When a system in the structure of a number of entirely separate from the database, the system includes a database collection.Database management system is a manipulation and large-scale databa

3、se management software is being used to set up, use and maintenance of the database. Its unified database management and control so as to ensure database security and integrity. Database management system users access data in the database, the database administrator through Database management syste

4、m databasemaintenance work. It provides a variety of functions, allows multiple applications and users use different methods at the same time or different time to build, modify, and asked whether the database. It allows users to easily manipulate data definition and maintenance of data security and

5、integrity, as well as the multi-user concurrency control and the restoration of the database.Using the database can bring many benefits: such as reducing data redundancy, thus saving the data storage space; to achieve full sharing of data resources, and so on. In addition, the database technology al

The information system is usually the various types of combination.That is, of course, it can not be independent and is integrated.1 、 I

Forexample, the normal wage system requirements from the human resources andaccounting systems found in the data.3、 Artificialsystem has been developed based on a variety of computerinformation systems. So far, in a computerized artificial, and still

13、 lacks design experience (or) lack of information between users and service personnel exchanges. That is to say, computer-based workflow system directly from the manual system workflow. Often, these systems are independent, and the computer just as a data processor. In the design of these systems, w

14、ith little regard to their integrated to the end of intent.4 、 Information systems according to a batch, on-line processing or both combination 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

15、of the day, in batches of cheques, sorting and processing. Also, in order to prevent an airline ticket agent 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 on-line booking system, in order to reflect th

Most on-line information system is successful batch requirements. even if the information resources management (IRM) system, and the potential of the computer information system has been widely recognized, most of the systems is still independent batch system. Now m

17、ost of these systems have lost value, but was re-designed as an integrated, online system. By definition, we can see the comprehensive requirements of business managers and company leaders closer cooperation. Information services professionals as consultants, and the integrated information system an

Resolve these differences in order to achieve a comprehensive environmental information services staff to the challenges posed by the user manager.中文譯文數(shù)據(jù)庫信息管理系統(tǒng)簡介數(shù)據(jù)庫是存儲在一起的相關(guān)數(shù)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)

19、據(jù)的存儲獨立于使用它的程序； 對數(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。 當(dāng)某個系統(tǒng)中存在結(jié)構(gòu)上完全分開的若干個數(shù)據(jù)庫時，則該系統(tǒng)包含一個 “數(shù)據(jù)庫集合 ”。數(shù)據(jù)庫管理系統(tǒng) (database management system)是一種操縱和管理數(shù)據(jù)庫的大型軟件，是用于建立、使用和維護(hù)數(shù)據(jù)庫，簡稱dbms。它對數(shù)據(jù)庫進(jìn)行統(tǒng)一的管理和控制，以保證數(shù)據(jù)庫的安全性和完整性。用戶通過 dbms 訪問數(shù)據(jù)庫中的數(shù)據(jù)，數(shù)據(jù)庫管理員也通過 dbms 進(jìn)行數(shù)據(jù)庫的維護(hù)工作。它提供多種功能，可使多個應(yīng)用程序和用戶用不同的方法在同時或不同時刻去建立， 修改和詢問數(shù)據(jù)庫。它使用戶能方

20、便地定義和操縱數(shù)據(jù)， 維護(hù)數(shù)據(jù)的安全性和完整性， 以及進(jìn)行多用戶下的并發(fā)控制和恢復(fù)數(shù)據(jù)庫。使用數(shù)據(jù)庫可以帶來許多好處： 如減少了數(shù)據(jù)的冗余度， 從而大大地節(jié)省了數(shù)據(jù)的存儲空間； 實現(xiàn)數(shù)據(jù)資源的充分共享等等。 此外，數(shù)據(jù)庫技術(shù)還為用戶提供了非常簡便的使用手段使用戶易于編寫有關(guān)數(shù)據(jù)庫應(yīng)用程序。 特別是近年來推出的微型計算機(jī)關(guān)系數(shù)據(jù)庫管理系統(tǒng)，操作直觀，使用靈活，編程方便，環(huán)境適應(yīng)廣泛 (一般的十六位機(jī)，如 IBM/PC/XT ，國產(chǎn)長城 0520 等均可運(yùn)行種軟件 )，數(shù)據(jù)處理能力極強(qiáng)。 數(shù)據(jù)庫在我國正得到愈來愈廣泛的應(yīng)用， 必將成為經(jīng)濟(jì)管理的有力工具。數(shù)據(jù) 庫 是通 過數(shù) 據(jù)庫 管理 系 統(tǒng) (DBMS-DATA BASE MANAGEMENT SYSTEM) 軟件來實現(xiàn)數(shù)據(jù)的存儲、管理與使用的微型計算機(jī)關(guān)系數(shù)據(jù)庫管理系統(tǒng)就是一種數(shù)據(jù)庫管理系統(tǒng)軟件。信息管理系統(tǒng)是利用數(shù)據(jù)采集與傳輸技術(shù)、計算機(jī)網(wǎng)絡(luò)技術(shù)、數(shù)據(jù)庫建設(shè)、多媒體技術(shù)、業(yè)務(wù)需求等建立一個管理平臺，在平臺的基礎(chǔ)上構(gòu)建的純軟件業(yè)務(wù)管理系統(tǒng)（以滿足業(yè)務(wù)需求為目的） ，實現(xiàn)各業(yè)務(wù)系統(tǒng)之間的數(shù)據(jù)和信息共享，并在此基礎(chǔ)上搭建查詢、調(diào)度或者輔助決策系統(tǒng)。信息系統(tǒng)可以是人工的或基于計算機(jī)的，獨立的或綜合的， 成批處理的或聯(lián)機(jī)的。通常的信息系統(tǒng)是上述各種類型的組合。當(dāng)然它不能即是獨立的又是綜合的。1、獨立的系統(tǒng)是為了滿足某個特定的應(yīng)用領(lǐng)域
