Patent number: 11449522Abstract: Sensor data (or IoT) analytics plays a critical role in taking business decisions for various entities (e.g., organizations, project owners, and the like). However, scaling of such analytical solutions beyond certain point requires adopting to various computing environments which seems to be challenging with the constrained resources available. Embodiments of the present disclosure provide system and method for analysing and executing sensor observational data in computing environments, wherein extract, transform, load (ETL) workflow pipeline created by users in the cloud, can be seamlessly deployed to job execution service available in cloud/edge without any changes in the code/config by end user. The configuration changes are internally handled by the system based on the selected computing environment and queries are executed either in distributed or non-distributed environments to output data frames.Type: GrantFiled: June 28, 2021Date of Patent: September 20, 2022Assignee: TATA CONSULTANCY SERVICES LIMITEDInventors: Tanushyam Chattopadhyay, Arindam Halder, Sangram Dasharath Gaikwad, Tania Ghosh, Abhisek Das, Shubhrangshu Ghosh, Suvra Dutta, Prateep Misra
