What does Data Science Constitute?
Before we dive into the data science career opportunities, we shall briefly discuss what data science contains to appreciate each role well. Data science brings together 4 different fields – computer science, probability, statistics, and business/domain knowledge. All these require business intelligence and knowledge of big data. Big data is a collection of humongous data sets that are so complex that relational database systems (RDBMS) are not able to handle them. To use this chunk of data, we need to perform data science on the dataset or its sample. Data can be generated in many forms – raw or unstructured, structured, natural (human) language data, machine-generated data, audio, video, image, graph-based data, and streaming (real-time) data. Analyzing all these types of data requires the following steps:
- Setting the business/research goal
- Data collection
- Preparing data
- Data exploration
- Data modeling
- Visualization and automation
