Gramps SQL Database
This page documents the format of a SQL database version of the GRAMPS BSDDB datastore. This can be seen as a step towards a SQL backend for GRAMPS, and for supplying data to other applications, such as a GRAMPS Webapp.
GRAMPS SQL database Overview
The current version of this project outputs the GRAMPS BSDDB data into a relational SQLite database. You can access this functionality through the ExportSql and ImportSql programs of the Third-party Plugins.
After dropping the above plugins into your .gramps/plugins subdirectory, you can:
python src/gramps.py -O "My Family Tree" -e familytree.sql
This will export the entire contents of your database (not including bookmarks, gramplets, nor any meta data, etc.) into a sqlite3 database named "familytree.sql'. Likewise, you can read the data it a new database:
python src/gramps.py -i familytree.sql
NOTE: if you import this file into an existing family tree, you will get corrupted data for any items that overlap with internal numbering! This has the same effect as importing with GRAMPS XML.
Exporting a SQL database can take up to 2 seconds per record to output. Importing a SQL database can take up to 1 second a record to read in.
After exporting, you can then access your data using any program that can read sqlite files. For example, on Linux:
