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.
xplain2sql converts files from Xplain to SQL. It supports a very large subset of Xplain, and it can convert from Xplain to Microsoft SQL Server, DB/2, Inprise InterBase, PostgreSQL, Oracle, MySQL 5, SQLite 3 or ANSI-92 SQL. It can also generate an XML description of the generated SQL. This XML description can be used to create low-level middle-tier code. Example stylesheets for Eiffel/ECLI and Delphi/ADO are included. The C source code release should compile on any platform with an ANSI C compiler. There are binary releases for FreeBSD, Linux, Solaris x86, and Windows 2000.
SPOPS (Simple Perl Object Persistence w/ Security) is a robust and powerful Perl module that allows you to serialize objects. It is unique in that it also allows you to apply security to these objects using a fairly simple but powerful scheme of users and groups. It's also unique in that for most objects, you will not need to write any code. All you need is a fairly simple configuration file, and you can have a class for your object ready to go, right out of thin air.
Velocity is a Java-based template engine. It permits anyone to use the simple yet powerful template language to reference objects defined in Java code. When Velocity is used for Web development, Web designers can work in parallel with Java programmers to develop Web sites according to the Model-View-Controller (MVC) model, meaning that Web page designers can focus solely on creating a site that looks good, and programmers can focus solely on writing top-notch code. Velocity separates Java code from the Web pages, making the web site more maintainable over the long run and providing a viable alternative to Java Server Pages (JSPs) or PHP. Velocity also provides template services for the Turbine Web application framework, making a template service that allows Web applications to be developed according to a true MVC model.
DbDesigner is a useful tool for constructing databases in an intuitive and easy-to-use environment, where you have a visual representation of the tables and relations contained in your project. You can quickly see the fields in a table or how each table relates to the others. After you are finished, it can export the schema of the database into an .sql script, or directly connect to a database backend and build it there. It can also import already existing databases from .sql scripts or db backends. It can save your project into its native format (XML) so all information is kept, and it has a plugin architecture to be easily extensible to work with many database servers (it comes with 2 plugins for PostgreSQL and MySQL).
