Progress
DataServer
for ORACLE Guide
Introduction
The DataServer for ORACLE allows you to access your ORACLE database with the Progress Fourth Generation Language (4GL) and develop applications within the Progress Application Development Environment (ADE). The ADE is a set of tools that helps you maintain databases and develop applications with graphical user interfaces. In addition to providing you with the ADE tools, the DataServer allows you to implement the Progress Version 8 database features and Progress 4GL expansions in applications that run with ORACLE. Some of these tools and features are:
- The AppBuilder — Use the AppBuilder to design and generate code for your graphical user interfaces. For example, you can use the AppBuilder to create a browser for viewing data stored in your ORACLE database.
- The Progress event-driven programming model — Use this programming model to develop applications that respond to choices that your end users make.
- The Data Dictionary — Use the Data Dictionary to modify database schema, create indexes, and define database triggers, validation expressions, and help messages.
- Database triggers — Use database triggers to fire a block of Progress 4GL code whenever a specific database event occurs, such as creating a record, deleting a record, or assigning a value to a field.
The DataServer for ORACLE does not support Progress word indexing.
The DataServer for ORACLE runs with ORACLE Version 7.3 and higher and Version 8.
This chapter presents an overview of the DataServer for ORACLE. It describes how Progress applications and databases work together with ORACLE through the DataServer. Specifically, it discusses DataServer architecture and guidelines for using the DataServer.
