Nowadays knowledge is power. In the informational era, the ability to manipulate large datasets is essential for making long term strategies. More and more companies and official statistics offices need to use large databases but also by increasing the volume of data it increases the complexity of manipulating it. A basic economy rule is that the supply follows the demand; hereby, much software for manipulating big data was created in order to follow the necessity. The aim of this paper is to underline the performance of R in manipulating large databases. Regarding to this, the paper is primarily intended for people already familiar with common databases and statistical concepts. The paper illustrates as its best how simply R - both open-source and commercial versions – is used to handle large databases manipulation.
