Cassandra commercial licence requirements for support, development and usage

The requirement is for the purchase of licenses required to both develop and support the existing Cassandra Hazard Log Management tool. The underlying technology architecture of Cassandra requires additional commercial software to provide essential functionality, including the look and feel of the user interface, its ability to create documents in Adobe PDF and Microsoft Office format and support the underlying data structures. The three components requiring licences are Telerik, Aspose and Ext. NET.
