4. Digital currency is an alternative currency in the form of electronic currency. It is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community. It is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currencies, such as bitcoin, lightcoin and ppcoin, are electronic currencies created, issued and circulated by means of check sum cryptography

digital gold currency is a kind of electronic currency named after the weight of gold. The typical unit of measurement for this currency is the Troy gram or troy ounces, although sometimes the golden Dinar is used. Digital gold currency is funded by gold storage without quota or decentralized quota. By January 2006, digital gold currency suppliers held more than 8.6 metric tons of gold as reserves, worth about $154 million.

5. According to the state's latest regulations in 2020, trading does not violate the law, but the profits generated by the transaction do not declare personal income tax, which is tax evasion.

6. The overall framework of e-government issued by the state information leading office is of great significance to the promotion of the national overall e-government project. The introction of the document points out the direction for the further implementation of the e-government project. The document especially emphasizes the important role of the exchange and sharing of government information resources, It is clear that the construction of information resource exchange and sharing mechanism is an important support system for the overall e-government project

from the construction experience of a large number of information exchange and sharing projects, it is very important to determine the objectives of the information exchange and sharing project. All parties of the project construction should first reach a consensus on the following key issues of success:

· the problem of sharing and exchanging information service objects

· the service mode that different service objects should adopt

· storage and unified management of shared information

· scientific analysis of the sources of information

· related information technology standards and management standards

· principles for the design and construction of information exchange and sharing platform

these problems are the core problems to solve the information exchange and sharing, and are the practical problems existing in the project implementation. No matter how different the technical methods to solve the information exchange and sharing are, the real solution of these problems is the foundation and guarantee of the project construction< The significance of e-government project construction lies in that it can play a supporting role in various functions of the government, and use it technology to help the government improve work efficiency and promote the transformation of government functions. Therefore, to invest in the construction of a large-scale e-government project, first of all, it is necessary to determine its service objectives and the system construction's & quot; Theme Application & quot< br />
" The Eleventh Five Year Plan & quot; During this period, the party and the state made it clear that the establishment of & quot; Harmonious Society & quot; According to the characteristics of their own work functions, governments at all levels and functional organizations at all levels have determined the & quot; The Eleventh Five Year Plan & quot; Planning, on the premise of the overall goal, determines the goal system of each work. E-government project construction & quot; Theme application;, It is to determine the service goal of e-government project, and combine the construction goal of e-government project with the establishment of & quot; Harmonious Society & quot; It is an important part of the overall development goal of the government to link up the overall planning goal of e-government closely and clarify the overall development goal of e-government. The construction of information exchange and sharing mechanism must also face a challenge; Theme application;, A project that is divorced from the theme of service is a project without vitality

China's overall construction of a new socialist countryside, Beijing's floating population management, etc., are the key problems directly faced by different levels of government agencies. The theme application of e-government project should only focus on the most urgent problems to be solved by the government and the theme of the government's strategic objectives to carry out the construction of data exchange and sharing mechanism< The construction of information exchange and sharing mechanism is the long-term task of the overall construction of e-government, which keeps pace with the development of national economy and the process of the overall government function reform. The specific information exchange and sharing project construction must conform to the principle of practical priority and adapt to the future development. First of all, it is necessary to determine the construction objectives of specific projects, which must be established in the government agencies; Improve administrative efficiency and public service quality & quot; On the basis of the business objectives of the government, it engineering projects need to focus on the contribution to the current government function transformation project; In addition, we must fully respect the basis of practical work and the current administrative functions of the government, drive the engineering construction of the information exchange and sharing mechanism, transform the government information department into a specific actual business department, and clarify the viewpoint that the information department serves the actual business department of the government, The actual business work of the government should be closely linked with the construction of information resource sharing; According to the actual situation of different government agencies and local governments, the boundary scope of project construction is defined, the principle of project construction is determined, and the construction of long-term information sharing mechanism is well combined with the goal of single project construction; Technological innovation is prior to collaborative innovation of government business. The construction of data exchange and sharing platform needs to consider the needs of future business expansion and intensive engineering construction

3. Multi dimensional understanding of requirements

the guiding ideology of business information requirements analysis is three-dimensional system model. This is because only from the perspective of information resources, without in-depth study of the actual operation of government departments, it is difficult to do a good job in the information interaction and sharing project. We believe that government work is driven by the joint action and coordination of business management, execution driven and organizational management. Three dimensional system model is as follows:


figure: three dimensional system model

three dimensional system model composition: first, business management level, including key business system, support business system and auxiliary support system; Second, business driven mode, including target decision-making, task assignment, task decomposition, work organization, implementation and execution supervision; Three organizational forms, including the core decision-making level, work organization and implementation level and implementation level. Business information runs through the whole process of target management. Information system construction must meet the actual needs of different dimensions in order to truly reflect the strong supporting role of information resources for business

4. Information planning

the core of information planning is to establish a data supply chain for theme oriented applications, which needs to solve the problems of sharing and exchanging information, how to obtain from there, how to manage effectively, how to provide services to business systems, and form a clear chain of data proction, data processing and management, and data services. Information planning is built on the basis of data analysis, is a deeper analysis of exchange and sharing of information, is the top-level design of technology to achieve exchange and sharing of information

based on the guidance of information engineering methodology (IEM), using engineering method to plan information for information exchange and sharing is to follow certain method steps, follow certain standards and specifications, use effective tools to analyze information demand and data flow of various functional areas, and formulate basic standards for information resource management, Establish the information system framework of sharing domain and each functional domain

generally speaking, the content of information includes system analysis oriented to functional domain, data flow model, and topic library conceptual model oriented to shared domain. The specific content of information planning varies with the elements of a specific project. Information resource planning of information exchange and sharing construction emphasizes the close combination of information sharing requirement analysis and system modeling -- requirement analysis is the preparation of system modeling, and system modeling is the qualitative and standardized expression of information exchange and sharing construction. In the information planning of information exchange and sharing construction, we first determine the strategic construction objectives of specific projects, determine the work objectives of collaborative government agencies around the strategic objectives, and determine the work objectives according to the tasks of different organizations; Functional areas & quot;; Then, the business flow and data flow of each functional domain are investigated and analyzed, and the data flow model and data model for information exchange and sharing are established as the data basis for the construction of the whole information exchange and sharing platform

5. Shared data storage management

2. Basic database of legal entities

build basic information database and query service system of legal entities with organization code as the unique identification, realize the information sharing of legal entities among e-government business systems, and provide services to the society< According to the needs of national macro-control decision-making, social micro management, people's life and opening to the outside world, we should establish a scientific, authentic and comparable macroeconomic database. The index system of macroeconomic database not only has clear boundary, but also covers the macro situation of national economy, social development, science and technology ecation, environmental resources and so on. Macroeconomic database will become a comprehensive information channel of macroeconomic basic situation and development trend< 4. Basic database of natural resources and spatial geography

the basic information database of natural resources such as hydrology, mineral resources, land, forest, cultivated land and ocean has been basically built, forming a mechanism of exchange and sharing of basic resource information database. The basic information database of spatial geography should be constructed at different levels to form the mechanism of spatial geographic information exchange and sharing. It provides realistic simulation maps and decision support services for macro decision-making of governments and departments at all levels, overall urban planning, land use planning, land management, water conservancy planning, mineral resources planning, mining right management, geological environment management, road construction, environmental protection, etc<

subject information database

subject database is established according to the requirements of information resource planning and basic database

there are frequently used business data, which can be stored in the data center, but a large number of them are stored in the form of directory, and the data is always stored in each bureau, which not only ensures the consistency of the dynamic update of the data, but also ensures the security of the data. The data of subject oriented operational database comes from XML documents and information in the process of data exchange. Therefore, operational database must have good support for XML standards to ensure the efficiency and accuracy of information storage, exchange and retrieval

decision information base

on the basis of sufficient data sources, it can acquire, express, manage and apply distributed and heterogeneous knowledge sources. The whole system should support a variety of knowledge expression methods and reasoning methods, support the coexistence of structured data and unstructured data, and establish DSS; Data & quot; As a numerical value, it is transferred to DSS supporting the establishment of basic documents. It is necessary to integrate DW, DM, OLAP and other KDD knowledge acquisition methods to integrate all kinds of distributed and heterogeneous knowledge sources to provide various types of effective data analysis for decision makers and play the role of decision support<

other databases

data and document library: data and documents mainly include the instructions of national policies, relevant data and articles, etc., which are the basis for staff at all levels to handle various businesses, as well as the basis for learning national and municipal policies and laws

7. As for whether we can wear a watch in the environment of swimming and sauna, [ruizuan Tianjin famous watch customer service center] we must make clear the following concept: Waterproof within 50 meters belongs to ordinary waterproof, which means that the surface of the watch contacts with water without any water pressure on it, and can only be used in daily water (cold water) or rain. Only professional waterproof meters over 100 meters can be used for underwater work such as swimming or diving. Any waterproof watch should not be worn in hot water bath, sauna or in the environment with great temperature change. When the temperature drop is large, the waterproof rubber ring will expand and contract with heat, and its expansion coefficient is more sensitive than the watch case e to the change of temperature difference. Therefore, when the temperature changes, the gap between the waterproof ring and the watch case, that is, the void into which water and gas can drill, appears. In the long run, the elasticity of the waterproof ring will be reced and the aging will be accelerated, which will lead to the phenomenon of water inflow and water condensation in the meter. In serious cases, the parts of the movement will be damaged
