My steps are measured, slow, and precise. 1 emit a scarcely audible humming as 1 walk, and my eyes are fixed, as 1 swing my head, not on you, Ignacio, but on the waves at the edge of sight, where they curve up into the sky. 1 stop ten meters short of you, and 1 stand. You go 1 follow, ten meters behind. What do 1 want? Nothing. Yes, 1 will pick up the sticks, and 1 will followfive meters behind. Break them, and put them on the fire. Not all of them, just a few. Yes. Ignacio keeps the fire here burning all the time. Sometimes he ta kes the coals of fire from it to start others, but here, under the big palm log, he has a fire always. The rain does not strike it here. Always the fire. Do you know how he made it the first time? Reply to him! No. No, Patrdo! `No, Patrao.39。 Nicholas had not liked them, and he did not think Ignacio would have liked them either.

He thought of the chipped and rusted old machine that had cleaned the corridorsMaya had called it Corradora, but no one else ever called it any F thing but Hey! It could not (or at least did not) speak, 1 and Nicholas doubted that it had emotions, except possibly a sort of love of cleanness that did not extend to its own person. You will understand, someone was saying inside his head, that motives of all sorts can be divided into two sorts. A doctor? A therapy robot? It did not matter. Extrinsic and intrinsic. An extrinsic motive has always some further end in view, and that end we call an intrinsic motive. Thus when we have reduced motivation to intrinsic motivation we have reduced it to its simplest parts. Take that machine over there. What machine? Freud would have said that it was fixated at the latter anal stage, perhaps due to the care its builders exercised in seeing that the dirt it collects is not released again. Because of its fixation it is, as you see, obsessed with cleanliness and order。ve found out I39。 and then a turtle and a hedgehog that turned into armadillos for the love of God, Montressor.

This kind of management method is considered to be lack of efficiency. It wastes vast of human resources and materials. So the traditional systems must be replaced by the information managing systems based on puter. This system realizes ordering and fetching books for students, teachers and the department of textbooks, retailing books to students, and exchanging books, and damage statistic and counting in ordering books. It provides all sorts of book information for teachers and students. This system is developed by the Visual Studio 2021, with backstage support of SQL Server 2021 Express. This system is applicable for maintaining ma nagement of the work of textbook department for all types of schools. And it can improve the work efficiency greatly. In this paper the process of development and the function of the system will be introduced in details. Key words: Textbooks Management。 本系統(tǒng)主要完成了一個網(wǎng)上教材管理系統(tǒng),其主要實現(xiàn)學(xué)生、教師、教材科的訂書 ,學(xué)生、教師的領(lǐng)書功能,教材零售,因書的質(zhì)量問題換書,報損處理。 。 這個系統(tǒng)是面向教材科庫房的信息管理系統(tǒng)。它是一次性到位的開發(fā),能實現(xiàn)不同的人員,從 不同的地點,以不同的接入方式(比如 LAN, WAN, Inter/Intra 等)訪問和操作共同的數(shù)據(jù)庫;它能有效地保護數(shù)據(jù)平臺和管理訪問權(quán)限,服務(wù)器數(shù)據(jù)庫也很安全 。 也是語言中立的,因此你可以選擇你最熟悉的語言,或者通過幾種語言來共同完成一個應(yīng)用。易于管理。 被設(shè)計成可伸縮的,能為集群和多處理器 環(huán)境設(shè)計提高性能。另外,這些
