In mid April, the reporter witnessed the "one click" convenient operation of accessing archives at the Militia Archives Room of the People's Armed Forces Department in Nanchang County, Jiangxi Province, by entering a name or number, clicking the mouse, and the system automatically tracks the target file and flashes reminders. The militia archives have been moved from the 'paper room' to the 'fingertips', providing basic data support for the entire militia group in the new year Tu Qingsong, a staff officer of the People's Armed Forces Department of Nanchang County, introduced that the militia file retrieval and management system built using big data technology can quickly complete the search for files, screen out militia that meet the conditions for the new year's militia group, and adjust those who do not meet the conditions out of the team, greatly improving the efficiency of the entire group. Accurate troop formation is supported by technology, and scientific planning and layout are also important The person in charge of the militia group work in Nanchang Garrison District introduced that they have scientifically planned and laid out the militia group work based on the uneven distribution of resources in emerging fields in various counties (cities, districts) through databases established in various industries to understand talent distribution, professional expertise, and other situations. They follow the principle of "party members first, retired soldiers first, and those with professional and technical expertise first", and increase the staffing of specialized, refined, special, and new specialties with relatively concentrated industry advantages in their jurisdiction. They also adjust the task of militia formation for areas lacking professional resources. For example, in the formation process of the militia meteorological and hydrological observation team, they select personnel with professional skills such as meteorological observation, forecasting, and hydrological monitoring based on the potential database of relevant industry fields, and then scientifically organize them according to task requirements and personnel professional levels. In order to keep the data "fresh", Nanchang Garrison District organized personnel to conduct in-depth on-site inspections, comprehensively surveyed personnel who meet the conditions for military deployment in towns (streets) and villages (communities), dynamically updated the database by professional categories, and ensured the accuracy of the data. Efficient screening, scientific selection of troops, and precise formation of troops... The innovative practice of using big data to assist in the work of militia formation has optimized the structure of the militia team, improved the quality of militia formation, and laid a solid foundation for the execution of support and guarantee tasks.
