In Sellercloud, for the reporting suite, we use a process that is similar to the process in computing referred to as ETL (Extract, Transform, Load). This is the general procedure of copying data from one or more sources (In our case, this would be the part of the database that has all the operational data such as order details, shipping, etc.) into a destination system (the part of the database where the P&L data exists for reports) which represents the data differently from the source or in a different context than the source.
