For others, it may take tens or hundreds of terabytes before data size becomes a significant consideration." A 2016 definition states that "Big data represents the information assets characterized by such a high volume, velocity and variety to require specific technology and analytical methods for its transformation into value".
A 2018 definition states "Big data is where parallel computing tools are needed to handle data", and notes, "This represents a distinct and clearly defined change in the computer science used, via parallel programming theories, and losses of some of the guarantees and capabilities made by Codd’s relational model." The type and nature of the data.
There are a number of concepts associated with big data: originally there were 3 concepts volume, variety, velocity.
Lately, the term "big data" tends to refer to the use of predictive analytics, user behavior analytics, or certain other advanced data analytics methods that extract value from data, and seldom to a particular size of data set.

Since then, Teradata has added unstructured data types including XML, JSON, and Avro. (now Lexis Nexis Group) developed a C -based distributed file-sharing framework for data storage and query. The two platforms were merged into HPCC (or High-Performance Computing Cluster) Systems and in 2011, HPCC was open-sourced under the Apache v2.0 License.
This type of architecture inserts data into a parallel DBMS, which implements the use of Map Reduce and Hadoop frameworks.
