PGObject::Simple::Role provides an interface to the PGObject service locator for Moo and Moose Perl classes. This service locator is intended to integrate Perl objects with PostgreSQL user-defined functions, and this uses the "simple" mapping approach. Between PGObject::Simple::Rrole and PGObject::Util::DBMethod, it is possible to write fully-declarative classes in which all calculation logic is handed off to database functions.
DBeaver is a universal database manager and SQL Client. It supports MySQL, PostgreSQL, Oracle, DB2, MSSQL, Sybase, Mimer, HSQLDB, SQLite, Derby, and any database that has a JDBC driver. It is a GUI program that allows you to view the structure of a database, execute SQL queries and scripts, browse and export table data, handle BLOB/CLOB values, modify database meta objects, etc. It has a native UI (provided by the Eclipse SWT library), great performance, and relatively low memory consumption.
Barman (backup and recovery manager) for PostgreSQL is an administration tool for disaster recovery of PostgreSQL servers. It allows remote backups of multiple servers in business-critical environments and helps DBAs during the recovery phase. Barman's most-wanted features include backup catalogs, retention policies, remote recovery, archiving, and compression of WAL files and backups.
TinyButStrong is a template class for PHP that allows you to generate XML/HTML pages and any other files based on text source. The engine gives facilities to work with any databases, including in native PDO, MySQL, PostgreSQL, SQLite, PHP arrays, and more. It is possible to design templates using any visual editor (like Dreamweaver or FrontPage), and thus to make templates that are compatible with W3C standards for example. It features simple block management, useful display formats, conditional displaying for blocks and locators, remote XML/HTML attribute modification, a cache system, and the ability to include sub-templates and execute associated scripts. Plug-ins are supported since version 3.0.
Pyrseas provides a framework and utilities to upgrade and maintain a relational database. It currently includes the dbtoyaml utility to create a YAML description of a PostgreSQL database's tables, and the yamltodb utility to generate SQL statements to modify a database to match an input YAML specification. It also aims to develop data administration tools to supplement an agile database development process.
RecDB is a recommendation engine built entirely inside PostgreSQL 9.2. It allows application developers to build recommendation applications using a wide variety of built-in recommendation algorithms such as user-user collaborative filtering, item-item collaborative filtering, and singular value decomposition. Applications powered by RecDB can produce online and flexible personalized recommendations to end-users. It is easily used and configured and allows novice developers to define a variety of recommenders that fits their application's needs in few lines of SQL. It can seamlessly integrate recommendation functionality with traditional database operations.
The YB.ORM library aims to simplify writing C++ code that has to deal with SQL databases. The goal is to provide a convenient interface like SQLAlchemy (Python) or Hibernate (Java). The library itself is cross-platform and supports a variety of SQL dialects: SQLite3, MySQL, Postgres, Oracle, and Firebird. Integration with Boost, Qt4, and wxWidgets is built-in. In a typical usage scenario, you would describe your database schema and table relationships in a simple XML-based format, generate SQL code to populate database schema with tables, generate C++ classes, add application-specific logic to the classes, and use these classes in cooperation with the Session object to query objects from the database, create new or modify/delete existing objects, or link and unlink objects using relations. Simple serialization to XML is supported along with connection pooling.
