Ebus-J is a software development tool for the efficient development of professional commercial software in Java and Html.

Java knowledge is not required, BASIC knowledge is sufficient.

The basic principle of the Ebus-J is the machine independent development of any commercial software with the help of a program generator. Only the really individual parts of the program still have to be written by the software developer, everything else (that is up to 80% of the work) is done by the generator: program control, opening and closing the index files, screen control, printer control, etc.

At the press of a button you can create a Java single program, a Java Applet or a Java-Client-Server program in the 2-Tier model and by RMI, which is also internet-applicable. With 2-Tier programs a client- and a server program are created automatically, which communicate via RMI. The server program is executed by the Ebus-2T-Server, the client program runs on the user computer. Program processing of all clients takes place on the computer where the Ebus-2T-Server runs. Only screen data are transferred between client and server.

There is no knowledge of the 2-Tier model or RMI necessary. Neither is a special programming required since everything is done automatically by Ebus-J.

Ebus-J and the programs created by Ebus-J run on every computer that has Java 1.5 or higher.

The application of the EBUS-Generator-C has the following advantages:

• High-quality programs
• Drastic saving of time by fastness and efficiency
• Platform and database independency
• No restrictions: Any commercial program can be created
• Easy maintenance after later changes
• Protection of your investments for the future

The generator always creates the complete program as Java source code with every run of generation. Manual changes in the generated source code are neither necessary nor useful since all the changes would have to be made manually again with every new generation. All program changes can be carried out in the development environment of Ebus-J. The following tools can be used for this:

• Index file administration
• Mask editor
• Report editor
• A complete, easily learnable 4GL programming language (similar to BASIC) for the creation of individual program parts (macros).

The created Java source code is only a means to an end: It is only needed for the compilation and the creation of a fast, executable program.

The following restrictions apply to the demo version of the Ebus-J:

No more than 3 index files and 25 macros can be created.
A program cannot contain more than 3 masks and 1 report.
No more than 12 fields can be created on a mask.
No more than 25 data sets can be saved in the index files.

Set up the demo version by double-clicking the file setup_ebusjdemo.exe in the Explorer.

You need Sun JDK 1.5 to compile the generated java programs. You can download JDK 1.5 here:
