COVID-19 data is voluminous describing the pandemic trend around the globe. How does Big Data help decision-makers understand the pandemic behaviour which is very crucial in responding to the situation? How do data analytics on the COVID-19 spreading pattern which is time-series in nature may provide insight into the situation that may lead to a better response through forecasting future trends? This paper aims to explain the concept of Big Data and its applications that demonstrates its potential for responding to the pandemic. COVID-19 data analytic is proposed using sliding window time-series forecasting method and demonstrated using data from 25th January until 10th October 2020 obtained from the Malaysian Ministry of Health and Department of Statistics Malaysia website. The data analytics demonstrated the value gain for useful insights.enBig Data, time-series, predictive analytics, data analyticsArticle517033S4
