In view of the need to handle increasingly larger amounts of data and to better cope with the ensuing big data V-characteristics (Volume, Velocity, Variety, Veracity etc.), several large organisations have begun migrating their standard legacy Enterprise Data Warehouse (EDW) systems to Big-Data-Driven-Enterprise (BDDE) schemes, which subsume the EDW.
Many of these schemes utilise the Hadoop ecosystem supported by a variety of additional data mining and business analytics sub-systems. In this Assignment, you will look at how big organisations migrate from standard EDW to BDDE schemes (that incorporate the EDW) and will investigate the key issues that often have to be dealt with in such migrations.

(200 words)Select a suitable platform for general big data management (e.g. in-house or cloud based infrastructure) and Big Data Management System (BDMS) platform with vendor (e.g. Hadoop supplied by Cloudera CDH, AWS EMR or HortonWorks).
