The DBD::Mock perl module is a simple mock DBD implementation used for testing.
It's entirely self-contained so that you can extract the single library file
(DBD/Mock.pm), put it in your own distribution and be able to run DBI-based
tests even though you don't have information about a database.
DBD::PgPP is a Pure Perl client interface for the PostgreSQL database.
It implements the PostgreSQL client/server network protocol and doesn't
need an external PostgreSQL client library like "libpq" for it to work.
Consequently, it allows one to connect to a PostgreSQL server from
operating systems to which PostgreSQL has not been ported.
This module automatically inflates/deflates DateTime objects
corresponding to applicable columns. Columns may also be
defined to specify their nature, such as columns representing a
creation time (set at time of insertion) or a modification time
(set at time of every update).
DBIx::Class::Schema::Config is a subclass of DBIx::Class::Schema that
allows the loading of credentials from a file. The actual code itself
would only need to know about the name used in the configuration file.
This aims to make it simpler for operations teams to manage database
credentials.
This module provides a synchronous and asynchronous driver for Tarantool.
The driver does not have external dependencies, but includes the official
light-weight Tarantool C client (a single C header which implements all
protocol formatting) for packing requests and unpacking server responses.
This module allows use of the CQL3 interface of a Cassandra
database. It fully supports asynchronous operation via IO::Async,
allowing both direct queries and prepared statements to be managed
concurrently, if required. Alternatively, as the interface is entirely
based on Future objects, it can be operated synchronously in a
blocking fashion by simply awaiting each individual operation by
calling the get method.
Tie::LevelDB is the Perl Interface for Google NoSQL database called LevelDB. See
http://code.google.com/p/leveldb/ for more details.
Interface is implemented both as a reflection of an original LevelDB C++ API and
a Perl-ish TIEHASH mechanism.
PEAR MDB is a merge of the PEAR DB and Metabase php database abstraction layers.
It provides a common API for all support RDBMS. The main difference to most
other DB abstraction packages is that MDB goes much further to ensure
portability.
Currently supported RDBMS are MySQL, PostGreSQL, Oracle, Frontbase, Querysim,
Interbase/Firebird, and MSSQL
PEAR MDB2 is a merge of the PEAR DB and Metabase php database abstraction
layers.
It provides a common API for all supported RDBMS. The main difference to
most other DB abstraction packages is that MDB2 goes much further to
ensure portability. MDB2 provides most of its many features optionally
that can be used to construct portable SQL statements.
Percona Toolkit is a collection of advanced command-line tools used by Percona
support staff to perform a variety of MySQL and system tasks that are too
difficult or complex to perform manually, including:
Verify master and replica data consistency
Efficiently archive rows
Find duplicate indexes
Summarize MySQL servers
Analyze queries from logs and tcpdump
Collect vital system information when problems occur
