The YB.ORM library aims to simplify writing C++ code that has to deal with SQL databases. The goal is to provide a convenient interface like SQLAlchemy (Python) or Hibernate (Java). The library itself is cross-platform and supports a variety of SQL dialects: SQLite3, MySQL, Postgres, Oracle, and Firebird. Integration with Boost, Qt4, and wxWidgets is built-in. In a typical usage scenario, you would describe your database schema and table relationships in a simple XML-based format, generate SQL code to populate database schema with tables, generate C++ classes, add application-specific logic to the classes, and use these classes in cooperation with the Session object to query objects from the database, create new or modify/delete existing objects, or link and unlink objects using relations. Simple serialization to XML is supported along with connection pooling.
Relational Ètudes (re, for short) is an implementation of the relational model. Written in PHP, re can be considered a PHP Framework. Specifically, re tries to implement the ideas presented in the book "Databases, Types, and the Relational Model" (The Third Manifesto). As such, re is based on a rigorous scientific theory, and thus has wider applicability. For instance, from a Model-View-Controller (MVC) approach in software development, re can be considered as the "Model" component. It is even possible to implement your own MVC-type framework using re as its main foundation. re has a consistent and intuitive application programming interface (API). Relational operators are supported, thus, data/set manipulation is simplified. Applications using re will be easy to maintain and extend. Distributed data can be easily used. Business rules are cleanly implemented. It should be very easy to integrate re in your projects, since it is designed to be framework agnostic.
Collectables Database is a simple, easy-to-use application for using the control and data management capabilities of Postgres to catalog various kinds of collections. It delivers content in a format that is easy to use and manipulate within the convenience of a modern Web browser. The initial focus of the application is on cataloging a comic book collection. Collectables Database can run from a hosted Web server or on the user's local machine through the use of a virtual appliance.
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.
SafiWorkshop allows you to design, test, debug, and deploy advanced process flow applications (like IVRs) from a single, unified development environment. For database work, it includes a fully featured SQL query editor. SafiWorkshop also includes some Asterisk PBX specific features like an audio prompt editor.
lib4d_sql is a C library that provides the required functions (connect, prepare, execute, etc.) for writing an SQL client for 4D databases. It uses the public 4D SQL protocol, which is supported by 4D products since version 11. It is already used by the PDO_4D Open Source project, and it might be used to provide others drivers for JDBC, ADO, or ActiveRecord.
