【正文】 據(jù)的集合，這些數(shù)據(jù)是結(jié)構(gòu)化的，無有害的或不必要的冗余，并為多種應(yīng)用服務(wù)；數(shù)據(jù)的存儲(chǔ)獨(dú)立于使用它的程序；對(duì)數(shù)據(jù)庫插入新數(shù)據(jù)，修改和檢索原有數(shù)據(jù)均能按一種公用的和可控制的方式進(jìn)行。 通過 SQL瀏覽器可以對(duì)本地或遠(yuǎn)程的數(shù)據(jù)庫進(jìn)行各種 SQL查詢操作。 數(shù)據(jù)庫引擎是 Delphi 數(shù)據(jù)庫開發(fā)環(huán)境的核心，它由兩種類型的動(dòng)態(tài)鏈接庫組成：一種用于提供核心服務(wù)，另一種用于連接本地或網(wǎng)絡(luò)數(shù)據(jù)庫。 為了便于開發(fā)數(shù)據(jù)庫應(yīng)用程序，在 Delphi集成開發(fā)環(huán)境中，提供了大量的數(shù)據(jù)庫工具軟件用于幫助應(yīng)用程序開發(fā)人員設(shè)計(jì)、編程、測(cè)試和發(fā)行數(shù)據(jù)庫應(yīng)用程序。 (8)從 Delphi8 開始 Delphi也支持 .Net框架下程序開發(fā)。 Delphi 既可用于開發(fā)系統(tǒng)軟件，也適合于應(yīng)用軟件的開發(fā)。開發(fā)人員不必再對(duì)諸如標(biāo)簽、按鈕及對(duì)話框等 Windows 的常見部件進(jìn)行編程。這樣，大大減少了對(duì)服務(wù)器的請(qǐng)求和網(wǎng)絡(luò)上的數(shù)據(jù)傳輸量，提高了應(yīng)用處理的速度。主要特點(diǎn)如下： (1)直接編譯生成可執(zhí)行代碼，編譯速度快。當(dāng)前， DELPHI 也可以為 LINUX平臺(tái)上開發(fā)應(yīng)用，其在 LINUX上的對(duì)應(yīng)產(chǎn)品 Kylix。s performance is much higher than other similar products. (2) support for access to the rules of the respective clients or servers with two programmes, but also allows developers to build a simple set of parts or ponents, from the packaging all the rules, and independent of the servers and clients, all Data transfer through these parts to plete. This has been greatly reduced at the request of the server on the work and data transmission, improving the speed of processing the application. (3) offers a number of quick and easy method development, allowing developers to use the lowest possible number of repetitive work to plete a variety of applications. Use of project templates and experts generator can quickly establish the framework of the project, according to the actual needs of users was gradually improved. (4) a reusable, and scalability. Developers no longer such as labels, buttons and dialog ponents such as the mon Windows programming. Delphi may contain many reusable ponents, allows users to control the development of Windows effect. (5) has powerful data access function. Its data processing tools BDE (BorlandDatabaseEngine) is a standard middleware layer can be used to deal with the current popular data formats, such as xBase, Paradox, but also by the BDE SQLLink directly with Sybase, SQLServer, Informix, Oracle, and other large Database Connection. Delphi can be used to develop system software and application software suitable for the development. (6) The ability to develop a strong work to the rapid development of B / S applications, and its builtin IntraWeb ExpressWeb makes the development of the work efficiency more than any other development tools. (7) use of the unique Delphi VCL class library, making the procedure is the preparation of a coherent clear, VCL now is the best class library, it makes Delphi in the software development industry in an absolute leading position. Users can accordance with their own needs, arbitrary construct, expand, or even the deletion of VCL to meet different needs. (8) From the beginning Delphi8 Delphi also supported. Net framework of the development process. At present DELPHI has bee a brand, not just a development platform or the name of the development of language. DELPHI product from the current CodeGear panies to continue to develop BORLAND the pany is a wholly owned subsidiary of the pany. At present, CodeGear provide for the general development of the DELPHI FOR PHP, in a highly visual manner fully supports objectoriented PHP Web development has greatly enhanced the development site PHP code reuse of a new WEB application development tool. In order to facilitate the development of database applications, in Delphi Integrated Development Environment, with a lot of database tools to help application developers design, programming, testing and distribution of database applications. All of these tools pose a Delphi database application development environment. Its various software tools and their interrelationship. Delphi entire database application development environment from a database engine (BDE), the database engine management procedures (BDE Administrator), the desktop database (DataBase Desktop), SQL browser (SQL Explorere), SQL driver (SQL Links) and ODBC Driver and so on. Delphi database engine is the core of database development environment, from the two types of dynamic link library ponents: to provide a core service and the other for connecting to local or work database. All of these files are installed in the System operating system and user specified by the driver \ Programe Files \ Common Files \ Borland \ Bde \ directory. Database engine is the main function of the database application and the physical separation of the database, the database engine adopted by the alias database (Database Aliases) to identify a local or remote database applications only need this database can be transparent alias of database for a visit. Database engine management procedures (B DE Administrator) mainly for the local Paradox, dBASE data tables and remote SQL database to create tables, indexes to create, query, access and editing operation. SQL browser can be passed on the local or remote SQL database query operation all. SQL driver (SQL Links) is a pany Inprise Delphi client / server versions of the remote database access drivers, ODBC Microsoft in the Windows 95/98 or NT operating system to provide database access drivers. 由 Borland 公司推出的 Delphi 是全新的可視化編程環(huán)境，為我們提供了一種方便、快捷的 Windows應(yīng)用程序開發(fā)工具。正文編排頁碼，裝訂時(shí)連同其封面、目錄一起裝訂。 完成畢業(yè)設(shè)計(jì)論文：高質(zhì)量的完成論文，順利通過畢業(yè)答辯 五、研究進(jìn)度安排 預(yù)計(jì)用 8 階段 完成 本次畢業(yè)設(shè)計(jì) ，具體時(shí)間安排如下： 第 1 階段 ： 搜集相關(guān)資料 ； 第 2 階段 ： 系 統(tǒng)功能分析、系統(tǒng)功能模塊設(shè)計(jì) 、 數(shù)據(jù) 結(jié)構(gòu)設(shè)計(jì) ； 第 3 階段 ：根據(jù) 畢業(yè)設(shè)計(jì) 題目進(jìn)一步查找材料 ， 完成開 題 報(bào)告； 第 4 階段 ： 各功能模塊程序設(shè)計(jì) ； 第 5 階段 ： 各功能模塊程序設(shè)計(jì) 第 6 階段 ： 各功能模塊程序設(shè)計(jì) ； 第 7 階段 ： 進(jìn)行各個(gè)功能模塊測(cè)試，對(duì)系統(tǒng)整體功能模塊進(jìn)行測(cè)試，并加以修改調(diào)試 ，使其更加完善 ； 第 8 階段 ：完成 畢業(yè)設(shè)計(jì)論文 ； 若有剩余時(shí)間，繼續(xù)完善所做系統(tǒng)和所寫論文。系統(tǒng)運(yùn)行的高效性是我追求的目標(biāo)之一。 安全性：幼兒園管理系統(tǒng)必須要有 較 強(qiáng)大的安全性。工作效率的提高就意為著整體水平的提高，是非常值得投資的。 使用 BDE 訪問技術(shù)可方便、快速地對(duì)各種數(shù) 據(jù)庫進(jìn)行訪問。 ： BDE BDE(Boland 數(shù)據(jù)庫引擎 )是一個(gè) API 定義，它為 Delphi 應(yīng)用程序提供 一個(gè)本地?cái)?shù)據(jù)庫支持，是用來驅(qū)動(dòng)數(shù)據(jù)庫的。 Paradox 數(shù)據(jù)表的擴(kuò)展名是 db，此外還有一些其他的文件類型，作為數(shù)據(jù)表的輔助，但用 ADO 對(duì)其進(jìn)行處理時(shí)，使用 *.DB 的文件就已
