Business Analytics @IIT


Yday, I attended 'Analytics for Business' session by Aaum Analytics at Indian Institute of Technology Park.  Itz pretty interactive and deep technical discussions.  In spite of weekend, significant set of participants came for the session, which reflects the thirst on Big Data technology.

Few take away points:

Recommended solution
  1. Persist raw inbound data in the original file format with cheap cost, if required
  2. Process the inflow data; summarize those information; then persist in traditional DB
  3. It helps the reporting layer to extract & present the report in better way

Challenges to Adapt
  1. Return on Investment (RoI) business justification
  2. Key Performance Indicator (KPI) missing accuracy
  3. Unavailable Talent pool
  4. Customer, Analyst, Developer growing requirements gap
