It was far from Amber, somewhere where the shadows go mad. Farther than I like to go. Star k, w ith shifting colors. Fiery. Day without a sun in the sky. Rocks that glided like sailboats across the land. Bra nd there in some sort of towera small point of stability in that f lowing scene. I remembered it, all right. A nd I remembered the presence coiled about the base of tha t tower. Br illiant. Prismatic. Some sort of watchthing, it seemedtoo bright for me to make out its outline, to guess its proper size. Then it all just went away. Instant off. And there I was, staring at the Jac k of Diamonds again, with the guy across from me not knowing w hether to be mad at my long distraction or concerned that I might be having some sort of sick spell. I closed up shop with that hand and went home. I lay stretched out on my bed, smoking and thinking. Brand had still been in A mber when I had departed. Later, though, w hen I had asked after him, no one had any idea as to his whereabouts. He had been having one of his melancholy spells, had snapped out of it one day and ridden off. And that was that. No messages eithereither way. He wasn39。t talking. I tried to figure every angle. He was smart, damn sm art. Possibly the best mind in the family. He was in trouble and he had called me. Eric and Gerard were more the heroic types and would probably have weled the adventure. Caine w ould have gone out of curiosity, I think. Julian, to look better than the r est of us and to score points w ith Dad. Or, easiest of all, Brand could have called Dad himself. Dad would have done something about it. But he had called me. Why? It occurred to me then that maybe one or more of the others had been responsible for his circumstances. If, say, Dad was beginning to favor him . . . Well. You know. Eliminate the positive. And if he did call Dad, he would look like a weakling. So I suppressed my impulse to yell for reinforcements. He had called me, and it was quite possible that I would be cutting his throat by letting anyone back in Amber in on the fact that he had gotten the message out. Okay. What was in it for me? If it involved the succession and he had truly bee fairhaired, I figured that I could do a lot w orse than give him this to remember me by. And if it did not . . . There were all sorts of othe r possibilities. Perhaps he had stumbled onto something going on back home, something it would be useful to know about. I was even curious as to the means he had employed for bypassing the Trumps. So it was curiosity, I39。 主要參考文獻(xiàn) ，陸慰民 ，楊志強(qiáng) .

Dad was still around, and when I noticed that he was getting into one of his grumpy moods, I decided it was time to take a walk. A long one. I had often noticed that his fondness for me tended to increase as an inver se function of my proximity. He gave me a fancy riding crop for a goingaway presentto hasten the process of affection, I suppose. Still, it was a very nice cropsilverchased, beautifully tooledand I made good use of it. I had decided to go looking for an assemblage of all my simple pleasures in one small nook of Shadow. It was a long rideI will not bore you with the detailsand it was pretty far from Amber, as such things go. This time, I was not looking for a place where I would be especially important. That can get either boring or difficult fairly quickly, depending on how responsible you want to be. I wanted to be an irresponsible nonentity and just enjoy myself. Texorami was a wide open port city, with sultry days and long nights, lots of good music, gambling around the cloc k, duels every morning and inbetween mayhem for those who couldn39。 表 字段名 字段類型 字段長度 字段說明 Score_no 數(shù)字 20 編號(hào) Scor_per 數(shù)字 8 考試期號(hào) Score_cla 文本 10 學(xué)生班號(hào) Score_stu 日期 /時(shí)間 20 學(xué)生編號(hào) Score_cou 文本 15 考試課程 Score_sco 數(shù)字 11 考試分?jǐn)?shù) —— 用戶管理數(shù)據(jù)庫 用戶管理數(shù)據(jù)庫利存儲(chǔ)了用戶的信息：用戶名，密碼。還能查詢各個(gè)學(xué)生的情況，姓名、家庭電話、家庭住址、學(xué)號(hào)等各個(gè)消息 (3)課程信息管理 每個(gè)學(xué)期都會(huì)增加一些新的科目，通過本模塊可以輕松的添加以 及更新課程。 \ amp。 數(shù)據(jù)庫在一個(gè)信息管理系統(tǒng)中占有非常重要的位置，數(shù)據(jù)庫結(jié)構(gòu)設(shè)計(jì)的好壞將直接對(duì)應(yīng)用系統(tǒng)的效果產(chǎn)生影響。這些技術(shù)沒有脫離經(jīng)典數(shù)據(jù)庫技術(shù)的要求。其屬性及對(duì)象如下： 1． Align 屬性定義工具條在窗體中的位置 2． ToolTipText 屬性是字符串類型，定義控件的提示字符 3． Style 屬性定義按鈕外觀。 DATA 控件還提供了用來瀏覽不同記錄的各種跳轉(zhuǎn)按鈕。 編程環(huán)境的選擇 微軟公司的 Visual Basic 是 Windows 應(yīng)用程序開發(fā)工具，使目前最為廣泛的、易學(xué)易用的面向?qū)ο蟮拈_發(fā)工具。例如，命令按鈕是一個(gè)對(duì)象，當(dāng)用戶單擊該按鈕時(shí)，將產(chǎn)生一個(gè)“單擊“ (CLICK)事件，而在產(chǎn)生該事件時(shí)將執(zhí)行一段程序，用來實(shí)現(xiàn)指定的操作。 總的來說， Visual Basic 具有以下特點(diǎn)： 可視化編程： 用傳統(tǒng)程序設(shè)計(jì)語言設(shè)計(jì)程序時(shí)，都是通過編寫程序代碼來設(shè)計(jì)用戶界面，在設(shè)計(jì)過程中看不到界面的實(shí)際顯示效果，必須編譯后運(yùn)行程序才能觀察。在局部概念模式設(shè)計(jì)過程中，我們可能會(huì)發(fā)現(xiàn)有些事物既可以抽象為實(shí)體集也可以抽象為屬性或?qū)嶓w集間的聯(lián)系。 對(duì)中層管理人員的訪問，可采用開座談會(huì)、個(gè)別交談或發(fā)調(diào)查表、查看業(yè)務(wù)記錄的方式，目的是了解企業(yè)的具體業(yè)務(wù)控制方式和 約束條件、不同業(yè)務(wù)之間的接口、日?？刂乒芾淼男畔⑿枨笠约邦A(yù)測(cè)未來發(fā)展的潛在信息要求。 需求信息的收集 需求信息的收集又稱為系統(tǒng)調(diào)
