Abstract: In multi-version data warehouse，schema evolution brings new data warehouse versions.Directly designing the schema evolution manipulation to implement version evolution may cause redundance of arithmetic code and several same version objects.The paper designs evolution meta-operations to realize the versions evolution，presents a formal definition of data warehouse version and the definitions of three kinds of meta-operations based on version objects，and then illustrates the arithmetic ideas to realize version evolution by executing meta-operations.The design of meta-operations reduces the complexity of version evolution algorithmic and benefits the management of versions.

Key words: data warehouse version, schema evolution, version evolution, meta-operation
