摘要： In accordance with one embodiment of the present invention, there is provided a technique for dynamically pipelined data migration. According to one aspect, it is determined that a source schema-conformant source data set is to be converted to a target schema-conformant target data set. A plurality of conversion mechanisms, which can be invoked in succession to convert the source data set into the target data set, is automatically determined. The plurality of conversion mechanisms comprises (a) an initial set of one or more conversion mechanisms that can be invoked in succession to convert the source data set to a final intermediate data set, and (b) a final conversion mechanism that converts the final intermediate data set to the target data set. Each conversion mechanism in the plurality of conversion mechanisms is successively invoked, in order, to convert the set of source data set to the target data set.

摘要： In accordance with one embodiment of the present invention, there is provided a technique for migrating data using a self-describing format. According to an embodiment of the technique, a first source data set, which is in a source-specific format and which conforms to a source schema, is read from a source database. Based on the structure of the first source data set, a second source data set, which conforms to the source schema but which is in a self-describing format, is generated. The second source data set is automatically converted to a first target data set, which is in the self-describing format but which conforms to a target schema. Based on the structure of the first target data set, a second target data set, which conforms to the target schema but which is in a target-specific format, is generated. The second target data set is written to a target database.
