Overview
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 to gain actionable insights from complex organizational data through data preparation and analytics. In this blog, let us discuss about importing, analyzing, and visualizing large volume of financial or bank data in Datameer.

- Log in to Datameer using your login credentials.
- In the left pane, click Connection –> Workbook.
- Open the required workbook. A popup window with Formula Builder tab will be opened as shown below:
Setting up Data using Formulas
Formulas – Grouping Records with GROUPBY
This function is used to create groups of records based on the column selected. In the left pane of Formula Builder, select Grouping and choose GROUPBY in the relevant right pane to group the records in a column as shown below: 
The grouped records will be displayed as shown in the below diagram: 
Formulas – Counting Records with GROUPCOUNT
