This section contains the following topics: Ingres Demonstration Application |

Ingres provides a sample transactional based application that demonstrates common programming tasks required to develop an application using Ingres.
The application shows how information is retrieved from Ingres and presented in a user interface control. Novice users can "borrow" code from the application to use in their own application development.
The demonstration application provides a working example of the main tasks required to insert, update, and retrieve data from an Ingres database, including:
|
|
|
The application developer should be familiar with the development language and environment, and somewhat familiar with SQL.

|
|
You can access the demonstration application if you opted to create and populate a demonstration database during the installation process.
When the application is started, it automatically connects to the database, demodb, on the local Ingres instance.
To start the demonstration application
Run IngresDemoApp.exe, located in the following directory:
%II_SYSTEM%\ingres\demo\xxxxxx\travel\app
where xxxxxx is the language, IDE, or software framework that the application is developed in. For example:
C# application: %II_SYSTEM%\ingres\demo\csharp\travel\app.
Eclipse Java application: %II_SYSTEM%\ingres\demo\Eclipse\travel\app.
Note: The source code for the application resides in: %II_SYSTEM%\ingres\demo\xxxxxx\travel\solution.

Each user interface control that displays data retrieved from an Ingres database has contextual help that includes instructions, source code, and query excerpts.
To display contextual help
The procedure for displaying contextual help depends on the application. For example:
C# Application: Press the help button 
in the upper right corner of the window, and then select a user interface control.
Eclipse Java Application: Press the help tab in the results part of the window, or press F1.
