6 Landscape of big data from an ITU-T perspective

6.1 Characteristics and general concepts of big data
[ITU-T Y.3600] describes the characteristics and general concepts of the big data ecosystem.

With the rapid development of information and communications technology (ICT), Internet technologies and
services, huge amount of data are generated, transmitted and stored with explosive growth. Data are
generated by many sources and not only sensors, cameras, network devices, web pages, email systems, social
networks and many other sources. Datasets are becoming so large and complex or are arriving so fast that
traditional data processing methods and tools are inadequate. Efficient analytics of data within tolerable
elapsed times becomes very challenging. The paradigm being developed to resolve the above issues are
called big data [ITU-T Y.3600].
Within big data ecosystem, data types include structured, semi-structured and unstructured data. Structured
data are often stored in databases which may be organized in different models, such as relational model,
document model, key-value model, graph model etc. Semi-structured data does not conform to the formal
structure of data models, but contain tags or markers to identify data. Unstructured data do not have a pre-
defined data model and are not organized in any defined manner. Within all data types data can exist in
formats, such as text, spreadsheet, video, audio, image, map, etc. [ITU-T Y.3600].
