to become a data scientist?
A data scientist takes analytics and data warehousing programs to the next level: What is the data really telling a company, and is the company able to decipher relevant data from irrelevant data? A data scientist will hopefully be able to leverage the enterprise data warehouse currently in place to take a deeper dive into the data coming out of the EDW or to analyze new types of data stored in Hadoop clusters and other big data systems. And a data scientist will not just report on data as a classic BI developer does, but also make business insights based on the data.
A data scientist is also more likely to have strong business sense and the ability to communicate data-driven conclusions to business stakeholders. Strong data scientists will not just address business problems; they'll also pick the right problems that have the most value to the organization. I feel a data scientist job is a more strategic position within an organization.
Data scientists will look through all available data with the goal of discovering a previously hidden insight, which in turn can provide a competitive advantage or address a pressing business problem. Data scientists do not simply collect and report on data -- they also look at it from many angles, determine what it means, then recommend ways to apply the data.
For a data scientist job, the best education is your typical computer science, math and/or statistics curriculum. I have heard a number of universities are creating degree programs specifically for data scientists. That could be a helpful step in boosting the available ranks of job candidates with data scientist skills.
