data-processing system
In data processing, computer hardware equipment is a necessary condition and a guarantee for fast data processing. In order to meet the needs of large-scale data processing, national data processing and statistics should be carried out in the form of local area network or multi-level local area network.
General data processing can be carried out by centralized data storage, which is suitable for data processing with moderate data volume in original data concentration, and its structure management is convenient and easy to control. This network structure can be used for most data processing. In the case of large amount of data, scattered original data and many work stations (such as census), multi-level LAN structure is adopted.
The software platform of data processing system mainly includes operating system and database. The choice of operating system and database is mainly based on the scale and security requirements of specific data processing projects, as well as the familiarity of users with the selected software, the limitations of existing hardware equipment and the price of software. Users can choose the appropriate operating system and database system according to their own needs.
