MongoDB stores data in flexible, JSON-like documents, meaning fields can vary from document to document and data structure can be changed over time. The document model maps to the objects in your application code, making data easy to work with. MongoDB is a distributed database at its core, so high availability, horizontal scaling, and geographic distribution are built in and easy to use.
JSON is not a normal tabular data format. Unlike tabular data the structure of each piece of JSON is tailored to a specific purpose. For example a piece of JSON for a form about you and your pets would have a very different structure to a piece of JSON for a manufacturing dashboard. MongoDB expects standard tabular data. In order to visualize JSON data and find insights we need to transform it into meaningful tables.
REFORM lets you access MongoDB as tables in Tableau for visualization and analysis. Simply provide the details of the MongoDB cluster, browse even the most complex data as if it were a file browser and pick what you're interested in. Simply download the CSV from REFORM and access it with Tableau.
REFORM also supports situations where the data is too large to fit onto a single computer and situations where data needs to be analysed at scale. REFORM will stream your data directly into tables in AWS Redshift, Snowflake, AWS Athena, Google Big Query and MS SQL Server which support any size of dataset at scale and can easily be used as data sources by Tableau.
