SQLite is a light single file SQL database that provides an excellent
platform for embedded storage of structured data.
However, while it is superficially similar to a regular server-side SQL
database, SQLite has some significant attributes that make using it like a
traditional database difficult.
For example, SQLite is extremely fast to connect to compared to server
databases (1000 connections per second is not unknown) and is particularly
bad at concurrency, as it can only lock transactions at a database-wide
level.
This role as a superfast internal data store can clash with the roles and
designs of traditional object-relational modules like Class::DBI or
DBIx::Class.
What this situation would seem to need is an object-relation system that
is designed specifically for SQLite and is aligned with its
idiosyncracies.
ORLite is an object-relation system specifically tailored for SQLite that
follows many of the same principles as the ::Tiny series of modules and
has a design and feature set that aligns directly to the capabilities of
SQLite.
