先思考BD,假设B是candidate key,B-->C(BC),D不可以被推出,所以更新candidate key为BD,D-->A(ABCD)。candidate key是BD。 因为左边都不是superkey,而左右又不是子集关系,所以不是BCNF;而右边又不是single key attribute,所以也不是3NF。 DA可以被推出,优先思考BC,假设BC是candidate key,不能推出任何内容,更新candidate key为ABC,ABC-->D(ABCD);更新candidte key为BCD,D-->A(ABCD)。所以candidate key是ABC或BCD。 D-->A中的A是key的一部分,所以被允许,符合3NF。 D-->A的D不是key,二者也不是子集关系,所以不属于BCNF。 BDC可以被推出,假设candidate key是A,A-->B(AB), A-->C(ABC), BC-->D(ABCD)。所以candidate key是A。 BC-->D左右都是non-key,不符合3NF。 BC不是key,不符合BCNF。 ABCD都可以被推出,假设candidate key是A,A无法推出任何,更新candidate key为AB,AB-->C(ABC), AD-->D(ABCD);假设candidate key是B,B无法推出任何,更新candidate key为BC,C-->A(ABC), AB-->D(ABCD);假设candidate key是C,C-->A(AC),更新candidate key为CD,D-->B(ABCD);假设candidate key是D,D-->B(BD),更新candidate key为AD,AB-->C(ABCD)。所以candidate key可能是AB, BC, CD, AD。 因为-->右侧的CDAB都是candidate key中的attribute,所以符合3NF。 如果candidate key是AB,那么C-->A既不是子集关系,C也不是key,所以不符合BCNF。 可以直接看出candidate key是A。 既符合3NF,也符合BCNF。 Specify the non-trivial functional dependencies for each of the relations in the following Teams-Players-Fans schema and then show whether the overall schema is in BCNF. Functional dependencies: Team: name → captain Player: name → teamPlayedFor Fan: name → address TeamColours: no non-trivial fds FavouriteColours: no non-trivial fds FavouritePlayers: no non-trivial fds FavouriteTeams: no non-trivial fds non-trivial FDs就是找非子集的dependency,如果只有两个variable,都是key,那么都是trivial的。以上都属于superkey推出non-key,所以都是BCNF。 Specify the non-trivial functional dependencies for each of the relations in the following Trucks-Shipments-Stores schema and then show whether the overall schema is in BCNF. Functional dependencies: Warehouse ... warehouse# → address Source ... no non-trivial fds Trip ... trip# → date,truck Truck ... truck# → maxvol,maxwt Shipment ... shipment# → volume,weight,trip,store Store ... store# → storename,address 和上面练习思路一致,这里也都是BCNF。 For each of the sets of dependencies in question 4: (1) if R is not already in 3NF, decompose it into a set of 3NF relations; (2) if R is not already in BCNF, decompose it into a set of BCNF relations candidate key是B,不是BCNF,不是3NF (1)decompose to BCNF C-->D违背了BCNF,拆解出来CD。 剩余ABC,FD变为C-->A, B-->C。C-->A违背了BCNF,拆解出来CA。 剩余BC,FD变为B-->C,符合BCNF。 所以最终BCNF为(R1(CD), R2(CA), R3(BC)) (2)decompose to 3NF minimal cover: C-->D, C-->A, B-->C key: B F" = C-->DA, B-->C CDA(KEY = C), BC(KEY = B) candidate key是BD,不是BCNF,不是3NF (1)decompose to BCNF B-->C违背BCNF,拆解出来BC。 剩余ABD,FD变为D-->A,违背BCNF,拆解出来DA。 剩余BD,FD为空。 所以最终BCNF为(R1(BC), R2(DA), R3(BD)) (2)decompose to 3NF minimal cover无法合并,所以3NF是BC(KEY = B), DA(KEY = A), BD(KEY = BD) candidate key是ABC/BCD,不是BCNF,是3NF (1)decompose to BCNF D-->A违背BCNF,拆解出来DA。 剩余BCD,FD为空。 所以最终BCNF为(R1(DA), R2(BCD)) candidate key是A,不是BCNF,不是3NF (1)decompose to BCNF BC-->D违背BCNF,拆解出BCD。 剩余ABC,FD变为A-->B, A-->C,都符合BCNF。 所以最终BCNF为(R1(BCD), R2(AB), R3(AC)) (2)decompose to 3NF minimal cover和FDs一致,所以3NF是AB(KEY = A), BCD(KEY = BC), AC(KEY = A) candidate key是AB, BC, CD, AD,不是BCNF,是3NF (1)decompose to BCNF C-->A违背BCNF,拆解出来CA 剩余BCD,FD变为D-->B,不符合BCNF,拆解出来DB。 剩余CD,FD为空。 所以BCNF为(R1(CA), R2(DB), R3(CD)),但彼此之间没有联系,所以还要加入联系,变成(R1(CA), R2(DB), R3(CD), R4(ABC), R5(ABD)) candidate key是A,是BCNF,是3NF Consider (yet another) banking application that contains information about accounts, branches and customers. Each account is held at a specific branch, but a customer may hold more than one account and an account may have more than one associated customer. Consider an unnormalised relation containing all of the attributes that are relevant to this application: acct# - unique account indentifier branch# - unique branch identifier tfn - unique customer identifier (tax file number) kind - type of account (savings, cheque, ...) balance - amount of money in account city - city where branch is located name - customer"s name i.e. consider the relation R(acct#, branch#, tfn, kind, balance, city, name) Based on the above description: 根据定义acct# --> kind, balance;branch#-->city;tfn-->name Account(acct#(key), kind, balance, branch) Branch(branch#(key), city) Customer(tfn(key), name) CustAcc(customer(key), account(key)) They fit in 3NF. Consider a schema representing projects within a company, containing the following information: pNum - project"s unique identifying number pName - name of project eNum - employee"s unique identifying number eName - name of employee jobClass - type of job that employee has on this project payRate - hourly rate, dependent on the kind of job being done hours - total hours worked in this job by this employee This schema started out life as a large spreadsheet and now the company wants to put it into a database system. As a spreadsheet, its schema is: R(pNum, pName, eNum, eName, jobClass, payRate, hours) Based on the above description: primary key是unique,所以根据定义推出 pNum → pName eNum → eName jobClass → payRate pNum,eNum → jobClass,payRate,hours pNum → pName is a dependency on part of the key to fix: decompose to R1(pNum,eNum,eName,jobClass,payRate,hours) and R2(pNum,pName) eNum → eName is a dependency on part of the key to fix: decompose to R1(pNum,eNum,jobClass,payRate,hours) and R2(pNum,pName) and R3(eNum,eName) jobClass → payRate is a dependency on a non-key attribute to fix: decompose to R1(pNum,eNum,jobClass,hours) and R2(pNum,pName) and R3(eNum,eName) and R4(jobClass,payRate) pNum → pName eNum → eName jobClass → payRate pNum,eNum → jobClass,hours Project(pNum, pName) Employee(eNum, eName) AwardRates(jobClass, payRate) Assignment(pNum, eNum, jobClass, hours) The new schema is not in 3NF because we have lost the dependency: pNum,eNum → payRate 后续还有若干练习,和前面的题目大同小异,不再赘述。

如何使用Mock来测试Files,Database和ContentProviders

  首个先我们创建一个应用,功能很简单就是读取该应用目录下的一个txt文件内容,并展示到应用的activity上。  public class MockContextExampleActivity extends Activity {  public final static String FILE_NAME = “myfile.txt”;  private TextView mTv;  @Override  public void onCreate(Bundle savedInstanceState) {  super.onCreate(savedInstanceState);  setContentView(R.layout.main);  mTv = (TextView) findViewById(R.id.TextView01);  final byte[] buffer = new byte[1024];  try {  final FileInputStream fis = openFileInput(FILE_NAME);  final int n = fis.read(buffer);  mTv.setText(new String(buffer, 0, n-1));  } catch (Exception e) {  mTv.setText(e.toString());  mTv.setTextColor(Color.RED);  }  }  //这里写了个getText方法,测试工程会用到。  public String getText() {  return mTv.getText().toString();  }  运行一下,此时我们的包目录下没有myfile.txt,页面显示的可能是个错误。OK,然后我们创建两个文件。一个名为myfile.txt,一个test.myfile.txt。前者用于应用中显示的文件内容,后者是作为测试Mock调用的。  echo “This is real data” >data/data/com.example.aatg.mockcontextexample/files/myfile.txt  echo “This is *MOCK* data” >data/data/com.example.aatg.mockcontextexample/files/test.myfile.txt  再次运行下,应该可以看到Activity上显示的是This is real data。  OK,下面开始编写测试代码。我们的目的是测试这个app能够正确读取文件,假设现在我怕是不是开发在代码里写死了“This is real data”这句话(作为测试,有点怀疑精神很正常)。OK,现在我用另外一个文件test.myfile.txt来代替myfile.txt会不会出错。  public class MockContextExampleTest extends ActivityUnitTestCase<MockContextExampleActivity> {  private static final String PREFIX = “test.”;  private RenamingDelegatingContext mMockContext;  public MockContextExampleTest() {  super(MockContextExampleActivity.class);  }  @Override  protected void setUp() throws Exception {  super.setUp();  mMockContext = new RenamingDelegatingContext(getInstrumentation().getTargetContext(), PREFIX);  mMockContext.makeExistingFilesAndDbsAccessible();  }  @Override  protected void tearDown() throws Exception {  super.tearDown();  }  public void testSampleTextDisplayed(){  setActivityContext(mMockContext);  startActivity(new Intent(), null, null);  final MockContextExampleActivity mActivity = getActivity();  assertNotNull(mActivity);  String text = mActivity.getText();  assertEquals(“This is *MOCK* data”, text);  }  }  主要看下RenamingDelegatingContext函数的使用,PREFIX是表示文件或数据库的前缀。另外这里为什么使用getTargetContext方法而不是getContext,后者我们经常在UiTest中使用到。这里其实看下注释就明白了:  //getContext():The instrumentation"s package context.  //getTargetContext(): A Context in the target application.  运行下测试,pass。这说明getText方法返回的string已经是This is *MOCK* data 而不是 This is real data了。这我就可以证明,开发没有写死这段话。以上就是RenamingDelegatingContext函数如何来mock文件的,数据库的使用也是一样的。

respected和respectable有什么区别?

又到了为小伙伴们解惑的时候了 (*u2766ωu2766),respected 指被许多人尊敬,并不具有太强烈的社会地位的意味。而respectable 更强调整个社区中的公认认可和尊敬。这里就给大家总结了一个它们基础知识的表格,可以先简单了解一下先:了解完respected和respectable的基础知识后,现在就来看看它们的具体区别~(@^_^@)~1、定义和词性的区别Respected 是一个形容词,意为“受人尊敬的”,指某人在社交生活中因为其过往的成功或高贵的品德在他人中拥有良好的声誉。而 Respectable 也是一个形容词,意为“可尊敬的,有声望的”,其主要含义是指一个人在社区中受到普遍尊敬的程度。例句:- He is a respected leader in the community.(他是社区里备受尊敬的领袖。)- She is a respectable businesswoman with a successful career.(她是一位事业有成的值得尊敬的女商人。)2、程度和范围的区别Respected 指被许多人尊敬,并不具有太强烈的社会地位的意味。而 Respectable 更强调整个社区中的公认认可和尊敬。例句:- The respected professor was invited to give a speech at the conference.(受人尊敬的教授被邀请在会议上发言。)- He is a respectable member of the police force.(他是警察队伍中受人尊敬的成员。)3、过去和现在的区别Respected 更多指过去的成就和声誉,而 Respectable 更多指现在或者近期的表现和声誉。例句:- The respected soldier fought bravely in World War II.(这位备受尊敬的士兵在第二次世界大战中表现勇敢。)- She is a respectable teacher who has a great impact on her students.(她是一位备受尊敬的教师,对她的学生有巨大的影响。)4、社会地位和品德的区别Respected 通常意味着社会地位,而 Respectable 更侧重于人的品德和事件的正面影响。例句:- The respected businessman owned a large company.(这位受人尊敬的商人拥有一家大公司。)- He has a respectable character that is admired by many people.(他有可尊敬的品德,为很多人所敬慕。)5、认同和评价的区别Respected 通常是表示客观事实,是对某一定方式生活的肯定。而 Respectable 是评价性的词汇,是人们对某人的社会角色和行为的认同和评价。例句:- The respected actor received many awards and honors during his career.(这位受人尊敬的演员在他的职业生涯中获得了许多奖项和荣誉。)- He is a respectable member of the community due to his charitable contributions.(由于他的慈善贡献,他是社区中受人尊敬的成员。)

tableview:cellforrowatindexpath:为什么只调用一次

我所要实现的效果是在vc1上添加vc2的view,vc2的view上有子视图tableview,tableview的delegate和datasource设置为vc2。也就是说tableview:cellForRowAtIndexPath:是在vc2中实现的。刚开始我以为是因为没有在主线程中调用reloadData方法造成的,因为tableview:cellForRowAtIndexPath:是在tableview显示的时候(UI 刷新)调用,而 UI 刷新是在主线程中执行的。BUT,把reloadData放入主线程后,无卵用。。 经过排查,发现我的方法调用顺序是这样的:viewDidLoad -> setupView -> reloadData,也就是说,我在viewWillAppear之前(视图还未显示)调用了reloadData方法。viewDidLoad是视图加载完成后调用,此时视图还未开始显示。而tableview:cellForRowAtIndexPath:是在具体的cell显示时执行,绘制cell。我把reloadData放在viewDidLoad中才造成了这个问题。 那么现在有两种解决方法: 第一种:把reloadData放在vc2的viewWillAppear中。 第二种:将vc2写成NSObject的子类,它有一个属性view,将这个view添加到vc1.view上,然后在vc1的viewWillAppear中去实现vc2的tableview的reloadData。 建议使用第一种方法,封装性较好,层次清晰。不过需要注意的是,vc1可能不仅仅添加vc2的view,可能还需要添加vc3、vc4、vc5等等。如果把子vc的view全部加在vc1上,会耗费大量的内存。可以使用addChildViewController,把需要添加的vc都加上,但addSubview只添加需要显示的vc的view,切换vc时调用transitionFromViewController:toViewController:duration:options:animations:completion方法。

tableside service造句 tableside serviceの例文 "tableside service"是什麼意思

Josh and Michelle were assigned tableside service , preparing an octopus appetizer. Tableside service is a ritual that dates back to French court pfe, said Karen Hess, a cupnary historian. He was preparing for what had long been one of the dying acts in restaurant pfe : tableside service . Dining rooms are less formal and more crowded, and waiters are not as well trained, all of which has diminished the art of tableside service . At Centopre on Madison Avenue, Nora Jimenez, the general manager, said tableside service helps distinguish her restaurant from the hundreds of other Itapan restaurants in Manhattan. That was in the 1970s, when nouvelle cuisine was ing into vogue, and classic tableside service from rolpng carts was replaced by dishes artfully placed on oversize dinnerware in the kitchen. "" Service "": T and Bret were assigned tableside service , with Marino emphasizing the importance of talking to and entertaining the customers, something that Bret found himself having to do a lot, due to his team"s struggles, when he entertained guest Bree Turner. Tableside service , and its brief, shining acts of spcing, deboning, saucing and meticulously pampering food before the diner"s eyes, has been popping up in many unexpected places in New York, from a restaurant focused on kaiseki to one that is progressive and French to a tiny Itapan trattoria on a quiet street in Brooklyn. It"s difficult to find tableside service in a sentence. 用 tableside service 造句挺难的

如何使用bootstrap-table进行后端排序

Bootstrap的后台数据绑定、特殊列处理及列的排序功能1.数据绑定一般做程序设计,很少是使用json文件直接绑定数据。基本上我们都是使用编程语言进行数据获取,并做数据绑定。放置一个Table控件<table id="table" ></table>调用javascript的代码<script >$("#table").bootstrapTable({url: "tablejson.jsp", //数据绑定,后台的数据从jsp代码search:true,uniqueId:"Id",pageSize:"5",pageNumber:"1",sidePagination:"client",pagination:true,height:"400",columns: [{field: "Id",title: "中文"}, {field: "Name",title: "Name"}, {field: "Desc",title: "Desc"}],});2.特殊列处理在实际应用中,我们需要增加我们的特殊列,例如是操作列,看下列的js代码 增加了一个特殊列{field: "#",title: "control",formatter:function(value,row,index){var del="<a href="Deletewww.bjldfw.comaction?Id="+row.Id+"" rel="external nofollow" rel="external nofollow" >删除</a>";var updt="<a href="supdate.jsp?Id="+row.Id+"" rel="external nofollow" rel="external nofollow" >修改</a>";var add="<a href="Include.jsp?Id="+row.Id+"" rel="external nofollow" rel="external nofollow" >增加</a>"return del+" "+updt+"&nbsp"+add;}}js的代码修改为<script >$("#table").bootstrapTable({url: "tablejson.jsp", //数据绑定,后台的数据从jsp代码search:true,uniqueId:"Id",pageSize:"5",pageNumber:"1",sidePagination:"client",pagination:true,height:"400",columns: [{field: "Id",title: "中文"}, {field: "Name",title: "Name"}, {field: "Desc",title: "Desc"},{field: "#",title: "control",formatter:function(value,row,index){var del="<a href="Deletewww.bjldfw.comaction?Id="+row.Id+"" rel="external nofollow" rel="external nofollow" >删除</a>";var updt="<a href="supdate.jsp?Id="+row.Id+"" rel="external nofollow" rel="external nofollow" >修改</a>";var add="<a href="Include.jsp?Id="+row.Id+"" rel="external nofollow" rel="external nofollow" >增加</a>"return del+" "+updt+"&nbsp"+add;}}], }); 3.列的排序,排序主要是在列中增加了一个属性{field: "Name",title: "Name",<br><em id="mceDel">sortable:true</em>}以上就是JavaScript BootStrap Table后台数据绑定、特殊列处理、排序功能详解的详细内容

英语作文:An unforgettable day

One of the most unforgettable days of my life occurred last year when I went on a hiking trip with my friends to a nearby mountain. The breathtaking beauty of nature and the invigorating exercise made this day truly memorable.We started our hike early in the morning, with the sun barely visible over the horizon. The cool breeze and chirping of the birds made the atmosphere feel ever so fresh. It was a steep hike, but our determination kept us going. We passed through lush forests and clear streams. The scenery was so spectacular that we stopped frequently to take in the stunning view.As we approached the summit, the view became more and more breathtaking. The views of the surrounding mountains were extraordinary. We could see small villages nestled among the valleys and forests. The clouds were like a blanket, covering the mountains tops.Once we reached the peak, we felt on top of the world. The sense of accomplishment was indescribable. We sat down to rest and enjoy the scenery before starting the descent. We shared snacks and laughter while enjoying the serene environment.The descent was not easy, but we helped each other navigate the tougher sections. We stopped by a stream to rest and take a dip. The cool water was refreshing, and the scenery was amazing. A few hours later, we arrived back at the base camp, tired but exhilarated.Overall, that day left an indelible imprint on me. It was more than just a hike or a day out; it was a day filled with adventure, friendship, and nature"s beauty. I will cherish those memories forever.

英语作文my unforgettable experience

An Unforgettable Experience Everybody has some experience he canu2019t forget. For me, the most unforgettable experience was taking part in an English conversation test. This took place about two years ago when I had to take an oral English test in order to go abroad for further study. At that time, I had difficulty even in reading and writing, not to mention speaking. Naturally I felt very nervous when it was my turn to face the examiners. They asked me something about sports, sightseeing, Chinese culture, my purpose of going to America and so on. I was simply too tense to give any sensible answer. In fact, I could hardly open my mouth. The interview took about ten minutes, but it seemed years to me. When it was over, my shirt was thoroughly wet. This was the first time I talked to foreigners in English. This was an experience I am not likely to forget.

An unforgettable experience 初中英语作文 80词左右

Last summer, I went on a camping trip with my family to a beautiful mountain. One day, we decided to hike to the top of the mountain. The trail was steep and difficult, but we were determined to reach the summit. It took us several hours to climb to the top, but the view was breathtaking. We could see for miles in every direction. We had a picnic lunch and enjoyed the scenery. On the way back down, we took a different path and discovered a hidden waterfall. It was an unforgettable experience and I will always cherish the memories of that day.

unforgettable 为什么双写t

动词是闭音节的单音节词,或是以重读闭音节结尾的多音节词,末尾只有一个辅音字母时,这个辅音字母须双写; forget前面是e的音,以t结尾 最后三个音是辅+元+辅
