What is the description of urban construction archives?

Question 1: The main function of urban construction archives management system The main function of urban construction archives management system: The visual management information system of urban construction archives covers almost the whole process and most work links of urban construction archives management, expanding the application scope of urban construction archives. The main functions of the system are: 1 automatic cataloging of urban construction archives and mutual retrieval of visual images and texts. Automatic cataloging and automatic retrieval of urban construction archives are the earliest and most common application types. The main function of automatic cataloging is to automatically edit and publish the archives catalogue regularly or regularly on the basis of processing the archives machine-readable catalogue, which is an important means for the urban construction archives department to manage according to law and find urban construction archives for users in batches. Automatic retrieval is mainly to provide users with real-time online file directory retrieval service, and users can quickly find the required urban construction files. Visualization of spatial information of urban construction archives enables users to quickly find the required urban construction archives directly from the geographical location, or quickly check the spatial information content of the required building such as geographical location, distance, shape, area and neighborhood relationship from the management information of urban construction archives. 2. Storage, display and mutual retrieval of urban construction archives management information. When urban construction archives institutions have a large number of digital information storage capabilities of graphics or characters, the system can realize the storage and retrieval of the original information of urban construction archives. After scanning, urban construction archives can be stored in two ways, one is the graphic information of archives directly obtained by scanning, and the other is the text information of archives obtained by character recognition. Both methods realize the storage and retrieval of original files, but their functions are different. Graphic mode reflects the original appearance of the file, which is more suitable for handwritten or graphic file information processing. Text mode can support automatic file retrieval or text editing of words and phrases in file content. The system realizes the mutual query of spatial information, attribute information, management information and original entity information of urban construction archives. You can quickly find out all the relevant information from any kind of urban construction archives information, and realize the comprehensive utilization of urban construction archives information. 3 Urban Construction Archives Business Management The urban construction archives visualization management information system mainly realizes the management and application of the collection, collation, storage, utilization, identification and statistics of urban construction archives management business. The most important thing is to implement the standardized management of urban construction archives, and the collection methods and contents of urban construction archives and the description methods and contents of urban construction archives shall comply with the national standards or the standards of the Ministry of Construction. Under the system visual business process monitoring, we can know and master the business processing links of urban construction archives and the processing process of each file in real time. The utilization and management of urban construction archives is one of the daily operations, and the automatic borrowing management and statistics of urban construction archives are widely used in the system. The main function of the automatic lending management application of urban construction archives is to automatically manage the utilization registration, examination and approval procedures, retrieval, volume adjustment, return and utilization statistics involved in the utilization work. It can improve the management mechanism and improve work efficiency. Automatic statistics can realize the statistical analysis of the quantity, utilization, compilation and research of the collected archives, so as to evaluate the urban construction archives work. 4 Urban Construction Archives Compilation and Research and Auxiliary Decision-making The rapid query and retrieval of urban construction archives visual management information system is the most basic means of urban construction archives compilation and research auxiliary decision-making. Visual information management of urban construction archives can better analyze and extract thematic compilation information through quantitative analysis of spatial analysis and statistics, display spatial information in windows and layers, and edit and draw graphics, which can assist urban planning and urban construction decision-making. Internet Urban Construction Archives Information Using the urban construction archives visualization management information system, the spatial information, attributes and archives management information of urban construction archives can be published and queried on the Internet. As long as there is network access, you can use IE browser in the computer to query and retrieve the above-mentioned urban construction archives information, or the urban construction archives management department will release the above-mentioned urban construction archives information, so as to truly make the urban construction archives information public and the whole society. SuperMap is adopted as the development platform of network geographic information system in this system.

5. The contents of the roll box should be written completely and neatly. ......& gt& gt

Question 3: Talking about the digital management of urban construction archives utilization II. Connotation and function of new management mode.

The new management mode requires us to make changes in management ideas, management methods and management means. It is not old management plus new technology, but new management plus new technology. In our opinion, the new management mode should be a management mode that takes the archival entity and its related information as the management object, adopts the integrated management method of documents, archives and information, realizes the multifunctional development and utilization of archival information by using modern high technology, and effectively protects archival entities. The new management mode is a diversified parallel mode, which is not only the parallel of traditional archives and digital archives, but also the parallel of archival entities and information, and the parallel of traditional archives carriers and electronic carriers.

The new management mode will adopt modern high-tech and digital information processing technology, optimize the collection, arrangement and utilization of urban construction archives, realize the rational allocation of urban construction archives resources, actively construct the strategy and environment of urban construction archives resources, accelerate the innovation of urban construction archives service mechanism, provide the society with brand-new ways of urban construction archives information dissemination and exchange and high-quality urban construction archives information products, and make urban construction archives work better serve the urban modernization.

The new management mode will realize automation through management means, improve work efficiency and simplify work procedures; By digitizing management content, integrating archival information, optimizing information sources, standardizing business work, maximizing the development and utilization of archival information resources and protecting archival entities; Through service networking, we can adapt to market demand and realize resource sharing.

Third, exploration and practice:

Since 2000, Tianjin Urban Construction Archives began to explore and think about this management mode, and made the following attempts.

1. According to laws and standards, the front-end control of different types of urban construction archives entities and information reception is implemented in various ways.

Archives reception is the source of archives management, and the implementation of the new management model must also start from the source and establish the principle that both entities and information are received into the library. In 2000, Tianjin Planning and Land Resources Bureau issued the Provisions on Strengthening the Archives Management of Urban Construction Projects in Tianjin with Document No.250, and implemented the construction project archives registration system in the whole city. In 2000, the Urban Construction Archives Management Office was established, which endowed us with the function of managing the urban construction archives in the whole city and the right of administration according to law. On July 29th, 2003, Tianjin * * * promulgated the Regulations on the Management of Urban Construction Archives in Tianjin by Order No.5, which clearly stipulated the registration, planning, acceptance and filing of new projects, and incorporated them into the planning management procedure as one of the conditions of administrative licensing. In 2004, Tanggu Urban Construction Archives was established, which took an important step to form the city's urban construction archives management network with the municipal urban construction archives as the core. From the aspects of legal system construction and administrative system, the channel of receiving files into the library is fully guaranteed.

In 2004, our library undertook and completed the Rules for Filing and Arrangement of Construction Project Documents issued by the Municipal Construction Committee. For the first time, in the form of local standards, the information description of construction projects, municipal projects and underground pipeline projects, as well as related photos and video files, are included in the requirements of the construction unit for filing and sorting. It is clear that archival entities and archival information must enter the library at the same time, which makes the implementation of the new model have standards to follow from the source.

The traditional paper file management is to file in kind. It adopts the idea of "ex post facto control" and the method of "business guidance" to guide its management. This passive guidance is effective for physical documents, but with the increasing number of electronic documents, the management of front-end control has become a development trend. "Front-end control is an important content of modern document management concept. He attached measures to ensure the reliability, integrity, security and readability of electronic documents to the process of document formation. Based on the overall planning of the whole life cycle of electronic documents, we will implement some repetitive work scattered in all business links in advance to reduce repetitive work and lag work and maximize work efficiency. "

At present, the implementation of front-end control, the integration of electronic files and archives, and the establishment of a remote electronic file filing system are restricted by various management systems and technical methods. It is not easy to implement this management system comprehensively and uniformly. There are two main sources of urban construction archives, one is the management archives formed by urban planning, construction and other management departments, and the other is the newly-built project archives. According to the different characteristics of the formation and management of different types of urban construction archives, our library adopts two different front-end control methods.

Editor's Note: Archival science is a discipline that explores the development law of archives, archives work and archives cause, and studies the theory, principles and methods of archives information resources management and development. The archives column of Youxue. com provides you with the reference of archives model essays, as well as the writing guidance and layout requirements of archives to solve your writing problems.

Talking about the Application of Database in Archives Management

[Abstract] This paper analyzes the present situation and shortcomings of the application of database in archives management, discusses the realization and application of archives management by using database technology, and puts forward constructive countermeasures and suggestions, and puts forward my own thinking.

[Keywords:] database file management applications

Informatization is the general trend of today's world development and an important force to promote economic and social development and change. With the rapid development of business in various units in China, it is impossible to collect, sort out, file, archive and manage archival materials in a timely and effective manner simply by manual recording. The rapid development of computer technology in recent ten years has made it possible for all units to use computer-aided management of archives. Archives informatization refers to the comprehensive application of modern information technology in archives management, as well as the development, management and utilization of archives information resources, mainly including the digitalization and networking of archives resources, the integration of archives information management and utilization, and the high enjoyment of archives information.

The Implementation Outline of National Archives Informatization Construction stipulates the short-term development goal of China's archives work, and the review and approval of National Informatization Development Strategy (2006-2020) provides a strong guarantee for archives informatization. The intervention of computer breaks the traditional management mode, and makes the original loose and complicated file management enter a new field of centralization, unification and information automation. Although the use of computer-aided file management can greatly reduce the intensity of management, improve the efficiency of management and reduce management mistakes, because the development of computer technology, especially database, is a process of gradual development and improvement, and the staff who use this technology also have a stage of gradual learning and application, there are also many problems to be solved in computer-aided file management in various units.

First, the status quo and shortcomings of database application in file management

With the continuous expansion of the business of each unit, the traditional manual file management method can no longer meet the exponential expansion of the number of files, nor can it meet the huge demand of the society for file utilization. Using file management software for computer management is the only way to improve the file service level of each unit. Manually managed paper files are transformed into digital information and enter the network, that is, from the real state of files to the virtual state, and the file information is separated from the carrier. In this sense, the network only transmits file information, and users get only copies, not the original files. Computer-aided management of archives by using database is different from the collection, sorting, filing and management of paper documents in the past. In addition to the professional quality of file management, managers also need to have a certain understanding of computer and database applications. A considerable number of archivists are aging in knowledge structure and lack of computer technology knowledge, so they can't input basic information accurately and standardly, which leads to errors, omissions and even mistakes in basic information. At the same time, because some file management software only considered the data volume and user requirements at that time, there are few data fields in the database structure, and the database capacity is small, so it is impossible to export data in a common format. When the amount of data doubles, the speed of database operation will slow down accordingly, reducing work efficiency.

Second, the application of database in file management suggestions

It is a difficult process to comprehensively improve the security level of the archives database system, which involves many aspects and requires the management department to invest a lot of manpower and material resources. Some aspects, such as the reliability of equipment, fire prevention, etc., mainly involve the issue of investment: preventing man-made conscious destruction, such as revealing passwords, computer viruses, hackers, etc. , mainly relying on management system and computer security technology. However, the archives management department itself plays a decisive role in the consistency and integrity of the database. We should mainly pay attention to the following points:

1. Adopt scientific database development mode.

The early file management software developed by structured method has poor stability, poor modifiability and poor reusability. The change of users' needs often leads to great changes in the system structure, and it takes a lot of money to realize this change. The new file management software can adopt object-oriented programming method and stipulate one or more data conversion methods, so that data can be shared among different softwares. Considering the information network ... >>

Question 9: Ask about the terms related to urban construction in audio-visual archives, and what should be paid attention to when shooting. Audio-visual archives materials for construction projects mainly refer to historical records such as photos, audio-visual recordings and videos with preservation value, which are directly formed in the process of project planning, construction and management. In order to strengthen the management of audio-visual archives of Taizhou construction project, and ensure the completeness, accuracy and systematic filing of audio-visual archives data of construction project, according to the relevant provisions of the Measures for the Administration of Taizhou Urban Construction Archives, combined with the actual situation of this Municipality, the following provisions are formulated:
