Using computers for census is a "data processing" application of computers. Data processing refers to the collective term for a series of activities such as collecting, storing, sorting, classifying, counting, processing, utilizing, and disseminating various data; the basic purpose of data processing is to extract data from a large amount of data that may be messy and difficult to understand. Extract and derive valuable and meaningful data for certain people.

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

Using computers for census is a "data processing" application of computers.

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.

Data (Data) is an expression of facts, concepts or instructions, which can be processed by manual or automated devices. When data is interpreted and given a meaning, it becomes information. Data processing is the collection, storage, retrieval, processing, transformation and transmission of data.

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 that manage data

  • Application software packages for various data processing methods.

    In order to ensure data security and reliability, there is also a set of data security and confidentiality technologies.

Computer data processing mainly includes 8 aspects

①Data collection: Collect the required information.

②Data conversion: Convert information into a form that the machine can receive.

③Data grouping: Specify the encoding and perform effective grouping according to relevant information.

④Data organization: Organize data or arrange data in some way for processing.

⑤Data calculation: Perform various arithmetic and logical operations to obtain further information.

⑥Data storage: Save the original data or calculated results for later use.

⑦Data retrieval: Find useful information according to user requirements.

⑧Data sorting: Arrange the data in order according to certain requirements.

The data processing process is roughly divided into three stages: data preparation, processing and output. During the data preparation phase, data is input offline to punched cards, punched paper tape, tape, or disk. This stage can also be called the data entry stage. After the data is entered, the data must be processed by the computer. For this purpose, the user must prepare a program in advance and input the program into the computer. The computer processes the data according to the instructions and requirements of the program. The so-called processing refers to one or a combination of several of the above eight aspects of work. The final output is various text and numerical tables and reports.

Data processing systems have been widely used in various enterprises and undertakings, covering salary payment, bill sending and receiving, credit and inventory management, production scheduling, plan management, sales analysis, etc. It can generate operational reports, financial analysis reports, statistical reports, etc. Data processing technology involves technologies such as document systems, database management systems, and distributed data processing systems.

In addition, due to the large amount of data or information used in various enterprises and institutions, an independent information processing industry has been formed in the industrialized society. Data and information themselves have become extremely valuable resources in human society. The information processing industry organizes and develops these resources to promote the development of the information society.

Expand knowledge:

Computer application fields include: scientific computing, data processing, computer network and communications, process control, computer-aided systems, Artificial intelligence, office automation field, auxiliary engineering.
