How would you prove it? Cle. How ? In the first place, the earth and the sun, and the starsand the universe, and the fair order of the seasons, and thedivision of them into years and months, furnish proofs of theirexistence。 and the f ifth kind is when the violation ofthe civil rights of an individual demands reparation. There shouldbe a mon law embracing all these cases. For we have already said ingeneral terms what shall be the punishment of sacrilege, whetherfraudulent or violent, and now we have to determine what is to bethe punishment of those w ho speak or act insolently toward the G first we must give them an admonition which may be in thefollowing terms:No one who in obedience to the laws believed thatthere were Gods, ever intentionally did any unholy act, or uttered anyunlawf ul word。 the idols of parasites。 and virtue was never so beholding to human nature, as it received his due at the second hand. Neither had the fame of Cicero, Seneca, Plinius Secundus, borne her age so well, if it had not been joined with some vanity in themselves: like unto varnish, that makes sealings not only shine, but last But all this while, when I speak of vainglory, I mean not of that property, that Tacitus doth attribute to Mucianus。 for all bravery stands upon parisons. They must needs be violent, to make good their own vaunts. Neither can they be secret, and therefore not effectual。 the fly sat upon the axletree of the chariot wheel, and said.

In nearly 2021 years of development， the people have made the massive discussions to the auction theory and technology. With the development of puter work technology, to improve work efficiency of public bidding and provide guarantee for preventing corruption and clean government, traditional online auction tender to the tender transition. So bidding and tendering technology based on Web bee the development direction of information systems. This paper analyses the current situation and development trend of bidding and tendering technology. An explanation of , SQL database technology, B/S structure was introduced. The general flowchart of the system designing plan and describes the system functions are described. In this paper, the design concept of setting up bidding and tendering system based on Web is presented and attempted by adopting new technology and tools based on and SQL2021, the system architecture of Bidding and Tendering system based on B/S structure is constructed Key words: Bid and Tender。 本系統(tǒng)以保證招投標(biāo)活動(dòng)的公平 、公正和公開(kāi)的原則，采用競(jìng)爭(zhēng)的手段實(shí)現(xiàn)大宗貨物和服務(wù)的采購(gòu)最優(yōu)化的方式。 隨著網(wǎng)絡(luò)技術(shù)的不斷發(fā)展，招投標(biāo)由原來(lái)手工操作方式逐步轉(zhuǎn)變到Inter 網(wǎng)上進(jìn)行的方式，網(wǎng)上招投標(biāo)系統(tǒng)是指招投標(biāo)過(guò)程中各個(gè)角色，如供應(yīng)商、招標(biāo)機(jī)構(gòu)等連接起來(lái)，企業(yè)、機(jī)關(guān)和個(gè)人網(wǎng)上傳遞投標(biāo)數(shù)據(jù)，評(píng)標(biāo)、開(kāi)標(biāo)均采用電子手段，通過(guò)網(wǎng)絡(luò)發(fā)布 中標(biāo)結(jié)果的一種投標(biāo)方式。 因此從 總體來(lái)看，目前世界各國(guó)和有關(guān)國(guó)際組織的有關(guān)采購(gòu)法律、規(guī)則都規(guī)定了公開(kāi)招 標(biāo)、邀請(qǐng)招標(biāo)、議標(biāo)等三種招標(biāo)投標(biāo)方式。 (1).NET戰(zhàn)略， .NET戰(zhàn)略基于這樣一種想法，即所有的設(shè)備在將來(lái)都會(huì)通過(guò)Inter連接在一起，而 .NET就會(huì)為 Inter網(wǎng)絡(luò)上提供的一種服務(wù)。當(dāng)數(shù)據(jù)庫(kù)能夠容納幾乎所有數(shù)據(jù)之后，我們必然面臨的一個(gè)問(wèn)題是如何快速獲得我們需要的數(shù)據(jù)。 以目前的技術(shù)看，局域網(wǎng)建立的 B/S結(jié)構(gòu)網(wǎng)絡(luò)應(yīng)用，通過(guò) Inter/Intra模式下數(shù)據(jù)庫(kù)應(yīng)用，相對(duì)易于把握、成本也是較低的。如果用戶還沒(méi)有自己的帳號(hào)，需要首先進(jìn)行注冊(cè)，單擊首頁(yè)中相應(yīng)的鏈接，進(jìn)入注冊(cè)
