CASE STUDY;Fourth generation languages are even easier to use, and more English-like, than are third generation languages. Fourth generation languages are sometimes referred to as "nonprocedural", since programmes tell the computer what it needs to accomplish, but do not provide detailed instructions as to how it should accomplish it. Since fourth generation languages concentrate on the output, not procedural details, they are more easily used by people who are not computer specialists, that is, by end users. Many of the first fourth generation languages were connected with particular database management systems. These languages were called Query Languages since they allow people to retrieve information from databases. Structured query language, SQL, is a current fourth generation language used to access many databases. There are also some statistical fourth generation languages, such as SAS and SPSS. Some fourth generation languages, such as Visual C++, Visual Basic, or PowerBuilder are targeted to more knowledgeable users, since they are more complex to use. Visual programming languages, such as visual basic, use windows, icons, and pull down menus to make programming easier and more intuitive
