About DataWindow Designer
DataWindow Designer is a tool that creates DataWindow objects for use in
applications. A DataWindow object is an object that you use to retrieve and
manipulate data from a relational database or other data source. The following
DataWindow object retrieves and updates employee data.
DataWindow Designer provides built-in connectivity to a broad range of
desktop and server-based databases. It includes the EAS Demo DB (a Sybase
Adaptive Server® Anywhere database) to create reports and other
DataWindow Designer objects.
When you work in DataWindow Designer, you work in a graphical
environment—and working with data in this environment means you do not
need to understand SQL, the standard programming language for talking to
databases. DataWindow Designer creates all SQL statements behind the scenes
as you build your DataWindow objects and other objects graphically.
Painters
In DataWindow Designer, you do most of your work in the DataWindow
painter, where you “paint” your DataWindow objects. DataWindow Designer
also has painters where you work with databases, libraries, and SQL
statements.
The DataWindow Designer environment
When you start
DataWindow Designer
the first time
In DataWindow Designer, you always work within the context of a
DataWindow project. Information about the project is stored in a text file with
the extension .dwp. The DataWindow objects you create are stored in binary
files called libraries. Library files have the extension .pbl.
To create a new project and a library to hold your DataWindow objects, click
the New button on the PowerBar and select Project from the Project tab page.
