Methods and Supporting Technologies for Data Analysis

This book gives a coherent and comprehensive picture of the new developments in database systems. It offers an overview of the ways in which data has been stored, modeled, processed and analyzed, including the technical challenges for efficiency management.

The overwhelming pace of evolution in technology has made it possible to develop intelligent systems which help users in their dayly life activities. - cordingly, methods of recording, managing and analysing data have evolved from the very simple ?le systems into complex ambient supportive intelligent systems. This book arises as a compilation of methods, techniques and tools c- nected with data related issues: from modelling to analysis. A broad range of approaches such as database self-* techniques for ubiquitous environments, multimedia data, or data driven models will be reviewed. Di?erent areas of applications, in which data models conceptualize nowadays reality, starting from e-learning to electric transformers will be considered. The book is a collection of representative contributions to cover the sp- trum related to data bases, which support decision making and data mining methods as well as conceptualization. Datawarehouse technology and m- eling are presented in the ?rst chapter together with the deep review of datawarehouse techniques for supporting e-learning processes with special emphasis on data cubes, all the tools are considered in the context of imp- mentationofsoftwareapplication.Thesecondchaptercontinueswiththes- ilar technology and deals with the community data warehouse architecture.

Together with the development of information technologies the requirements for data analysis tools have grown significantly. Due to such recent advances, as ubiquitous computing or the Internet of things, data modeling, management and processing become more and more challenging tasks. Users want to get complete knowledge from big amount of data of different kinds and formats in all possible environments. Full exploitation of the knowledge hidden in huge databases is possible only if we apply efficient methods of analysis what imposes rediscovering new techniques for storage, data warehousing, querying, extracting and mining.

The book explores the field by giving a coherent and comprehensive picture of the new developments in database systems. Consequently the presented approaches give an overview of the ways in which data has been stored, modelled, processed and analysed including the technical challenges for efficiency management. Special attention has been paid into applications taking into account such domains as the Web, image retrieval, education or electricity power generation. However the provided topics can be also developed and applied in many other areas , where database support and data analysis are necessary.

The book introduces the reader to the new challenges of databases, and is expected to be of special interest of researchers and professionals engaged in their development.
