Disclaimer:
Some people call me a data scientist,
But I don't consider myself one (yet)
(( its a personal integrity thing – Machine Learning & Stats is not (yet) my strong point ))
But I do work a lot with data: designing application, infrastructure,
algorithms, processes and pipelines for big data workload – from data
acquisition to visualization

Getting Started
Some tips for beginners

14.
Bulk of your data
related work would
be in cleaning data
- Excel to JSON/CSV
- PDF to JSON/CSV
- Unstructured to structured
- Joining multiple data sources into one, where
joining key is not obvious
- Normalizing duplicates, errors, typos, language, etc
- Dealing with inconsistent schema of historical data
- Extracting more features of data points
- Enriching data with more useful information (eg: long,lat)
- Dealing with data that was poorly collected
- Dealing with aggregated data that is not quite useful
- Real-life data is a mess: SNAFU ;-)

15.
Analytic Tools & Platform
Plenty Open Source Tools available
- Simple data and analysis can be done without the need of complex Big Data
ecosystem. A ${YourFavouriteLanguage} executable is usually more than
enough to transform, clean, explore data to get initial insights and understanding
- I speak mostly in snake language, so naturally I prefer Python stuff ;-)
– Python is a strong language in scientific computing due to its history in mathematics, its
rich open source library ecosystem, and its simplicity for rapid experimentation
– Pandas, numpy, scipy, pymapreduce, xlrd, pyexcel, scikit, luigi, vaderSentiment, etc
- D3.js is highly recommended for development of data driven visualizations for
web
– Plenty of other javascript libraries to help render beautiful diagrams

16.
My Personal
Favourites :
IPython Notebook & Python libraries
Apache Zeppelin, PySpark
& Python libs
"Small" data
"Big data"
Hortonworks HDP Sandbox
(Pig, Hive, Spark, and friends)
Amazon EMR
(large cluster to crunch your data)

Goodluck!!
And most importantly,
Have Fun!!
