Definition :
Big data is an extremely large data set that may be analyzed computationally to reveal patterns, trends, and associations, especially relating to human behaviour and interactions.
Big data is a term for data sets that are so large or complex that traditional data processing applications are inadequate.
Big data is a collection of data sets so large and complex that it becomes difficult to process using on-hand database management tools or traditional data processing applications.
characteristics:
Volume:
The quantity of generated and stored data.
Velocity:
The speed at which the data is generated and processed to meet the demands and challenges that lie in the path of growth and development.
Variety:
The type and nature of the data.
Variability:
Inconsistency of the data set can hamper processes to handle and manage it.
Veracity:
The quality of captured data can vary greatly, affecting accurate analysis.
Visualization:
The process of interpreting data in visual terms or of putting into visible form.
Value:
Transforming data into the regard that something is held to deserve, the importance, worth, or usefulness of something.
Validity :
data quality, governance, master data management (MDM) on massive, diverse, distributed, heterogeneous, “unclean” data collections.
Venue:
distributed, heterogeneous data from multiple platforms, from different owners’ systems, with different access and formatting requirements, private vs. public cloud.
Vocabulary :
schema, data models, semantics, ontologies, taxonomies, and other content- and context-based metadata that describe the data’s structure, syntax, content, and provenance.
Vagueness:
confusion over the meaning of big data
