akonadi-backend-sqlite - 4:22.12.3-1+b2 main

Akonadi is an extensible cross-desktop Personal Information Management (PIM)
storage service. It provides a common framework for applications to store and
access mail, calendars, addressbooks, and other PIM data.
.
This package installs everything what's needed for Akonadi to work with SQLite
as underlying data storage engine. Since SQLite is an embedded database
engine, a separate SQL server daemon is not necessary.
.
In addition, the package contains an improved QSql driver for SQLite named
"QSQLite3". It can be used by any application that needs to access SQLite
databases via standard Qt QSql framework.
