Variety

Variety defines the nature of data that exists within big data. This includes different data formats, data semantics and data structures types.

Variety is geared toward providing different techniques for resolving and managing data variety within big data, such as:

• Indexing techniques for relating data with different and incompatible types
• Data profiling to find interrelationships and abnormalities between data sources
• Importing data into universally accepted and usable formats, such as Extensible Markup Language (XML)
• Metadata management to achieve contextual data consistency
