SFCGAL is a C++ wrapper library around CGAL with the aim of supporting ISO
19107:2013 and OGC Simple Features Access 1.2 for 3D operations.
SFCGAL provides standard compliant geometry types and operations, that can be
accessed from its C or C++ APIs. PostGIS uses the C API, to expose some
SFCGAL's functions in spatial databases
Xapian is an Open Source Probabilistic Information Retrieval library,
released under the GPL. It's written in C++, with bindings to allow use
from other languages.
Xapian is designed to be a highly adaptable toolkit to allow developers to
easily add advanced indexing and search facilities to their own
applications.
Xapian features include:
- Ranked probabilistic search - word importance weighting
- Relevance feedback
- Phrase and proximity searching
- Full range of structured boolean search operators
- Term stemming
- Database files > 2GB
- Platform independent data formats
- Allows simultaneous update and searching.
Slony-I is enterprise-level "master to multiple slaves"
replication system with cascading and failover.
The big picture for the development of Slony-I is to build
a master-slave system that includes all features and
capabilities needed to replicate large databases to a
reasonably limited number of slave systems.
Slony-I is developed as a system for data centers and backup
sites, where the normal mode of operation is that all nodes
are available.
Differences from 1.2 stream
- Removal of TABLE ADD KEY
- It drops all support for databases prior to PostgreSQL version 8.3.
SOCI is a database access library for C++ that makes the illusion of embedding
SQL queries in the regular C++ code, staying entirely within the Standard C++.
The idea is to provide C++ programmers a way to access SQL databases in the most
natural and intuitive way. If you find existing libraries too difficult for your
needs or just distracting, SOCI can be a good alternative.
SQLCacheD is a memory-based SQL database intended for use as a memory cache
engine. In purpose, it.s similar to (and inspired by) memcached but allows
fine-grained data manipulation using SQL.
sqliteman is the best developer's and/or admin's GUI tool for
Sqlite3 in the world. No joking here (or just a bit only). It
contains the most complete feature set of all tools available.
And much more, it's available for all major platforms, and
it's free.
SQLiteStudio is a SQLite database manager with the following features:
* Intuitive interface
* Powerful, yet light and fast
* Exporting to various formats (SQL statements, CSV, HTML, XML, PDF, JSON)
* Importing data from various formats (CSV, custom text files)
* Numerous small additions, like formatting code, history of queries executed
in editor windows, on-the-fly syntax checking, and more
* Unicode support
* Configurable colors, fonts and shortcuts
This is alternative to ancient isql - interactive
and comfortable database query tool for Sybase.
This project provides comprehensive monitoring of PostgreSQL servers using a
natively compiled Zabbix agent module, written in C.
The module enables discovery and monitoring of tablespaces, databases,
namespaces, tables, indexes, etc.
A preconfigured Zabbix Template is also included for your convenience.
LMDB is an ultra-fast, ultra-compact key-value data
store developed by Symas for the OpenLDAP Project.
It uses memory-mapped files, so it has the read
performance of a pure in-memory database while still
offering the persistence of standard disk-based
databases, and is only limited to the size of the
virtual address space, (it is not limited to the
size of physical RAM). LMDB was originally called
MDB, but was renamed to avoid confusion with other
software associated with the name MDB.
