Database Access in R

Course Features

Course Details


The Database Access in R course discusses concepts related to R programming, including dataframe manipulation, accessing common file formats, traditional Relational DataBases, and NOSQL stores like MongoDB and Cassandra. At the end of the program, participants will be equipped to leverage data from various sources that data scientists and analysts most commonly have to work with. As a result of the training, data science professionals will be able to manipulate, transform, and combine disparate data sets in order to extract useful insights. Further, as a part of the program, participants while working in a practical learning environment will be familiarized with various concepts and tools such as:

Data Frames and Data Files in R
Relational Databases
NOSQL Databases
