【正文】 and finally, seeking inspiration from biological systems to develop properties such as autoimmune or evolving hardware. The search for inspiration began in 2020, as an initiative of the . Computing Research Committee, prompted in part by an early project of the . Computing Research Association. An academic conference followed, in March 2020, culminating in the publication of the report, Grand Challenges in Computing Research. The seven challenges are presented in seven chapters of the report, each one 遼寧科技大學(xué)畢業(yè)設(shè)計(jì)（論文） 第 32 頁(yè) describing the ultimate goal, the kinds of research needed to reach that goal over a 15year period, and the disciplines that would need to be involved. The suggestions quite detailed for the early years but vaguer and more conjectural as they look further ahead are intended to provoke discussion of the longterm aspirations for puting research. The Grand Challenges report can be found on the BCS Web site As longtime readers already know, I’m a big fan of Bruce Schneier, CTO and founder of BT Counterpane. Besides being a cryptographic and puter security authority, cryptographic algorithm creator, and author of many bestselling books on security, Bruce produces some of the most relevant conversations on puter security. I consider his books, his Cryptogram newsletter, and his blog mustreads for anyone in puter security. Bruce is a guy who pushes us to rethink our currently held paradigms. He lays bare unsubstantiated dogma. I don’t always agree with Bruce. But many of the potent ideas that I disagreed with when he espoused them a half decade ago, I find myself agreeing with years later, ideas like how twofactor authentication won’t stop malicious hackers from stealing gobs of money from the online banking industry, and how the biggest problem with security, in general, is us and our irrational ranking of threats. I distinctly remember Bruce telling me a decade ago how puter security, with all of its advances, was more than likely going to get worse in the future. This was in the face of increasingly accurate antivirus programs, improved patch management, and solid improvements in OS security across all platforms. He。 taking advantage of the behavior of materials at the molecular or subatomic scale to perform calculations in different ways (nanotechnology, quantum puting)。 Scalable ubiquitous puting systems: Not only do we want our devices to interact predictably and reliably, we also want them to interact with every other conceivable device but the plexity of many systems grows much faster than the number of nodes in the system. Computing engineers need scalable design principles: developing and applying them is the goal of this challenge。 In vivo in silico: Through the human genome project, IT has already brought life sciences forward by leaps and bounds, but the next step is to make possible the puter 遼寧科技大學(xué)畢業(yè)設(shè)計(jì)（論文） 第 31 頁(yè) simulation of entire living anisms, allowing scientists to examine a plant, animal or colony of cells in virtual reality, from the cellular scale on upwards, and at different speeds from freezeframe to faster than life。t go wrong, and simulating living creatures in every detail. A grand challenge is a goal recognized one or two decades in advance, achievement of which represents a major milestone in the advance of knowledge or technology, according to a report describing seven grand challenges to inspire and direct IT research, released Tuesday by the British Computer Society (BCS). Some of the challenges identified by the academics are of mercial interest to the puter industry, most notably the development of dependable systems, and of systems that model or behave like living anisms. To achieve the goal of building dependable puter systems, the scientists suggest building a verifying piler, a tool that proves automatically that a program is correct before allowing it to run something first written about in the 1950s. Other themes include the following: Architecture of brain and mind: Once seen as a matter for philosophical debate, explaining the connection between the brain (as puting machinery) and the mind (as a virtual software machine) is increasingly being a scientific problem of interest in the development of information processing systems。 同時(shí)在這里也要感謝在大學(xué)四年里所有教過我的老師，是他們帶領(lǐng)我走進(jìn)計(jì)算機(jī)的殿堂。在我撰寫論文的過程中， 王杰 老師傾注了大量的心血和汗水，無(wú)論是在論文的選題、構(gòu)思和資料的收集方面，還是在論文的研究方法以及成文定稿方面，我都得到了 王杰老師悉心細(xì)致的教誨和無(wú)私的幫助 ，從他身上學(xué)到了很多東西 ，特別是 他 廣博的學(xué)識(shí)、深厚的學(xué)術(shù)素養(yǎng)、嚴(yán)謹(jǐn)?shù)闹螌W(xué)精神和一絲不茍的工作作風(fēng)使我終生受益，在此表示真誠(chéng)地感謝和深深的謝意 。 本文以 CRM 系統(tǒng)（客戶關(guān)系管理系統(tǒng)）開發(fā)過程為例，對(duì) ASP 技術(shù)的特點(diǎn)及應(yīng)用技巧進(jìn)行了較深入的分析和探討，概括起來(lái)，主要有以下幾個(gè)方面： C技術(shù)為開發(fā)人員提供了一個(gè)具有良好接口性和開放性的環(huán)境，本文對(duì) C技術(shù)的特性進(jìn)行了細(xì)致的分析，分析的結(jié)果對(duì)原型系統(tǒng)的開發(fā)起這重要的指導(dǎo)作用，也為讀者更全面的了解 C提供技術(shù)參考； 對(duì) C環(huán)境下與數(shù)據(jù)庫(kù)的連接過程作了詳細(xì)的描述，并對(duì)如何優(yōu)化數(shù)據(jù)庫(kù)連接管理提出了自己的建議； 由于 C的功能十分的強(qiáng)大，通過對(duì)客戶關(guān)系管理系統(tǒng)的開發(fā)，認(rèn)為對(duì)如下幾個(gè)方面進(jìn)一步研究和探討是十分有意義的。 隨著網(wǎng)絡(luò)技術(shù)的不斷更新發(fā)展， C正在逐漸被人們所接受并廣泛應(yīng)用，同時(shí)也給網(wǎng)站開發(fā)者提供了動(dòng)態(tài)頁(yè)面制作的便捷的手段。 顯示警告 城市名稱不能為空，請(qǐng)檢查 ！ ” 顯示警告 城 市名稱不能為空，請(qǐng)檢查 ！ ” 正常 測(cè)試人員 李虹 開發(fā)人員 李虹 項(xiàng)目負(fù)責(zé)人 李虹 遼寧科技大學(xué)畢業(yè)設(shè)計(jì)（論文） 第 27 頁(yè) 結(jié)論 在畢業(yè)設(shè)計(jì)的近三個(gè)多月的時(shí)間內(nèi)，我根據(jù)設(shè)計(jì)要求，查閱了大量資料，了解了庫(kù)存管理的基本流程、進(jìn)行了系統(tǒng)分析、設(shè)計(jì)、編程、調(diào)試運(yùn)行等。 客戶名稱 軟件版本 其他為空 顯示警告信息 所在城市為空 ” 請(qǐng)檢查 ！ ” 顯示警告信 息 “您所在城市不能為空，請(qǐng)檢查 ！ ” 正常 遼寧科技大學(xué)畢業(yè)設(shè)計(jì)（論文） 第 26 頁(yè) 3 輸入 客戶名稱 軟件版本 和 所在城市 ，按 “添加客戶 ”按鈕 客戶名稱 軟件版本 所在城市 添加成功 添加成功 正常 測(cè)試人員 李虹 開發(fā) 人員 李虹 項(xiàng)目負(fù)責(zé)人 李虹 密碼修改模塊測(cè)試用例 表 密碼修改測(cè)試用例 項(xiàng)目軟件 客戶管理 系統(tǒng) 程序版本 . 功能模塊 添加城市 編制人 李虹 功能特性 添加城市 測(cè)試目的 驗(yàn)證是否輸入合法的信息，允許合法 添加 ，阻止非法 不能添加 測(cè)試數(shù)據(jù) 操作步驟 操作描述 數(shù)據(jù) 期望結(jié)果 實(shí)際結(jié)果 測(cè)試狀態(tài) 1 輸入 城市名稱 ，按 “ 確定 ” 按鈕。 遼寧科技大學(xué)畢業(yè)設(shè)計(jì)（論文） 第 25 頁(yè) 測(cè)試用例 設(shè)計(jì)要求 一個(gè) 好 的測(cè)試用例，應(yīng)該包含以下信息： 軟件或項(xiàng)目的名稱 軟件或項(xiàng)目的版本（內(nèi)部版本號(hào)） 功能模塊名 測(cè)試用例的簡(jiǎn)單描述，即該用例執(zhí)行的目的或方法 測(cè)試用例的參考信息（便于跟蹤和參考） 本測(cè)試用例與其他測(cè)試用例間的依賴關(guān)系 本用 例的前置條件，即執(zhí)行本用例必須要滿足的條件，如對(duì)數(shù)據(jù)庫(kù)的訪問權(quán)限 用例的編號(hào)（ ID），如可以是 軟件名稱簡(jiǎn)寫 功能
