sqlite3-ruby provides an interface for the SQLite DB engine version 3. This differs from the DBD::SQLite module in that it is more complete, and from the ruby DBI version of SQLite in that it is SQLite specific, so you can do things that would otherwise be more difficult via DBI. If you want portability between backends, use DBI. If you want ease of use with SQLite, use this.

The StateMachines ActiveModel integration is useful for both standalone usage and for providing the base implementation for ORMs which implement the ActiveModel API. This integration adds support for validation errors and dirty attribute tracking.

The StateMachines Active Record 4.1+ integration adds support for database transactions, automatically saving the record, named scopes, validation errors.

spatialite-tools is a collection of open source Command Line Interface (CLI) tools supporting SpatiaLite. * spatialite: a complete CLI front-end, more or less equivalent to the well known sqlite3 front-end, but fully supporting SpatiaLite * spatialite_tool: a tool supporting import/export of Shapefiles and DBF-files * shp_doctor: a diagnostic tool to check anomalous shapefiles * exif_loader: an import tool for EXIF or EXIF-GPS (JPEG) pictures * spatialite_network: a tool creating a VirtualNetwork (supporting shortest path / routing SQL queries) * spatialite_gml: a tool importing GML files * spatialite_convert: a tool converting DB-files from different versions of SpatiaLite * spatialite_dxf: an tool importing DXF files * OSM-tools: spatialite_osm_raw, spatialite_osm_filter, spatialite_osm_map, spatialite_osm_net, spatialite_osm_overpass: tools supporting OpenStreetMap datasets * XML-tools: spatialite_xml_load, spatialite_xml_collapse, spatialite_xml_print, spatialite_xml_validator: tools supporting XML files processing

SpatiaLite is just a small sized SQLite extension. Once you have installed SpatiaLite (a very simple and elementary task), the SQLite DBMS is enable to load, store and manipulate Spatial Data (aka GeographicData, GIS Data, Cartographic Data, GeoSpatial Data, Geometry Data and alike). SpatiaLite implements spatial extensions following the specification of the Open Geospatial Consortium (OGC).
