New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 3) which is identical with ISO/IEC 20547-3 : 2020 ‘Information technology - Big data reference architecture - Part 3: Reference architecture’ issued by International Organization for Standardization (ISO) and International Electro technical Commission (IEC) was adopted by the Bureau of Indian Standards on recommendation of the Artificial Intelligence Sectional Committee, and approval of the Electronics and Information Technology Division Council.

The text of ISO/IEC Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
