postgresql-relay can be used to as a single point of origin for all
your databases. Instead of having to remember (or modify in case
of changes) all the names of your databases, on which machines and
on which ports they are running, you only need to remember one
machine and the name of the database. The postgresql-relay will
then forward the connection to the proper database on the proper
port of the proper server. No more changes in the hundreds of clients
and scripts!
iODBC (intrinsic Open Database Connectivity) is an ODBC driver manager that
is compatible with the ODBC 2.x and 3.x specifications. It performs the
standard tasks of a driver manager, i.e. driver loading, parameter and
function sequence checking, driver function invocation, etc.
Applications linked with the iODBC driver manager will be able - through ODBC
function calls - to access simultaneously different types of data sources
within one process through suitable ODBC drivers.
iODBC is freely redistributable under either the GNU Library General Public
Licence (LGPL) or the BSD licence.
Riak is an open source, distributed database. Riak is architected for:
* Low-Latency
Riak is designed to store data and serve requests predictably and quickly, even
during peak times.
* Availability
Riak replicates and retrieves data intelligently, making it available for read
and write operations even in failure conditions.
* Fault-Tolerance
Riak is fault-tolerant so you can lose access to nodes due to network partition
or hardware failure and never lose data.
* Operational Simplicity
Riak allows you to add machines to the cluster easily, without a large
operational burden.
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.
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.
TOra is an open-source multi-platform database management GUI that
supports accessing most of the common database platforms in use,
including Oracle, MySQL, and Postgres, as well as limited support
for any target that can be accessed through Qt's ODBC support.
In addition to regular query and data browsing functionality, it
includes several additional tools useful for database administrators
and developers - which aims to help the DBA or developer of database
application. Features PL/SQL debugger, SQL worksheet with syntax
highlighting, DB browser and a comprehensive set of DBA tools.

spatial index, and realtime geofence. It supports a variety of object types
including lat/lon points, bounding boxes, XYZ tiles, Geohashes, and GeoJSON.
Features:
Spatial index with search methods such as NEARBY, WITHIN, and INTERSECTS.
Realtime geofencing through persistent sockets or webhooks.
Object types of lat/lon, bbox, Geohash, GeoJSON, QuadKey, and XYZ tile.
Support for lots of Clients Libraries written in many different languages.
Variety of client protocols, including http (curl), websockets, telnet,
and the Redis RESP.
Server responses are RESP or JSON.
Full command line interface.
Leader / follower replication.
In-memory database that persists on disk.
KchmViewer is a chm (MS HTML help file format) viewer. Unlike most existing
CHM viewers for Unix, it uses Trolltech's Qt widget library, and does not
depend on KDE or Gnome. However, it may be compiled with full KDE support,
including KDE widgets and KIO/KHTML.
The main advantage of KchmViewer is non-english language support. Unlike
others, KchmViewer in most cases correctly detects help file encoding,
correctly shows tables of context of russian, korean, chinese and japanese
help files, and correctly searches in non-english help files.
