OpenEdge Advanced Business Language, or OpenEdge ABL for short, is a business application development language created and maintained by Progress Software Corporation (PSC). The language, typically classified as a fourth-generation programming language, uses an English like syntax to simplify software development. The name was changed in 2006 to OpenEdge Advanced Business Language (OpenEdge ABL), by PSC, from PROGRESS, a.k.a. Progress 4GL, in order to overcome a presumed industry perception that 4GL's were less capable than other languages. The language was called PROGRESS or Progress 4GL prior to the release of version 10.0. A subset of the language, called SpeedScript, is used in the development of web applications.
OpenEdge ABL helps developers to develop applications optionally using its own integrated relational database and programming tool. These applications are portable across computing systems and allow access to various popular data sources without having to learn the underlying data access methods. This means that the end-user of these products can be unaware of the underlying architecture.
By combining a fourth generation language and relational database, OpenEdge ABL allows the use of the Rapid Application Development (RAD) model for developing software. A programmer and even end users can do rapid prototyping using the integrated and GUI tools of the development environment.
