NNDB is a C++ library that provides in-memory data storage and retrieval using syntax that is intended to feel natural for C++/STL
NSS MySQL is a NSS library for MySQL. It features full groups, passwd and shadow support.
NSS MySQL Library
provides MySQL authentication for Unix systems with NSS
a NSS library for MySQL. It features groups, passwd, shadow support
OCI is a set of C++ wrappers for Oracle Call Interface (OCI) that forms a thin abstraction layer over plain OCI calls. The code attempts to use the "Resource Acquisition Is Initialization" idiom and the "K.I.S.S." principle.
a very simple library to communicate with Oracle RDBMS through OCI written in C++
OCILIB is an open source C library to access Oracle databases. It encapsulates OCI (Oracle Call Interface), a low-level programming interface provided by Oracle that is a powerful but complex API. OCILIB is built on top of OCI, hiding its complexity and providing a simpler, more readable, and more reusable API.
odbcpp is an ODBC C++ library wrapper. The ODBC library itself is a low level C library that has many functions, all of which could return errors.
OpenDBX is an extremely lightweight but extensible C library for accessing databases with a single API. It provides a clean and simple interface across all supported databases that leads to an elegant code design automatically.
Oracle Perl Procedure Library
Oracle Perl Procedure Library is an Oracle external procedure library that allows Oracle functions and procedures to be written in Perl.
pg_collkey is a wrapper to use the collation functions of the ICU library with a PostgreSQL database server. Using this wrapper, you can specify the desired locale for sorting UTF-8 strings directly in the SQL query, rather than setting it during database installation. Default Unicode collation (DUCET) is supported. You can select whether punctuation should be a primary collation attribute or not. The level of comparison can be limited (in order to ignore accents, for example). Numeric sequences of strings can be recognized, so that 'test2' sorts before 'test10'.
a Twisted-based PostgreSQL client library which fully conforms to the DB API 2.0 specification. It's designed to run quickly and scale well. It provides connection pooling and persistence, database types, and safe conversions
a portable and tiny set of libraries for creating and reading constant databases. It manages data files that contains text or binary key/data pairs of arbitrary sizes
a simply and still small C library to read and write Paradox DB files. It supports all versions starting from 3.0. It currently has a very limited set of functions like to open a DB file, read its header and read every single record. It can also extract blob data and write it to a file
a library of routines for managing database. The database is a simple data file containing records, each is a pair of a key and a value. Every key and value is serial bytes with variable length. Both binary data and character string can be used as a key and a value
a freeware reliable database library
SpatiaLite is a library for geographic information systems (GIS) that implements the core OpenGIS specification. It provides SQLite with basic support for spatial data is intended for lightweight GIS projects.
a C++ wrapper for SQL libraries. The goal is to have a simple, uniform interface for accessing any SQL library on any platform that supports standard C++
StactiveRecord is a C++ library designed to make simple database use simple. It was inspired by Ruby on Rails' Active Record, however, no similar look, feel, or performance is guaranteed. It uses an object-relational mapping pattern to represent records as objects. It also provides persistent (basic) object relationships (one to many, many to many, one to one).
Tntdb is a c++-class-library for easy database-access. It creates a thin database independent layer, which loads drivers when needed. Currently postgresql and mysql is supported.
Tokyo Cabinet is a library of routines for managing a database. It is the successor of QDBM. Tokyo Cabinet runs very fast. For example, the time required to store 1 million records is 1.5 seconds for a hash database and 2.2 seconds for a B+ tree database.
TransactionKit is a C library that provides key/value based hash tables and was designed to fill the gap between simple, lightweight key/value type primitives, and the more advanced features available in heavyweight databases.
consists of a library and some simple utilities for creating and maintaining a shared-memory database associating users with IP addresses, or users with established TCP connections
UPPAAL DBM Library
DBMs [dill89, rokicki93, lpw:fct95, bengtsson02] are efficient data structures to represent clock constraints in timed automata [ad90]. They are used in UPPAAL [lpy97, by04, bdl04] as the core data structure to represent time. The library features all the common operations such as up (delay, or future), down (past), general updates, different extrapolation functions, etc.. on DBMs and federations. The library also supports subtractions. The API is in C and C++. The C++ part uses active clocks and hides (to some extent) memory management.
VSQLite++ is a portable SQLite wrapper library for C++.
Wave Database Interface
provides a consistent, fast, and reliable database C interface. At the moment the only database supported is Sybase/CT-Lib
a wrapper library which provides an SQL-subset interface to Xbase DBMS
a modification (i.e. bugfix and enhancement) of the xbase1.8.1 library
