Numerous nowadays applications generate huge sets of data, whose natural feature is order, e.g,. sensor installations, RFID devices, workflow systems, Website monitors, health care applications. By analyzing the data and their order dependencies one

Ubiquitous devices and applications generate data that are naturally ordered by time. Thus elementary data items can form sequences. The most popular way of analyzing sequences is searching for patterns. To this end, sequential pattern discovery tech

Ubiquitous devices and applications generate data, whose natural feature is order. Most of the commercial software and research prototypes for data analytics allow to analyze set oriented data, neglecting their order. However, by analyzing both data

Recent appearance of the a type of OLAP analysis, the sequential OLAP (or SOLAP) has caused the need for new index structures which support new types of analytical queries. An integral part of processing SOLAP queries is finding sequences which match

Nowadays business intelligence technologies allow to analyze mainly set oriented data, without considering order dependencies between data. Few approaches to analyzing data of sequential order have been proposed so far. Nonetheless, for storing and m

In this paper we address problems of managing data warehouses (DWs) that evolve in time and we demonstrate that transactional maintenance of evolving DWs is inevitable. To this end, we propose a nested transaction model. In this model we define 5 typ

A data warehouse (DW) is supplied with data that come from external data sources (EDSs) that are production systems. EDSs, which are usually autonomous, often change not only their contents but also their structures. The evolution of external data so

Object-relational data warehousing systems are more and more often applied to the integration and analysis of complex data. For such warehouses, the application of materialized object-oriented views is promising. Such views are able to: (1) integrate

In several database applications sets of related queries are submitted together to be processed as a single unit. In all these cases the queries usually have some degree of overlap, i.e. may have common subqueries. Therefore a significant performance
