When people from different perspectives to describe the concept has a different definition (of course, are descriptive). For example, saying the database is a "record-keeping system" (emphasis in the definition of the database is a collection of a number of records). Another example is the database that are "people to solve specific tasks, must be organized in a manner so as to store with a collection of relevant data" (the definition of focus on data organization). Even worse, said the database is "a data warehouse." Of course, this argument although the image, but not strict.
Strictly speaking, the database is "in accordance with the data structure to organize, store and manage data warehouses." In the economic management of their daily work, usually need to put some relevant data in such a "warehouse", and in accordance with management's need for appropriate treatment. For example, enterprises or institutions usually the personnel department to the basic conditions of employees (No. of workers, name, age, sex, native place, wages, curriculum vitae, etc.) stored in the table, this table can be seen as a database . With this "data warehouse" we can at any time necessary inquiries in accordance with the basic situation of a trade union, but also can search for wages at a certain number of employees within the scope of and so on. If these tasks can be automated in the computer on, and that U.S. personnel management can achieve very high levels. In addition, financial management, warehouse management, proction management is also necessary to establish a large number of such "database" so that it can make use of the computer implementation of financial, warehouse, proction automation management.
J. Martin to the database under a relatively complete definition: database are stored together a collection of relevant data, the data are structured, non-harmful or unnecessary rendancy, and for a variety of applications services; data storage independent of the use of its proceres; on the database to insert new data, modify and retrieve the original data were in accordance with a common and controlled manner. When a system structures exist on the number of completely separate database, the system contains a "database collection."
The main features of the database
(1) data sharing implementation.
Sharing of data includes all users can simultaneously access the data in the database, users can also include a variety of ways using the database through the interface and to provide data sharing.
(2) to rece data rendancy.
Compared with the file system, because of the database implementation of data sharing, thus avoiding the user set up their own application files. Substantial rection of plicate data, reced data rendancy, maintain data consistency.
(3) data independence.
The independence of data, including database logical structure of databases and applications independent of each other, but also physical changes in the structure of the data does not affect the logical structure of data.
(4) centralized control of data implementation.
Document management approach, the data in a decentralized status, different users or the same user at different treatment of no relation between their document. Use of the database, the data centralized control and management, and data model that the organization of various data and data linkages.
(5) data consistency and maintainability, to ensure data security and reliability.
Mainly include: ① security control: in order to prevent data loss, error updating and the use of ultra vires; ② the integrity of control: to ensure data accuracy, effectiveness and compatibility; ③ Concurrency Control: To enable at the same time period, allowing for achieve multiple access data, but also prevent users from abnormal interaction between; ④ fault discovery and recovery: from the database management system to provide a method to detect faults and repair, thereby preventing destruction of data

Little reward, at Sina love me question many of the points, we can go that translation, thank you.
