Throughout his career as a BODS professional, JD has collaborated with clients using both SQL and HANA databases, some of which were multiple instance environments.  During his time working at a previous client, they were using two instances, one for use by the data migration team for loading data into S/4 and the other by the data integration team for extracting data from S/4 into data marts for running reports. JD has a strong attention to detail and understands the steps that are needed to improve ETL report efficiency.
