OPERATING SYSTEM AND DATA BASE

摘要

A system for program development and execution consisting of a high level programming language based on a four part rule organization (31), consisting of a rule definition, a list of conditions, a list of actions taken upon satisfaction of a corresponding condition, and a list of exception handlers. Data access events are supplied through a table access method (21) which provides an interface to the variety of sources of data (22-30) coupled to the system. A table data store (103) organizes data in an object oriented, relational system, where each table is ordered on a primary key (502). The table access method (21) performs selection and ordering operations on the tables accessible through the table access method (21), implements and triggers invalidation routines upon data access events, and provides a common view of data stored across heterogeneous data stores coupled through servers (203-205) to the table access method (21). Ordered tables (103) are subdividable by additional parameters associated with table names.
