Top Ten Open-Source Big Data Database

Data has become a powerful tool for the global workforce. It’s a prerequisite to translate massive amounts of unstructured and structured information into meaningful and valuable business insights for future growth. Hence, the current global market is flooded with a wide range of big data tools to process and store information. Data is meaningless until it is turned into a piece of useful information and knowledge that can aid in the management of an enterprise. The innovation around big data offers a pool of endless functionalities that deals with insight and forecasting to save, efficiency, and minimize cost for an organization. According to a study conducted by International Data Corporation, it is estimated that the global data creation will surpass 163 Zettabytes by the year 2025. This will be a tenfold amount of data that is generated by 2017. Many business enterprises across the globe heavily rely on open-source database solutions to manage their data. Many organizations primarily refer to opt for free tools due to their versatility and the chance to contribute to the platform’s evolution. The world is changing faster, and there is a need for an organization to invest heavily in data analytics.
