    (description
     "Firebird is an SQL @acronym{RDBMS, relational database management system}
with rich support for ANSI SQL (e.g., @code{INSERT...RETURNING}) including
@acronym{UDFs, user-defined functions} and PSQL stored procedures, cursors, and
triggers.  Transactions provide full ACID-compliant referential integrity.

The database requires very little manual maintenance once set up, making it
ideal for small business or embedded use.

When installed as a traditional local or remote (network) database server,
Firebird can grow to terabyte scale with proper tuning---although PostgreSQL
may be a better choice for such very large environments.

Firebird can also be embedded into stand-alone applications that don't want or
need a full client & server.  Used in this manner, it offers richer SQL support
than SQLite as well as the option to seamlessly migrate to a client/server
database later.")

underlying operating system for caching and locking, keeping the code small and

The use of ‘zero-copy’ memory-mapped files combines the persistence of classic
disk-based databases with high read performance that scales linearly over
multiple cores.  The size of each database is limited only by the size of the
virtual address space — not physical RAM.")

Run in-memory SQL queries, including joins, directly against data in
CSV, TSV or JSON files and view the results.
@item
Configure SQLite full-text search against your database tables and run
search queries against them, ordered by relevance.
@item
Run transformations against your tables to make schema changes that
SQLite ALTER TABLE does not directly support, such as changing the type
of a column.
@item
Extract columns into separate tables to better normalize your existing
data.

Like shelve, a PickleShareDB object acts like a normal dictionary.  Unlike
shelve, many processes can access the database simultaneously.  Changing a
value in database is immediately visible to other processes accessing the same
database.  Concurrency is possible because the values are stored in separate
files.  Hence the “database” is a directory where all files are governed by
PickleShare.")
