What is the database used in microcomputers?

The database used in microcomputers belongs to "computer applications in data processing". Data processing is currently the most widely used field of computer applications. Data processing is inseparable from the support of software. Data processing software includes: various programming languages ​​and their compilers used to write processing programs, file systems and database systems for managing data, As well as application software packages for various data processing methods; the database can automatically manage large amounts of data and improve the efficiency of computer use.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

The database used in microcomputers belongs to "computer applications in data processing".

Data processing, data processing is the basic link of system engineering and automatic control. Data processing runs through all areas of social production and social life. The development of data processing technology and the breadth and depth of its application have greatly affected the development process of human society.

The basic purpose of data processing is to extract and deduce valuable and meaningful data for certain people from a large amount of data that may be messy and difficult to understand.

Data processing cannot be separated from the support of software. Data processing software includes: various programming languages ​​​​and their compilers used to write processing programs, file systems and database systems for managing data, and various data processing Method application package. In order to ensure data security and reliability, there is also a set of data security and confidentiality technologies.

Among them, the database automatically manages a large amount of data and improves the efficiency of computer use.

Data processing is a technical process for analyzing and processing data (including numerical and non-numeric). Including the processing and processing of analysis, sorting, calculation, editing, etc. of various raw data. It has broader meaning than data analysis. With the increasing popularity of computers, numerical calculations account for a small proportion in the field of computer applications, and information management through computer data processing has become the main application. Such as surveying and mapping management, warehouse management, accounting management, transportation management, technical information management, office automation, etc. In terms of geographical data, there are both a large amount of natural environment data (land, water, climate, biological and other resource data) and a large amount of socioeconomic data (population, transportation, industry and agriculture, etc.), which often require comprehensive data processing. Therefore, it is necessary to establish a geographical database, systematically organize and store geographical data to reduce redundancy, develop data processing software, and make full use of database technology for data management and processing.

Expand knowledge:

Data processing has gone through three stages of development from simple to complex, they are:

①Electronic Data Processing (EDP)

It uses the file system as a means to achieve individual management within a department.

② Management Information System (MIS)

uses database technology as a tool to achieve comprehensive management of a department to improve work efficiency.

③Decision Support System (DSS)

It is based on database, model library and method library to help management decision-makers improve their decision-making level and improve the correctness of operational strategies. sex and effectiveness.

At present, data processing has been widely used in office automation, computer-aided management and decision-making in enterprises and institutions, information retrieval, library management, film and television animation design, accounting computerization and other industries. Information is forming an independent industry. Multimedia technology allows information to be displayed in front of people not only in numbers and text, but also in emotive sounds and image information.
