Using APL expressions in database operations

ABSTRACT

The Collateral Analysis System (CAS) is an analytic database written in Dyalog APL which combines the flexibility of a database with the power of a sophisticated analysis package. Much of the power and flexibility of CAS comes from the ability of users to create their own selection statements, calculations, and summary expressions.An expression is a combination of constants, fields and user functions which can form a selection statement, new field calculation, or frequency report specification.Users can generate tailor-made reports without programming. They simply enter expressions and format data and save the information with the database. Then, with the touch of a button, they can generate reports quickly and easily. CAS Expressions are merely APL expressions in disguise.
