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.
Groonga is a fast and accurate full text search engine based on an inverted index. Newly registered document instantly appears in search results, and updates are allowed without read locks. These characteristics result in superior performance for real-time applications. It is also a column-oriented database management system (DBMS). Compared with well-known row-oriented systems, such as MySQL and PostgreSQL, column-oriented systems are more suited for aggregate queries.
PixSteward downloads pictures and metadata from your Flickr accounts and archives them in a relational database on your computer, allowing offline searches and image exporting. With PixSteward, you can safely back up multiple Flickr photostreams with metadata to your Mac, perform sophisticated searches (even where there's no Internet connection), rapidly browse your picture archive and export original-sized JPEGs, PNGs, and GIFs (groups and one-by-one), export sets of pictures along with their metadata for use in other apps, and edit your Flickr tags, titles, and descriptions simultaneously on Flickr and within PixSteward.
Bibfilex is software to create and manage archives of bibliographical items (books, articles, etc.) according to Biblatex structure and rules. It is far less advanced than other bibliographic managers like JabRef, and allows only a few customizations. Its strength is speed and lightness, especially when used with many items. It uses SQLite as a database. It can store the items according to each of the entry types described in the Biblatex manual (book, article, etc.), import the content of a file in Biblatex format (like a JabRef database, a Mendeley BibTex exported file, or a Google Books BibTex downloaded file), export data to a Biblatex file (like a JabRef database), locate an item just typing its author name, title, etc. filter the items by selecting a keyword in a list, filter the items according to three different conditions (or to manually modify the SQL statement of the filter to make it more suitable or complex) or according to the \cite commands contained within a Latex document, associate various attachments (files of every kind) with each item, activate autocompletion of data in each field with “Ctrl + Space”, automatically create unique BibTex keys according to a pattern defined by the user, and specify the fields (columns) shown in the grid view of the data. It is also possible to replace the \cite and \printbibliography commands in a Latex document with extended citations and bibliography, which are composed according to a user-defined pattern, to export the Latex file in other formats more easily.
MUSCLE (Multi User Server Client Linking Environment) is an N-way messaging server and networking API. It includes client-side networking APIs for various languages, including C, C++, C#, Delphi, Java, and Python. MUSCLE lets programs communicate over a network via streams of serialized Message objects. The included server program ("muscled") lets its clients message each other and store information in its server-side hierarchical database. The database supports flexible queries via hierarchical wildcarding, and "live" updates via a subscription mechanism.
hamsterdb Embedded Storage is an embedded database engine written in ANSI-C. It includes B+Trees with variable length keys and records. It supports in-memory databases and endian-independent files, database cursors, multiple databases in one file, "record number" databases, and duplicate keys. hamsterdb is very fast and highly configurable. It compiles and runs on Unix platforms, Linux, Microsoft Windows, and Windows CE.
Qore PostgreSQL Module is a DBI driver module for the Qore programming language to communicate with PostgreSQL databases. The PostgreSQL driver transparently handles client and server character encodings, supports multi-threading, transaction management, stored procedure execution, and more.
