RecDB is a recommendation engine built entirely inside PostgreSQL 9.2. It allows application developers to build recommendation applications using a wide variety of built-in recommendation algorithms such as user-user collaborative filtering, item-item collaborative filtering, and singular value decomposition. Applications powered by RecDB can produce online and flexible personalized recommendations to end-users. It is easily used and configured and allows novice developers to define a variety of recommenders that fits their application's needs in few lines of SQL. It can seamlessly integrate recommendation functionality with traditional database operations.
DBeaver is a universal database manager and SQL Client. It supports MySQL, PostgreSQL, Oracle, DB2, MSSQL, Sybase, Mimer, HSQLDB, SQLite, Derby, and any database that has a JDBC driver. It is a GUI program that allows you to view the structure of a database, execute SQL queries and scripts, browse and export table data, handle BLOB/CLOB values, modify database meta objects, etc. It has a native UI (provided by the Eclipse SWT library), great performance, and relatively low memory consumption.
InfiniSQL is a distributed in-memory NewSQL relational database management system (RDBMS). It excels at performing complex transactions which involve records on multiple server nodes. It is engineered around the actor model of concurrent programming, which enables unique scalability capabilities.
Affiliates is an affiliate management system for clubs, communities, schools, and associations. It allows you to set up and maintain a database and provides a graphical interface, a mailing and label printing tool, an email tool, an archive and initialization tool, import and export to CSV files, membership and record cards, support for JPEG images, templates for forms and documents, and networking support.
ODB is a compiler-based object-relational mapping (ORM) system for C++. It allows you to persist C++ objects to a relational database without having to deal with tables, columns, or SQL and without manually writing any mapping code. The C++ code that performs the conversion between persistent classes and their database representation is automatically generated by the ODB compiler. The ODB compiler is a real C++ compiler except that instead of producing assembly or machine code, it generates portable C++, which can in turn be compiled by any C++ compiler. ODB is not a framework. It does not dictate how you should write your application. Rather, it is designed to fit into your style and architecture by only handling C++ object persistence and not interfering with any other functionality.
Ora2Pg is a Perl module to export an Oracle database schema to a PostgreSQL compatible schema. It connects your Oracle database, extracts its structure, and generates an SQL script that you can load into your PostgreSQL database. It dumps the database schema (tables, views, sequences, indexes, grants) with primary, unique, and foreign keys into PostgreSQL syntax without editing the SQL code generated. It also dump Oracle data into PostgreSQL DB as online process or into a file. You can choose what columns can be exported for each table.
StelsCSV is a JDBC driver that allows performing SQL statements and other JDBC operations upon text files (comma separated, tab-separated, fixed length, etc.). Using this driver, users can easily create a simple database consisting of plain text files. The driver can be used for writing data importing programs and migration tools. It supports most keywords of ANSI SQL92, table joins, INSERT, UPDATE, and DELETE statements, data types, aggregate, converting, string, and user-defined SQL functions.
