連接SQL Server數(shù)據(jù)庫(kù)[外文翻譯]

To connect SQL Server database
First we introduce the basic knowledge of the database, be regarded as the warm-up exercise that study database weave distance front!
1.warm-up exercise
Needing first avowal is relation database that database knowledge that we here introduce all point. The so-called relation database is to mean data as that the form gather, passing to establish simple form an a kind of database for of relation to
defining construction.
I ignore the watch at how saving way in physics in the document in database is, it can see to make an a line for with row, with electronics form is similar with the row. In relation database, the line were called the record, but the row then is called word segment.
This form inside each an all in formations for is a record, it including particular customer, but each record then included the same type with the word segment of the quantity: Customer's number, name etc.
Form is logic set that a kind of related information that press a line of arranging with row, similar in single form in work.
Each row of the word a database form inside calls a word segment. Watch is from every kind of word a definition of its containment of, each word a data for describing its implying. While creating to set up a database, the beard assign for each word segment a the piece belongs to the sex with the other according to the type, biggest length. The word segment can include every kind of word sign, arithmetic figure even sketch.



連接SQL Server數(shù)據(jù)庫(kù)
我們先介紹一下數(shù)據(jù)庫(kù)的基本知識(shí)，算是學(xué)習(xí)數(shù)據(jù)庫(kù)編程前的熱身運(yùn)動(dòng)吧！
1. 熱身運(yùn)動(dòng)
　　首先需要聲明是，我們這里介紹的數(shù)據(jù)庫(kù)知識(shí)都是指的關(guān)系數(shù)據(jù)庫(kù)。所謂關(guān)系數(shù)據(jù)庫(kù)就是將數(shù)據(jù)表示為表的集合，通過(guò)建立簡(jiǎn)單表之間的關(guān)系來(lái)定義結(jié)構(gòu)的一種數(shù)據(jù)庫(kù)。
　　不管表在數(shù)據(jù)庫(kù)文件中的物理存儲(chǔ)方式如何，它都可以看作一組行和列，與電子表格的行和列類似。在關(guān)系數(shù)據(jù)庫(kù)中，行被稱為記錄，而列則被稱為字段。此表中每一行是一個(gè)記錄，它包含了特定客戶的所有信息，而每個(gè)記錄則包含了相同類型和數(shù)量的字段：客戶號(hào)、姓名等等。
表 是一種按行與列排列的相關(guān)信息的邏輯組，類似于工作單表。
