Mining adventure cracked IOS

1. Xuanyuan, legend and mobile travel are the most popular martial arts contests. The destiny person has passed many tests, put on a red wedding dress with her beloved, and entered into the palace of happy marriage. In the witness of all the destiny persons and Yuelao, they will marry and accompany her all their lives. At the same time, both sides can get a marriage certificate to record their wedding day, until the silver wedding, the golden wedding, or even the diamond wedding, so that the marriage certificate can witness that the love between lovers is stronger than the gold.

1. The first normal form: there is a partial dependence of non principal attributes on codes R (a, B, c) AB is a code, C is a non principal attribute, B -- & gt; C B decides that part C depends on B. If the range of all attributes in relation R is simple, then relation pattern R is the first normal form

then the first mock exam is: the main key, the primary key can not be empty, the primary key can not be repeated, and the field can not be further divided. For example:

studyno | name | sex | contact

20040901 John mall Email:[email protected] , phone:222456

20040901 mary famale email:[email protected] phone : 123455

the above tables do not conform to the first normal form: plicate primary keys (which are not allowed in the actual database), Moreover, the contact field can be subdivided into

so the correct change is:

studyno | name | sex | email | phone

20040901 John [email protected] 222456

20040902 mary [email protected] 123455

2. The second normal form: there is transitivity dependence of non principal attributes on codes. R (a, B, c) a is code a -- & gt; B ,B--> C If the relational schema R is of the first normal form, and every non primary attribute in the relationship does not depend on the primary key, it is said that R is of the second normal form. Therefore, the main task of the second paradigm is to eliminate some functional dependencies on the premise of satisfying the first paradigm

StudyNo | Name | Sex | Email | Phone | ClassNo | ClassAddress

01 john [email protected] 222456 200401 a building 2

01 Mary [email protected] 123455 200402 a building 3

this table is fully satisfied with the first normal form, and the primary key is composed of studyno and classno, so that it can locate the specified row. However, the classaddress part depends on the keyword (classno - >) classaddress, So it should be changed into two tables:

Table 1

studyno | name | sex | email | phone | classno

01 John [email protected] 222456 200401

01 mary [email protected] 123455 200402

Table 2

classno | classaddress

200401 a building 2

200402 a building 3

3. The third normal form

does not have transitive dependence of non principal attributes on codes and partial dependence Sexual dependence,

studyno | name | sex | email | bounslevel | bouns

20040901 John [email protected] Excellent $1000

20040902 Mary [email protected] Good $600

completely satisfies the second normal form, but there are transitive dependencies between bounslevel and bouns, Change to:

studyno | name | sex | email | bouunsno

20040901 John [email protected] 1

20040902 mary [email protected] 2

bounsno | bounslevel | bouns

1 excellent $1000

2 good $600

here, you can use bounsno as the primary key, for two reasons

(1) do not use characters as the primary key. Some people may say: what if I use numerical value to replace my grade at the beginning

(2) however, if the level name is changed, it is not called 1, 2, 3 or excellent or good, so it is convenient to change. Therefore, it is generally preferred to use fields unrelated to business as keywords

Generally, data rendancy can be avoided by satisfying the first three paradigms

extended data:

when designing a relational database, we should follow different specifications to design a reasonable relational database. These different specifications are called different paradigms. The higher the specification, the smaller the rendancy of the database

at present, there are six paradigms of relational database: the first paradigm (1NF), the second paradigm (2NF), the third paradigm (3NF), the bath cod paradigm (BCNF), the fourth paradigm (4NF) and the fifth paradigm (5NF)

when designing a relational database, we should comply with different specifications to design a reasonable relational database. These different specifications are called different paradigms. Various paradigms present sub specifications, and the higher the paradigm, the smaller the rendancy of the database

at present, there are six paradigms of relational database: the first paradigm (1NF), the second paradigm (2NF), the third paradigm (3NF), the bath cod paradigm (BCNF), the fourth paradigm (4NF) and the fifth paradigm (5NF). The paradigm meeting the minimum requirement is the first paradigm (1NF). The second normal form (2NF) satisfies more specification requirements on the basis of the first one, and so on. Generally speaking, the database only needs to satisfy the third normal form (3NF)

8. Death doesn't fall. Generally speaking, it can only be opened in multiplayer games. The command is like this: if a single person wants to die without falling, he or she has to download a die without falling mod.
