Datameer, an end-to-end Big Data analytics platform, is built on Apache Hadoop to perform integration, analysis, and visualization of massive volumes of both structured and unstructured data. It can be rapidly integrated with any data sources such as new and existing data sources to deliver an easy-to-use, cost-effective, and sophisticated solution for Big Data analytics. It simplifies data extraction, data transformation, data loading, and real-time data retrieval. It helps gain actionable insights from complex organizational data through data preparation and analytics. In this blog, let's discuss importing, analyzing, and visualizing large volumes of financial or bank data in Datameer.
