Data quality assurance in state information systems
To improve the quality information support for state management, a lot of specially integrated information systems are being developed to the control of the Russian Federation specific departments and ministries. This systems purpose is complex automation of all levels activities of government and providing information interaction with each other and external objects. The research urgency is due to the complexity of state information systems performance, the increasing necessity in data reliability, the widening range ofaudits carried outto ensure control at all stages ofthe data flow. This is especially true of data coming from different sources that have an ambiguous degree of verification. Note that the developed system is constantly expanding, in the new services forms and mobile versions. This process is aimed at increasing level of data openness, their availability to the population and processes transparency for obtaining them. Conducting an analytical study of the use of various parameters for state information systems data quality assessment will allow us to identify proposals for data quality control. In this article, author presents the parameters to specify the data quality in Ishikawa diagram, and the aspects formalization of state information systems data quality assurance processes. Recommendations have been given for further usage by system analysts, IT specialists in the development of complex information systems.
