Cybercluster is a multi-master replication solution. Cybercluster has no single point of failure, an integrated load balancer, an integrated replication server, a monitoring server (to track replication), a consistency checker, an optional 2 Phase Commit for cluster-wide writing, support for all PostgreSQL features. Cybercluster is easy to setup. In contrast to many other solutions, Cybercluster is built on top of the PostgreSQL core and has full access to PostgreSQL internals. Cybercluster is heavily based on the concepts of PGCluster.
DB2 is a database management system that offers industry leading performance, scalability, and reliability on your choice of platform from Linux to z/OS. Its Web Control Center offers administrators an easy-to-use interface for maintaining databases, and can be run from any Java-enabled Web browser. For Java developers, DB2 UDB for Linux offers support for JDBC and SQLJ, and Net.Data allows for the creation of dynamic data diven Web applications. DB2 UDB for Linux allows you to harness the power of user-defined types and functions and support for Binary Large Objects.
DBHawk is a Web-based Oracle tool that provides convenient database administration and development from home, office, or remote locations. It allows developers and DBAs to do various database tasks such as browse database objects, create new objects, view dependencies between various objects, generate DDL, execute SQL queries, run Explain Plan, and export results into HTML, CSV, or PDF format. It features storage management, security management, and the ability to monitor sessions, view/modify database parameters, browse v$views, etc. It is easy to install and straightforward to use on Windows, Linux, and Unix platforms.
com.webprofusion.util.db.DBConnection is a simple wrapper Java object for JDBC database connections which is meant to help in building cross-DB SQL statements. It currently supports MySQL & MS SQL Server. It also includes the classes com.webprofusion.utils.StringUtils and com.webprofusion.SiteProperties. The dbconnection object currently uses thess classes to load settings for the DB Connection at runtime. This lets you define a properties file which specifies the dbengine and connection info.
DBMaker provides you with a professional database system with multimedia capabilities, a native ODBC interface, large database features, and cross-platform support. The unique open architecture and native ODBC interface give you the freedom to build custom applications using a wide variety of programming tools such as Visual Basic or Delphi, or query your database using existing ODBC-compliant applications.
DBPrism is an open source framework to generate dynamic XML from a database. It connects Oracle databases with Apache Cocoon, providing a high performance DBGenerator with functionality such as parallel content aggregation and ESI cache protocol. It also includes a powerlful database oriented CMS built on top of Apache Cocoon2 and DBPrism.
Daffodil DB is a SQL-99 specification compliant, lightweight, Java-based relational database engine (RDBMS). It supports almost all constructs of SQL 99 (including triggers, views, constraints, UDT, stored procedures, etc.), supports distributed transactions (XA), provides a complete JDBC 3.0 driver (including support for optional features like save points, rowsets, UDT, XA, connection pooling, etc.), and can run in embedded or server mode. It can be included as a jar file in any Java application. Daffodil DB includes Daffodil DB Browser, a GUI-based database management tool that can be used to carry out all database operations such as creating a database, creating database objects, executing SQL statements, and manipulating data, browser database objects, etc.
Data stream processing toolkit (dspt) is intended for processing huge amounts (gigabytes) of data in an efficient manner. The structure of the data files is user-defined, and the queries are written in a declarative style. Currently included algorithms range from simple filtering on predicates to aggregation and sorting. It also includes some convenience classes (e.g. for accessing BerkeleyDB databases). The toolkit does not offer as wide a range of operations as an RDBMS, but some measurements of simpler queries have shown it to be more than 10x faster than PostgreSQL.
