If you have a database sql file on your computer which you need to upload to your WordPress’ database on your hosting server, you could try uploading it through phpMyAdmin.
It’s easier doing it that way, however, if your database is upwards of 20 MB, then you may have troubles uploading it this way. The reason is that phpMyAdmin simply uploads the entire file all at once, but since the file is so big, it takes too long to upload and your web browser (Firefox, Internet Explorer, etc.) will do what we call timeout. This means it was waiting too long for a task to happen, so it just stalled.
Big Dump is a way around that. Big Dump splits up your upload into smaller sizes so your web browser doesn’t timeout. Download Big Dump here.
