The so-called digitization refers to the process of converting analog signals into digital signals by computer technology. Digitization of paper files is the process of digitally processing paper files using digital devices such as scanners or digital cameras, and converting them into digital images or digital texts that are stored on tapes, disks, optical disks, etc., and can be recognized by computers. . The basic principle of digitalization of paper archives is to make archived information resources available accurately, conveniently and quickly, so that open archived information resources can be shared to meet the needs of social or industry use of archives.
1. Basic principles of digital processing of archives
1) Identify digital objects
The objects to be digitized should be confirmed according to certain principles and methods. Only paper archives that meet certain requirements can be digitally processed.
2) In line with national laws and regulations
The digitization of paper files must comply with the national archives opening regulations or relevant regulations of the industry.
3) Value principle
Archives that are archived and that should be stored permanently or permanently for a long time, can be included in the scope of digital processing.
2, digital processing flow
The basic links of digital processing of paper files mainly include: file sorting, file scanning, image processing, image storage, directory building, data hooking, data acceptance, data backup, results management, etc. The processing flow is as follows:
3. The goal of digital construction
The goal of digital construction is to realize the digital processing of the existing archives and documents of the archives (room), establish a sound archive directory database, the current document full-text database and multimedia database (photo, audio, video, etc.), through the data interface and government office The system is connected, and the advanced digital file management system provides safe and efficient management and utilization to realize real resource sharing.
4, the meaning of digital
1) Improve work efficiency and reduce file utilization costs
After the completion of the digital processing project, the leaders of the public (open archives) and the units, departments or subordinate units can use the digital file management system to instantly query and use the original text information of the electronic document data, avoiding the traditional files. The use of methods for the large amount of time waste and duplication of labor caused by the multiple transfer of archives and data entities, thereby improving work efficiency and reducing the cost of archival information utilization.
2) Maximum storage and protection of inventory file entity security
Since the traditional file storage method has always adopted paper storage and catalog management, it not only occupies a large amount of inventory space, but also needs to go to the warehouse, the management cost is high, and the file is easily damaged, such as yellow, sticky, and brittle paper. Therefore, directory-level file management cannot fundamentally solve the problem that the original file is vulnerable. The digital management of the file can be directly checked and printed on the Internet through the authority control, which reduces the number of times of reading and copying the inventory file, reduces the aging speed of the inventory file, and solves the contradiction between the repeated use of the file and the file storage, so that it can be the largest. Limit the effective storage and protection of inventory files to ensure the security of the archives.
3) Sunshine government to enhance the image
The realization of digital and electronic management of inventory archives is not only a major event for the archives management departments at all levels to implement the scientific development concept, the implementation of the 11th Five-Year Plan for the national archives undertaking, but also a concrete measure to promote the informationization and modernization of archives management; Need, is also a highlight project. It is a matter of great significance to the benefit of the country and the people. After the completion of the digital project, not only the file management and utilization means have been modernized, the efficiency of file utilization has been greatly improved, the role of the archives has been played significantly, and the image of the unit has been greatly enhanced, which is in line with the scientific, standardized and networked work of the government, enterprises and institutions. The overall development requirements of information technology.
