The document discusses the Extract, Transform, and Load (ETL) process in BXBwebsuite. It describes defining a data source connection by specifying properties depending on the type (e.g. MySQL, Oracle). Cube configurations can then be created by specifying a name and permissions. A SQL script defines which fields to transfer from the data source to the cube. Metadata can transform numeric fields into dimensions and decompose date fields. Data is loaded onto cubes which can be automated through a load frequency configuration.
