    ABSTRACT: Though in most data warehousing applications no relevance is given to the time when events are recorded, some domains call for a dif- ferent behavior. In particular, whenever late registrations of events take place, and particularly when the events registered are subject to further updates, the traditional design solutions fail in preserving accountability and query consistency. In this paper we discuss the alternative design solutions that can be adopted, in presence of late registrations, to sup- port different types of queries that enable meaningful historical analysis. These solutions are based on the enforcement of the distinction between transaction time and valid time within the model that represents the fact of interest. In particular, we show how late registrations can be dif- ferently supported depending on the flow or stock semantics given to events.

    ABSTRACT: This article discusses the challenges for Database Management in the Internet of Things. We provide -scenarios to illustrate the new world that will be produced by the Internet of Things, where physical objects are fully integrated into the information highway. We discuss the different types of data that will be part of the Internet of Things. These include identification, positional, environmental, historical, and descriptive data. We consider the challenges brought by the need to manage vast quantities of data across heterogeneous systems. In particular, we consider the areas of querying, indexing, process modeling, transaction handling, and integration of heterogeneous systems. We refer to the earlier work that might provide solutions for these challenges. Finally we discuss a road map for the Internet of Things and respective technical priorities.
