FOCUS

FOCUS is a computer programming language and development environment. It is a language used to build database queries, and is regarded as a fourth-generation programming language (4GL). Produced by Information Builders Inc., it was originally developed for data handling and analysis on the IBM mainframe. As newer systems were developed and smaller computers became more powerful, the available platforms for FOCUS were extended to personal computers and in 1997, to the World Wide Web in the WebFOCUS product.
