Opening databases

XML and GEDCOM databases require all data to be held in memory. GRAMPS' native grdb format does not. Thus, a database with a grdb 
format can access data quicker and more efficiently.

More quickly access the disk than memory? I don't think so. But maybe this option goes away with the new Family Tree Manager anyway? --Dsblank 07:21, 10 September 2007 (EDT)

The reason this is faster is due to the fact that a database has indexes, and the other format do not. bmcage 03:52, 11 September 2007 (EDT)
I think the original comment refers to large files/databases. If you are loading a huge xml or gedcom file into memory then it can fill the whole physical memory leading to swapping. A database will scale better with large data volumes. --Gburto01 05:41, 11 September 2007 (EDT)

If a family tree contains archives (snapshots of previous version), you will be able to open them too by the same procedure.

This is not what Database_Formats#The_Future_-_GRAMPS_3.0 says. And as my current GRAMPS 3.0 won't display the Archive button, I can't try it out. Has the design changed? --Annej 07:15, 11 September 2007 (EDT)
