OpenEdge Advanced Business Language, or OpenEdge ABL for short, is a business application development language created and maintained by Progress Software Corporation. Typically classified as a fourth-generation programming language, it utilizes an English-like syntax to simplify software development. The language was called PROGRESS or Progress 4GL up until version 9, but in 2006, PSC changed the name to OpenEdge Advanced Business Language (OpenEdge ABL), in order to overcome a presumed industry perception that 4GLs were less capable than other languages. OpenEdge ABL helps developers to develop applications optionally using its own integrated relational database and programming tools. 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.
