Preface to ECDM 2008
Change is a fundamental but sometimes neglected aspect of information and database systems. The management of evolution and change and the ability for database, information and knowledge-based systems to deal with change is an essential component in developing and maintaining truly useful systems. Many approaches to handling evolution and change have been proposed in various areas of data management and this forum seeks to bring together researchers and practitioners from both more established areas and those from emerging areas to look at this issue. The fifth ECDM workshop (the first four ECDM workshops were held with ER’99 in Paris, France, with ER’02 in Tampere, Finland, with ER’04 in Shanghai, China, and with ER’06 in Tucson, Arizona) deals with the manner in which change can be handled, and the semantics of evolving data and data structure in computer based systems, including databases, data warehouses and Web-based information systems.
