datebase

 When people from different perspectives to describe the concept, there are different definitions (of course, descriptive). For example, saying that the database is a "record-keeping system" (the definition emphasized the database is a collection of a number of records). Another example is that the database is "people to solve specific tasks to a certain degree of organization is stored together a collection of related data" (This definition focuses on the data organization). Even worse, said the database is "a data warehouse." Of course, this argument although the image, but not rigorous.
Strictly speaking, the database is "in accordance with the data structure to organize, store and manage data warehouses." In the economic management of the daily work, often need to put some data related to such a "warehouse", and according to the management of the need for appropriate treatment. For example, enterprises or institutions of the personnel department is often necessary to the basic situation of workers in this unit (employee number, name, age, gender, place of origin, wages, resume, etc.) stored in the table, this table can be viewed as a database . With this "data warehouse" as needed at any time we can check the basic situation of a trade union can also access a range of wages in the number of workers and so on. If this work can be automatically on the computer, then we are in personnel management can be very high level. In addition, financial management, warehouse management, production management also need to build a large number of such "database" so that it can use the computer to achieve financial, warehouse, production automation.
J. Martin to the database, itself a relatively complete definition: database is stored a collection of related data together, these data are structured, non-harmful or unnecessary redundancy, and for a variety of application services; data Storage is independent of the use of its procedures; insert new data to the database, modify and retrieve the original data can by a common and controlled manner. When a system exists in the structure of a number of completely separate database, then the system contains a "database collection."
