TAKE A SWIM IN THE DATA LAKE continue to grow exponentially .
“ Everybody says they want to do it , but there are very few actual referenceable data lake implementations anywhere ,” Gardner said . “ Although it seems like it would be the archetypal way to use it , people haven ’ t necessarily given it the governance that it needs . But the over-governance of a data warehouse was one of the problems being solved by the data lake . We went from one extreme to another of people thinking they should move away from having a tightly-governed operational principal being applied to them to having no governance applied whatsoever . People are thinking , ‘ It ’ s cheap , so I can just copy data and copy data ,’ but we ’ ll be going back to the problems
“ Having ( information ) landed in a data lake in its raw form is a great opportunity for an analyst to access it and discover if there ’ s any insight to it .”
- Alec Gardner , General Manager at Teradata ANZ we created 30 years ago and why we actually invented data warehouses .
“ It ’ s not as common as we would be led to believe . Organisations are struggling with it a bit , as they ’ ve gone through the challenge of looking at it and understanding it . It ’ s a fairly complex computer system . It ’ s relatively hard to use compared to other business intelligence and data warehouse systems . It ’ s in the minority definitely , but we ’ re seeing a great interest in it from our customer base because of the way our customers approached the problem .”
At Teradata , which is a provider of software , hardware and services to help customers get new data and use the data lake , their job is to help their clients with more sophisticated analytics , show them how to store it and find out if there ’ s value in it . They work very closely with Telco Systems and banking companies to assist them on how to use more sophisticated analytics and show them how to store it , whether it be in a data warehouse or in a data lake , in order to retain it all . The biggest challenge with this , according to Gardner , is understanding it . Although some basic aspects of it can be applied quickly
