Enterprises normally have many systems where data is siloed across heterogeneous platforms with different technologies.
Carrying out data management activities means long months and multiple years of deep technical analysis of each source. In addition, this requires huge effort of developing many batch data integration jobs from data sources to consolidated data mart or a data warehouse for having aggregated and analytical reporting.
From IT perspective, employing various technical skill sets in a short time to achieve all data integration requirements is not always available.
On the other hand, business users rely heavily on having integrated data available on-demand with high level of speed. Delay of data preparation implies delays at decision making and missing potential market opportunity or being noncompliance to regulations.
