【正文】 k 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。對于廣 大的程序開發(fā)人員來講，使用 Delphi 開發(fā)應(yīng)用軟件，無疑會大大地提高編程效率，而且隨著應(yīng)用的深入，您將會發(fā)現(xiàn)編程不再是枯燥無味的工作 —— Delphi的每一個(gè)設(shè)計(jì)細(xì)節(jié)，都將帶給您一份欣喜。當(dāng)前， DELPHI 也可以為 LINUX平臺上開發(fā)應(yīng)用，其在 LINUX上的對應(yīng)產(chǎn)品 Kylix。 Delphi它提供了 500多個(gè)可供使用的構(gòu)件，利用這些部件，開發(fā)人員可以快速地構(gòu)造出應(yīng)用系統(tǒng)。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。在處理速度和存取服務(wù)器方面， Delphi的性能遠(yuǎn)遠(yuǎn)高于其他同類產(chǎn)品。這樣，大大減少了對服務(wù)器的請求和網(wǎng)絡(luò)上的數(shù)據(jù)傳輸量，提高了應(yīng)用處理的速度。利用項(xiàng)目模板和專家生成器可以很快建立項(xiàng)目的構(gòu)架，然后根據(jù)用戶的實(shí)際需要逐步完善。開發(fā)人員不必再對諸如標(biāo)簽、按鈕及對話框等 Windows 的常見部件進(jìn)行編程。 (5)具有強(qiáng)大的數(shù)據(jù)存取功能。 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)。 (7)Delphi使用獨(dú)特的 VCL類庫，使得編寫出的程序顯得條理清晰， VCL是現(xiàn)在最優(yōu)秀的類庫，它使得 Delphi在軟件開發(fā)行業(yè)處于一個(gè)絕對領(lǐng)先的地位。 (8)從 Delphi8 開始 Delphi也支持 .Net框架下程序開發(fā)。 當(dāng)前 DELPHI 產(chǎn)品已經(jīng)由 CodeGear公司繼續(xù)發(fā)展，該公司是 BORLAND 公司的全資子公司。 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、測試和發(fā)行數(shù)據(jù)庫應(yīng)用程序。其各個(gè)工具軟件及其相互間的關(guān)系。 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。數(shù)據(jù)庫引擎的主要 功能是將數(shù)據(jù)庫應(yīng)用程序和物理的數(shù)據(jù)庫分隔開來，在數(shù)據(jù)庫引擎中通過數(shù)據(jù)庫別名 (Database Aliases)來標(biāo)識本地或遠(yuǎn)程的數(shù)據(jù)庫，數(shù)據(jù)庫應(yīng)用程序僅需要此數(shù)據(jù)庫別名就可以透明地對數(shù)據(jù)庫進(jìn)行訪問。 通過 SQL瀏覽器可以對本地或遠(yuǎn)程的數(shù)據(jù)庫進(jìn)行各種 SQL查詢操作。 management system and information management system Introduction The database is stored together a collection of the relevant data, the data is structured, nonharmful or unnecessary redundancy, and for a variety of application services, data storage independent of the use of its procedures。 to achieve full sharing of data resources, and so on. In addition, the database technology also provides users with a very simple means to enable users to easily use the preparation of the database applications. Especially in recent years introduced microputer relational database management system dBASELL, intuitive operation, the use of flexible, convenient programming environment to extensive (generally 16 machine, such as IBM / PC / XT, China Great Wall 0520, and other species can run software), dataprocessing capacity strong. Database in our country are being more and more widely used, will be a powerful tool of economic management. The database is through the database management system (DBMSDATA BASE MANAGEMENT SYSTEM) software for data storage, management and use of dBASELL is a database management system software. Information management system is the use of data acquisition and transmission technology, puter work technology, database construction, multimedia technology, business needs, such as the establishment of a management platform, the platform constructed on the basis of pure software business management system (to meet the business needs for the purpose), achieving operational systems of data and information sharing, and based on this structure enquiries, scheduling or decisionmaking system. Information system can be manual or puterbased, independent or integrated, batch or online. The information system is usually the various types of bination. That is, of course, it can not be independent and 1. Independent system to meet a specific application areas (eg, personnel management) design. Independent system with its own documents, which are inevitable 2. Integrated information systems through their use of the data were bined. Resource sharing system using a database to achieve integrated objectives. For example, the normal wage system requirements from the human resources and accounting systems 3. Artificial system has been developed based on a variety of puter information systems. So far, in a puterized artificial, and still lacks design experience (or) lack of information between users and service personnel exchanges. That is to say, puterbased workflow system directly from the manual system workflow. Often, these systems are independent, and the puter just as a data processor. In the design of these systems, with little regard to their integrated to the end of intent. 4. Information systems according to a batch, online processing or both bination classification. In a batch system, and data will be handled in batches or reports. For example, banks will be a large number of cheque code, and then the end of the day, in batches of cheques, sorting and processing. Also, in order to prevent an airline ticket Talas in Atlanta and another at the same time point of sale outlets from Los Angeles to San Francisco, the last one a flight tickets, airlines must be online booking system, in order to reflect the current status of the database. Most onresources management (IRM) system, and the potential of the puter information system has been widely recognized, most of the systems is still independent batch system. Now most of these systems have lost value, but was redesigned as an integrated, online system. By definition, we c
