Schema integration: There are many approaches to schema integration which are candidate algorithms for Match [BCV99, JMN 99, MHH00, MWK00, PSU98, MMP95, DDL00] ....

Additionally, functions for non contiguous structure versions can be de ned or derived to optimize performance. 7 Related Work In contrast to temporal databases, which have been well studied, e.g. 3, 7, 8] few approaches are known in literature for temporal data warehouses, e.g. [4, 13 15]. The same applies for schema evolution of databases, e.g. 13, 5] vs. schema evolution of data warehouses, e.g. 2] 4] present which extensions are necessary in order to extend a data warehouse to cover temporal aspects, in particular they keep track of the history of hierarchical ....

....and represented using a solid rectangle (G 1 ) and edge (G 3 ) respectively. The derivation of the new schema from the old one can be depicted by using a directed parallel line (G 9 ) which goes from V 0 2 to V 3 . More examples of the use of EVER diagrams to capture schema changes are shown in [11]. Thus far, we have discussed how EVER diagrams can capture all the aspects involved in the evolution of the schema of a database that does not support class hierarchies. Before considering schema evolution that involves class hierarchy and inheritance, in the next section we will show how EVER ....
