What is Data Science ?
At the core is data. Troves of raw information, streaming in and stored in enterprise data warehouses. Much to learn by mining it. Advanced capabilities we can build with it. Data Science is ultimately about using this data in creative ways to generate business value:
What is Data Munging ?
Raw data can be unstructured and messy, with information coming from disparate data sources, mismatched or missing records, and a slew of other tricky issues. Data munging is a term to describe the data wrangling to bring together data into cohesive views, as well as the janitorial work of cleaning up data so that it is polished and ready for downstream usage. This requires good pattern-recognition sense and clever hacking skills to merge and transform masses of database-level information. If not properly done, dirty data can obfuscate the ‘truth’ hidden in the data set and completely mislead results. Thus, any data Scientist must be skillful and nimble at data munging in order to have accurate, usable data before applying more sophisticated analytical tactics.
