1、启动ACCESS建空數據庫，给數據庫取名“數據庫名”。
2、建一个表，如果有excel數據可直接导入或在设计视图里面建表，如段名分别为：学号、姓名、性别、出生日期、家庭住址等。给表取名“表名”。
3、用數據表做數據源，建立需要的查询。
一个简单的數據庫就建成了。
我认为數據庫在网站开发中扮演者重要的角色，它掌管着大量的重要數據。它是网站开发的核心，也可以说它是一个默默无闻的工作者

數據庫是用来存储數據的，其中分好多类，小型的有ACCESS，中型的有SQL SERVER，大型的有ORACLE，可根据自已的需要选用。
其重要性是显而易见的，没有數據庫，只可以做静态的页面，无法实时更新或存储历史數據。數據庫的设计在大型项目中尤为重要，好的數據庫设计可以網站開發者更方便，讓網站訪問時間縮短好多倍，會讓網站訪問起來更快。

數據庫的优势：
支持事務
單個屬性的修改比較方便
支持並發讀寫
數據庫的缺点：
處理Blob、Text類型的性能不強
占用大量內存
文件的優勢：
運維成本低
方便做版本控制

"I acquaint the inhabitants of Liège of this, that they may understand what fate threatens them if they should assume a similar attitude. A raiding party of hostiles had passed near the fort, and had killed, with particular atrocity, a family of settlers. The man and his wife had been tortured to death, the baby had had its brains beaten out against the trunk of a tree, a very young child had been hung by the wrist tendons to two meat hooks on the walls of the ranch-house, and left there to die. One big boy had had his eyelids and lips and nose cut off, and had been staked down to the ground with his remains of a face lying over a red-ant hole. Only two had [Pg 196]managed to escape,—a child of ten, who had carried his tiny sister in his arms, twenty miles of ca?ons and hills, to the post. Every engine of the English Court was put in motion to prevent the Electoral Prince from coming. Oxford had an interview with Schutz, in which he repeated that it was his applying for the writ to the Lord Chancellor instead of to the queen that had done all the mischief; that her Majesty, had it not been for this untoward incident, would have invited the Prince to come over and spend the summer in England—forgetting, as Schutz observed, that the minute before he had assured him that the queen was too much afraid of seeing any of that family here. He advised Schutz—who could not be convinced that he had done anything irregular in his application, quoting numerous proofs to show that it was the accustomed mode of applying for writs—to avoid appearing again at Court; but Schutz, not seeming disposed to follow that advice, immediately received a positive order to the same effect from the queen through another channel. Schutz, therefore, lost no time in returning to Hanover to justify himself. At the same time, Lord Strafford was instructed to write from the Hague, blaming the conduct of Schutz in applying for the writ in the manner he did, as disrespectful to the queen; for, though strictly legal for an absent peer to make such application, the etiquette was that he should defer it till he could do it personally. Strafford ridiculed the idea of any movement being afoot in favour of the Pretender, and observed that, as to sending him out of the Duke of Lorraine's territory, it was not practicable, because the French king maintained that he had fulfilled the treaty, Lorraine not being any part of France. On the other hand, there were striking signs that the cause[17] of Hanover was in the ascendant. Men who watched the course of events decided accordingly. Marlborough, who so lately had been making court to the Pretender, now wrote from Antwerp, urging the House of Hanover to send over the prince without delay to England; that the state of the queen's health made prompt action necessary; and that the presence of the prince in London would secure the succession without risk, without expense, and without war, and was the likeliest measure of inducing France to abandon its design of assisting the Pretender. Shorty had been frantically trying to catch the Deacon's eye, and was making all manner of winks and warning gestures without avail, for the Deacon answered frankly: "Sure you do," Dodd said, and his voice began to rise. He went to the bed, walked along its length to the window, as he talked, never facing Albin. "You know how to make me feel just fine, no worries at all, no complications, just a nice, simple life. With nothing at all in it, Albin. Nothing at all." J. O., I mean it. "Good-bye, my Bluebell, farewell to you, "Cudn't spare one hand to fetch over fifteen—that's a valiant idea. Now d?an't go loitering; fetch out your cattle afore they're roast beef, git out the horses and all the stock—and souse them ricks wot ?un't burning yit." "Do you know my voice?" asked one of Wells's companions. HoME 亚洲春色欧美激情 ENTER NUMBET 0010www.1to1rm.org.cn
