SymmetricDS is Web-enabled, database independent, data synchronization/replication software. It uses Web and database technologies to replicate tables between relational databases in near real time. The software was designed to scale for a large number of databases, work across low-bandwidth connections, and withstand periods of network outage. It includes support for Oracle, MySQL, PostgreSQL, H2, HSQLDB, Derby, MS SQL Server, Firebird, IBM DB2, Informix, Interbase, and Greenplum databases.
Jigsaw is an embedded data-store designed for the development of data-warehouse, analytical, and machine learning applications. Jigsaw can perform over one million operations a second, and scale to store tera-bytes of data. The object library contains classes for representing ordered and unordered mappings, highly compressed bit vectors with a range of set theoretic operators, and directly integrates a high performance sort system.
The NCBI C++ Toolkit provides portable libraries and applications for assisting genetic science. These include libraries for networking, SQL and BerkeleyDB access, CGI and HTML handling, ASN.1 and XML handling, sequence alignment engines, sequence retrieval engines, BLAST database engines, FLTK and OpenGL graphics toolkits, and basic system utilities.
libsqljdbc_auth provides support for using Windows integrated authentication with the Microsoft SQL Server 2005 JDBC Driver under Unix operating systems. SQL Server Authentication is not secure and is difficult to manage in an environment with large numbers of database servers, but it is often the only option when connecting to an SQL Server Database from non-Windows operating systems. This library allows users of other operating systems to use the more secure Integrated Authentication method with Microsoft's SQL Server 2005 JDBC driver using native Kerberos authentication libraries.
FederatedX Pluggable Storage Engine is a storage engine for MySQL that allows you to create a table that uses a network connection to a remote database table as its data source, as opposed to most storage engines that use a table file or tablespace file as a data source. It is a fork of the MySQL Federated Storage Engine. Enhancements include being able to pass pushdown conditions (such as LIMIT and non-indexed fields in where clauses) to avoid huge data sets, improvements to transactional functionality, and support for other connection schemes (ODBC, JDBC, etc).
