Abstract

A rule definition language (“RDL”) and a memory server are used to determine compliance with rules, such as rules used in determining compliance in securities trading. The rules, global data and local data are loaded into system memory of the server. The global datum consists of parameters or values used to determine compliance with said rules. The query, submitted to the memory server, contains the local data that is used to determine compliance of that query with the rules. The query is executed by accessing server memory to utilize the local datum and the global datum, such that the server determines compliance with the rules from the memory of the server. Syntax for the RDL, which permits programming in a manner particularly suitable for compliance checking procedures, is also disclosed.

and loading a plurality of global datum for use in executing said query comprises loading said global datum into said multiple dimensional associative array.

4. The method as set forth in claim 1, wherein the step of loading into system memory a plurality of rules further comprises the steps of:

receiving a rule definition language input that defines said plurality of rules; and

compiling said RDL input to generate said computer readable instructions.

5. The method as set forth in claim 1, further comprising the step of:

receiving periodically updated versions of said global data for use in executing said query.

6. The method as set forth in claim 1, wherein:

the steps of loading said global datum, said local datum and said rules into system memory of a computer comprises the steps loading said global datum, said local datum and said rules into system memory of a server; and

the step of receiving at least one query for determining compliance with said rules comprises the step of receiving said query from a client computer of said server.

7. The method as set forth in claim 1 wherein the step of loading a plurality of rules comprises the step of loading compliance rules for security trading.

8. A method for specifying rules in a computer implemented security trading compliance system, said method comprising the steps of:

providing a syntax in a rule definition language to declare at least one local variable in memory, wherein a local variable comprises a declaration for storage, in system memory, query data for temporary use of said query data during execution of a query; and

providing a syntax in said language to declare at least one global variable, wherein a global variable comprises a declaration for storage, in system memory, data resident for use during execution queries; and

providing a syntax through said language to declare pre-loaded memory tables.

9. The method as set forth in claim 8, wherein the step of:

providing a syntax through said language to declare pre-loaded memory tables comprises the step of further providing a syntax through a programming language to declare multi-dimensional associative arrays for accessing said multi-dimensional arrays.

10. The method as set forth in claim 8, further comprising the steps of:

providing a syntax to declare an operation comprising a plurality of Boolean operands to execute a plurality of variables; and

interpreting said syntax to execute Boolean operations subsequent to a final logical determination of said variables.

11. The method as set forth in claim 8, further comprising the step of providing a syntax to mark a function as mutually exclusive.

12. The method as set forth in claim 8, further comprising the step of providing a syntax to mark a function for execution a single time.

13. A computer readable medium comprising a plurality of instructions, which when executed by a computer, causes the computer to execute the security trading compliance steps of:

loading, into system memory of a computer, a plurality of rules, wherein said rules comprise computer readable instructions for execution in said computer, wherein a query comprises a plurality of parameters and wherein said rules comprise at least one statement for evaluating said parameters of said query;

loading, into said system memory of said computer a plurality of global datum for use in executing said query, including the steps of generating at least one pre-loaded memory table for storage in said system memory and loading said global datum in said pre-loaded memory table, wherein at least one global datum comprises parameters or values used to determine compliance with said rules for said query;

thereafter, receiving at least one query, for determining compliance with said rules loaded in said system memory, said query further comprising at least one local datum used to determine compliance of a corresponding query with said rules;

storing said local datum in said system memory of said computer; and

executing, in response to said query, said rules including accessing said system memory to utilize said local datum and said global datum, wherein said computer determines compliance with said rules from said system memory of said computer.

14. The computer readable medium as set forth in claim 13, further comprising the steps of:
