An intelligent framework is provided that is disposed between a high-level language environment and a database system environment. According to one embodiment, a software framework infers the need for one or more integrity constraints. The software framework programmatically receives (a) information regarding definitions of a multiple data structures associated with multiple objects participating in a software application, and (b) information regarding relationships among the data structures, where each object represents an instance of a data structure of the multiple data structures. Then, the software framework infers the need for one or more integrity constraints based upon the information regarding definitions of the data structures and the information regarding relationships among the data structures. Finally, the software framework instructs a storage system to apply the one or more integrity constraint.

Software framework that facilitates design and implementation of database applications

An intelligent framework is provided that is disposed between a high-level language environment and a database system environment. According to one embodiment, the framework programmatically receives information regarding definitions of data structures of objects participating in a software application and information regarding relationships among the objects. Based upon the particular request from the high-level language environment and upon the definitions and relationships, the framework programmatically and dynamically generates appropriate statements associated with the database system environment that accomplish the request. For example, the framework may issue statements to define the structure of a database, access information from the database, and/or manipulate information within the database.

A pneumatic carrier system is provided for distribution and transport of materials between different locations. The system includes a plurality of carriers for conveyance of materials and a control system for controlling the movement of the carriers in the system. The control system uses information associated with the carriers and the status of areas of the system to detect gridlock conditions which inhibit the movement of carriers. The system also includes bypass locations which are used to resolve detected gridlock conditions.

A conveyor system (10) is disclosed comprised of a plurality of vehicles (12), propelled about a guide track (14) by a D.C. motor (54) and battery (52), featuring an on-board control (40) in which signals from fore and aft and side mounted photosensors (32,34,36,38) are processed by a microprocessor (42), to generate control signals for pulse width modulated control of the power to the D.C. motor (54). The control signals are applied to a motor driver circuit (50), including an H-bridge of MOSFET switching components (Q1,Q2 A ramping or progressive variation of the power applied to the motor (54) is carried out to provide gradual acceleration or deceleration, and the fore and aft photo-detectors (32,34) are triggered by the approach of another vehicle (12) at a substantial distance, to accommodate the distance required for gradual deceleration when the vehicles (12) are being queued at points along the track (14).
