A computer-implemented method of importing data from a data source to a target storage system is disclosed. The method involves executing an automated data import process to retrieve data from the data source and update the target storage system based on the retrieved data. The automated data import process operates in dependence on a source data schema of the data source. The method involves detecting a change in the source data schema and in response to detecting the change in the source data schema modifying the automated data import process. The modified automated data import process can subsequently be used to retrieve further data from the data source and update the target storage system based on the further retrieved data.
