GENERATE FIELD MAPPING

摘要

In one aspect, source fields in the data format of the source data store are transformed and mapped to a format suitable for the target data store. In the user interface of the mapping application, mapping templates using mapping functions can be defined and generated. Mapping template comprises various restriction conditions to determine compatible source fields from among the source fields in the source data store. Mapping functions in the mapping template enable such automation in determining compatible source fields and applying the mapping function to the determined compatible source fields.

主权项

1. An article of manufacture including a computer readable storage medium to store instructions, which when executed by a computer, cause the computer to:
receive an expression including a function to be applied to a plurality at source fields of a source data store; receive conditions to restrict application of the expression to compatible source fields of the plurality of source fields; generate a mapping template based on the received expression and the received conditions; receive selection of one or more source fields of the plurality of source fields; receive selection of the mapping template to be applied to the selected one or more source fields; and apply the mapping template to the compatible source fields to generate a target field.
