The paper considers issues of data migration from corporate information systems of clients for localizing defects on the developer’s side. The main revealed problem is the defects localization on the client side. As a solution, an approach to data banks processing is proposed. The approach is based on the defect data exchange method and the defect presentation model. The paper describes an information flows model of a corporate system in the context of the detected defects layer (data cast). The main task of data banks processing in defect localization is determined. It is the selection of data cast for a specified time period. A defect model is proposed in the form of a parameters set for data selection, which is built on the metadata concept. The model is defined as a tuple of data records from a set of interrelated entity tables for some time period. Thus, application of the proposed approach will automate the data migration process between client and developer systems and, in general, will increase the efficiency of corporate information systems support by reducing the processed and sent information. The results of a computer experiment showed that the data volume during the migration process significantly decreased. To approach will improve the efficiency of maintaining corporate systems by reducing the processed and transmitted information. Potentially, this model can be applied in the inverse problem – to migrate data from the developer’s side to the client. It is supposed to carry out processing on a database of any size and structure.

Abstract. Digitalization, enhanced storage capacities, and the Internet of Things increase the volume of data in modern organizations. To process and make use of these data and to avoid information overload, management information systems (MIS) are introduced that collect, process, and analyze relevant data. However, a precondition for the application of MIS is that users trust them. Extending accounts of trust in automation and trust in technology, we introduce a new model of trust in MIS that addresses the conceptual ambiguities of existing conceptualizations of trust and integrates initial empirical work in this field. In doing so, we differentiate between perceived trustworthiness of an MIS, experienced trust in an MIS, intentions to use an MIS, and actual use of an MIS. Moreover, we consider users’ perceived risks and contextual factors (e. g., autonomy at work) as moderators. The introduced model offers guidelines for future research and initial suggestions to foster trust-based MIS use.
