DB_Browser is a CGI tool for developers working with any relational database supported by Perl::DBI. It easily facilitates searching, editing, and adding to tables within a database. While it can be used as a regular interface to database data itself, it works well as a supplemental tool for developers creating their own primary interface.
GQL is a C++ library for generic SQL database access, modeled after JDBC (Java Database Connectivity). It includes drivers for PostgreSQL, MySQL, and SQLite, and includes GQL-Shell, an interactive database terminal called that features command-line editing, history, and database metadata (schema) browsing.
The Information System Development Kit gives the developer a platform-independent method of creating Information Systems with data forms, SQL database access, database-browsing support, report generator and many other useful features. ISDK is now in a development stage and it is available only for the Linux operating system. The form module now works on text terminals using the ncurses library (not functional right now), and on the X-Window system using the GTK+ toolkit.
iSQL(IndependentSQL)-Viewer is a JDBC 2.0-compliant application that can take advantage of platform features such as transactions, running batch modes, and database abstraction. Even in heterogeneous database environments, it supports all database platforms with a JDBC 2.0-compliant driver, such as PostgreSQL, MySQL, and Oracle. It provides a variety of tools to carry out both simple and complex database activities.
