Secondary input verification method: the same batch of data is input twice, or input by two operators respectively, and then checked by the computer one by one. If it is inconsistent, it will be rejected and forced to modify. This input data verification method is called secondary input verification method.
Static inspection method: Static inspection is also called "manual inspection". Before entering accounting data, the operator should check the accounting voucher data item by item.
Balance inspection method: the balance operation of assembled rotating machinery in the field installation state is called overall field balance. In this method, the machine, as the basis of dynamic balance, processes the data through the vibration information of the related parts of the rotor measured by the sensor, so as to determine the unbalance amount and its orientation on each balance surface of the rotor, and eliminate the unbalance by removing weight or adding weight, thus achieving the purpose of high-precision balance.
There are also file query verification method, boundary verification method, data format verification method, check code method and so on.
Extended data:
Management information system is a human-centered system that uses computer hardware, software, network communication equipment and other office equipment to collect, transmit, process, store, update, expand and maintain information.
Management information consists of six aspects: information collection, information transmission, information storage, information processing, information maintenance and information utilization.
A perfect management information system (MIS) has the following four standards: clear information demand, information acquisition and processing, providing information for managers through procedures and management information.
Unified planning database is an important symbol of the maturity of management information system, which indicates that management information system is the product of software engineering. Management information system is an interdisciplinary comprehensive discipline, which is composed of computer disciplines (network communication, database, computer language, etc.). ), mathematics (statistics, operational research, linear programming, etc. ), management, simulation and other disciplines.
Information is an extremely important resource in management. The success or failure of management depends on whether effective decisions can be made, and the correctness of decisions depends largely on the quality of information. Therefore, whether information can be effectively managed has become the primary problem faced by enterprises. In the modern society that emphasizes management and information, management information systems are becoming more and more popular.
