This requires the definition of the underlying integrated
information model. Using the already mentioned adaptive
information integration, data can automatically be transferred
between the sources and the data sinks. Furthermore, data can
be consolidated for analysis [20]. Such an informationcentered
approach facilitates a structured information
management that makes an integrated and efficient data
access possible, e.g. by supporting structured query
languages. Methods and tools for data analyses and
evaluation, such as Data Warehousing and OLAP (On-Line Analytical Processing), facilitate various possibilities to
manipulate and to maintain existing data [21].
