The concept of ETL is not hard to understand. The notion is to create a permanent storage space for the data needed to support reporting, analysis, and other BI functions. On the surface, it may seem wasteful to store data in more than one place. The advantages, however more than justify the effort and cost of doing so. EIQ2 builds a carefully designed model that transforms sourced data from a high-speed data entry to one that supports high-speed retrieval.
