SpatiaLite is a spatial extension to SQLite, providing vector geodatabase functionality. It is similar to PostGIS, Oracle Spatial, and SQL Server with spatial extensions, although SQLite/SpatiaLite aren't based on client-server architecture: they adopt a simpler personal architecture. i.e. the whole SQL engine is directly embedded within the application itself: a complete database simply is an ...
GeoPackage (GPKG) is an open, non-proprietary, platform-independent and standards-based data format for geographic information systems built as a set of conventions over a SQLite database. Defined by the Open Geospatial Consortium (OGC) [ 2 ] with the backing of the US military [ 3 ] and published in 2014, GeoPackage has seen widespread support ...
A spatial database is a general-purpose database (usually a relational database) ... SpatiaLite extends Sqlite with spatial datatypes, functions, and utilities.

The file format is the native spatial data storage format for Autodesk GIS programs MapGuide and AutoCAD Map 3D. As of 2014 SDF format version SDF3 (based on SQLite3) uses a single file. Prior versions of the format required a spatial index file (SIF), with an optional key index file (KIF) to speed access to the file.
The origin of the geodatabase was in the mid-1990s during the emergence of the first spatial databases.One early approach to integrating relational databases and GIS was the use of server middleware, a third-party program that stores the spatial data in database tables in a custom format, and translates it dynamically into a logical model that can be understood by the client software.
Simple Features (officially Simple Feature Access) is a set of standards that specify a common storage and access model of geographic features made of mostly two-dimensional geometries (point, line, polygon, multi-point, multi-line, etc.) used by geographic databases and geographic information systems.
