Cassandra is a database product used for storing very large amounts of data. It stores the data in a similar way to an Excel spreadsheet, as a series of rows and columns. For this reason, it is often referred to as a type of "Column Store".
It differs from SQL Databases in that it doesn't allow the programmer to perform some of the more complicated types of queries that you can with SQL. This trade-off allows it to perform better when handling very large amounts of data.
