Methodological Approaches to Modeling Information Architecture of the Organization in the Conditions of Digital Economy

It is significant for businesses, especially in the digital economy, the solution of theoretical and methodological justifications and the development of practical recommendations for building an organization\u27s information architecture as a holistic description of its key strategies, related to business, information, application systems and technologies, and also their impact on the functions and business processes of an organization. The article discusses issues, related to methodological approaches to modeling an organization\u27s information architectureб using information management tools to help manage innovation in information systems (IS) and information technologies (IT). The relevance of organizational provisions to determine the way, in which a business entity\u27s business model is functionally integrated with the IS architecture is substantiated. The consideration and analysis of the use of industrial standards for describing the architecture of an organization, adopted by such institutions as the International Organization for Standardization (ISO), The Open Group, Institute of Electrical and Electronics Engineers (IEEE), etc. reveal that none of these standards is dominant and does not provide teams, responsible for the architecture development with all the tools, necessary from the methodological point of view and from the point of view of the templates, used to describe the architecture. Recommendations are given on the theoretical and methodological substantiation and construction of the information architecture of an organization as a complete description of its key strategies related to business, information, application systems and technologies, as well as their impact on the functions and business processes of an organization

Fatou's Lemma for Weakly Converging Probabilities

Fatou's lemma states under appropriate conditions that the integral of the lower limit of a sequence of functions is not greater than the lower limit of the integrals. This note describes similar inequalities when, instead of a single measure, the functions are integrated with respect to different measures that form a weakly convergent sequence
