I'm somewhat new to the field of bioinformatics, thus I needed to know, within the scope of my master's project, which database type gnomAD truly uses. I did a great amount of research, but I still don't really comprehend it. I am aware that the gnomad data is accessible via Google Cloud and can be explored using either Hail or BigQuery.
Note: To give some context, I have my own data, so I would like to try to create my own type of exome aggregation database, and the idea was to try to replicate gnomAD and take advantage of its open code source, eventually being able to load my data into it.
But I'm attempting to understand some details first.
