Progress—The Flexible and Complete 4GL
The Progress 4GL excels in seven main areas, all supported within the language:
- Flexibility — Rapid application development and testing
- Consistency — Integration of user interface, database, and logic with a single language
- Security — Multi-user access control and data management
- Interoperability — Interfaces to and from external and remote programs and systems
- Connectivity — Access to databases in local and client/server configurations
- Portability — Development and deployment on multiple platforms
- Localizability — Development and deployment support for national languages
The following sections describe these major language areas and where to find more information on them. Later sections in this chapter describe the syntax and structure of a 4GL application and how to build one.
