GFF2 is deprecated and if possible you are strongly encouraged to use GFF3.

GFF2 databases - older and unable to represent genes with alternative splicing patterns, features with more than one level of nesting, and several other common situations.

GFF3 databases - slightly faster than GFF2 and able to represent multilevel features.

There are 3 widely used GBrowse Adaptors that use databases: Often the first step after installing GBrowse is to get the genomic data you want to see into a database that GBrowse can read. If you have a significant amount of data (and most people do) then you want to store your GBrowse data in a database and use a database adaptor. Several of those adaptors read data from database management systems ( a.k.a. GBrowse uses adaptors to read genomic data.
