- Move data, harmonizing, cleaning, resulting duplicate of data
- Huge demand on system a lot processing power to do data consolidation, can be slow
- Not useful and fragmented views of data due to duplicate copies of data
- High maintenance cost due to multiple skills needed
- Lack of innovation and agility to adapt today growth of digital world 

In summary
- Data in different application silos is causing no holistic view / partial business view
- Multiple copies of data is causing no real time insight to user
- Batch processing lead to limited ability to innovative

Above is the summarized of my study and understanding for C_HANAIMP_12 certification preparation.
