ABSTRACT:
A system (10) for programming and performing applications programs in computer systems (70) using data in Structured Query Language ("SQL") data bases (32). Formulas (16) representing user defined tasks are constructed out of a formula sequence (18) of formula steps (20). Individual formula steps (20) are defined out of operand tokens (22 and 26), operation tokens (24), and result tokens (28). Operand tokens (22, 26) and result tokens (28) represent constants, variables, or SQL business objects, while operation tokens (24) represent precompiled members of a code modules library (36) that are capable of carrying out basic mathematical and data transfer operations on such operands (22, 26). Executing a formula (16) programmed with the system (10) in a computer system (70) is accomplished by dynamic allocation of resources such as memory work area (42), and loading operand token (22, 26) represented data along with the operation token (24) represented pre-compiled code of formulas (16) into the work area (42) where a processor (72) in the computer system (70) executes on the work area (42) contents and places the results into variables or into the SQL data base (32).
