Simple Access API
As of version 3.0, a database API directed to plugin writers is available, The Simple Access API, accompanied with a Simple Document API for easy presentation of the data.
The normal database routines are optimized for low memory usage, and if used properly, will take up almost no memory. This is key when using large databases. Typically, instead of maintaining dictionaries or lists of objects, we can use the database "handles", and access the data only when explicitly needed. This memory efficiency comes at the cost of being fairly complicated to use.
The simplified API hides most of the complexity. Full objects are returned, so you can easily consume a lot of memory with large databases. The routines themselves do not consume a significant amount of memory, but if you decided to keep your own lists or dictionaries of data, you will consume memory quickly.
This class is specifically constructed for use in the plugins, or to make quick reports (available in the context menu's).

You can view the API in _SimpleAccess.py right here.
from Simple import SimpleAccess sdb = SimpleAccess(database) # grab our current id, so we can filter the active person out # of the data person = database.active_person() gid = sdb.gid(database.active_person()) # loop through each family in which the person is a child for family in sdb.child_in(person): # loop through each child in the family for child in sdb.children(family): #print something to terminal print sdb.name(child),sdb.gender(child), sdb.birth_date(child))
