A Very High Level Programming Language for Data Processing Applications Application development today is too labor-in tensive. In recent years, very high-level languages have been increasingly explored as a solution to this problem. The Business Definition Language (BDL) is such a language, one aimed at business data processing problems. The concepts in BDL mimic those which have evolved through the years in businesses using manual methods. This results in three different sublanguages or components: one for defining the business forms, one for describing the business organization, and one for writing calculations.
