12、) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issu

13、ing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these top

14、ics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this publication, the expression “A

33、l 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 explosiv

34、e 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 Y series Supplement 40 (07/2016) 3 complex or are arriving so fast that traditional data processing method

35、s 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.

36、 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. Unstructu

37、red 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. Big data is used in many fields, where data processing is characterized by scale (volume

38、), diversity (variety), speed (velocity) and possibly others like credibility (veracity) or business value, if traditional methods and tools are not efficient. These characteristics, usually called vs, can be explained as following ITU-T Y.3600: Volume: refers to the amount of data collected, stored

39、, analyzed and visualized, which big data technologies need to resolve; Variety: refers to different data types and data formats that are processed by big data technologies; Velocity: refers to both how fast the data is collected and how fast the data is processed by big data technologies to deliver

40、 expected results. NOTE Additionally, veracity refers to the uncertainty of data, and value refers to the business results from gaining new information using big data technologies. Other vs can be considered as well. Taking into account the described above vs characteristics, big data technologies a

41、nd services can resolve many new challenges, and can also create more new opportunities than ever before ITU-T Y.3600: Heterogeneity and incompleteness: data processed using big data can miss some attributes or introduce noise into data transmission. Even after data cleaning and error correction, so

42、me incompleteness and some errors in data are likely to remain. These challenges can be managed during data analysis b-CRA. Scale: processing of large and rapidly increasing volumes of data is a challenging task. Using data processing technologies, the data scale challenge is mitigated by evolution

43、of processing and storage resources. However, nowadays data volumes are scaling faster than resources are evolving. Technologies such as parallel databases, in-memory databases, non-SQL databases and analytical algorithms resolve this challenge. Timeliness: the acquisition rate and timeliness, to ef

44、fectively find elements in a limited-time period that meet a specified criterion in a large dataset, are new challenges faced by data processing. Other new challenges are related to the types of criteria specified, and need to devise new index structures and responses to the queries having tight res

45、ponse-time limits. Privacy: data about human individuals, such as: demographic information, Internet activities, commutation patterns, social interactions, energy or water consumption, are being collected and analyzed for different purposes. Big data technologies and services are challenged to prote

46、ct personal identities and sensitive attributes of data throughout the entire data processing process, while respecting applicable data retention policies. Positive resolution of the above challenges opens new opportunities to discover new data relationships, hidden patterns or unknown dependencies

47、ITU-T Y.3600. 4 Y series Supplement 40 (07/2016) 6.2 Benefits of big data Big data technologies can provide many benefits such as data accessibility, productivity of business processes, and cost reduction to private via public sector. Big data technology increases data accessibility by: Unlocking si

48、gnificant value by making information transparent; Creating and storing transactional data in digital form; Reducing time for finding/accessing the correct data. Big data technology improves productivity by: Real-time monitoring and forecasting of events that impact either business performance or op

49、erations; Timely insights from the vast amount of data; Identifying significant information that can improve decision quality or minimize risks; Creating new service models using big data analytics. Big data technology reduces cost by: Scale-out of data storage; Identifying and reducing inefficiencies. 7 Related technical areas of big data 7.1 Cloud computing Cloud computing is a paradigm for enabling network access to a scalable a
