This paper presents a conceptual model for integrating and processing medical data in three layers, comprising a total of six phases: a model for integrating, filtering, sorting and aggregating Covid-19 data. A medical data integration workflow was designed, including steps of data integration, filtering and sorting. The workflow for Covid-19 medical data from clinical records of 20400 potential patients was employed.7182022718202210210611https://wseas.com/journals/msa/2022/a225109-978.pdf10.37394/232023.2022.2.11https://wseas.com/journals/msa/2022/a225109-978.pdf10.1016/j.ins.2014.01.015Chen P., Zhang C, Data-intensive applications, challenges, techniques and technologies: A survey on Big Data, Journal of Information Sciences, 275:314–347, DOI: 10.1016/j.ins.2014.01.015. 10.1177/2050312120934839Mallappallil M, Sabu J, Gruessner A, Salifu M.
