Abstract: This application describes a data stream processing system for receiving and processing multiple data streams using a stream join model and based on the stream join model having a threshold function for which an output of the stream join model crosses the threshold two or less times (e.g., where the threshold function is a convex function, linear function, monotonic function, or other function having a similar property). The data stream processing system may generate filtered data streams using a number of techniques and algorithms without risk of false negatives and mis2169sing instances where an output of a stream join exceeds or violates a threshold condition. The data stream processing system can significantly reduce processing expense, particularly in cases where one or more devices have limited memory and where caching tuples from incoming data streams consumes significant processing resources.

Abstract: The present disclosure relates to systems, methods, and computer-readable media for receiving and processing multiple data streams using a stream join model and based on the stream join model having a threshold function for which an output of the stream join model crosses the threshold two or less times (e.g., where the threshold function is a convex function, linear function, monotonic function, or other function having a similar property). The systems disclosed herein generate filtered data streams using a number of techniques and algorithms without risk of false negatives and missing instances where an output of a stream join exceeds or violates a threshold condition. The systems disclosed herein can significantly reduce processing expense, particularly in cases where one or more devices have limited memory and where caching tuples from incoming data streams consumes significant processing resources.

Abstract: In an interface-based object system capable of supporting multiple interfaces into objects, a relationship is defined as a pair of complementary collections on two separate interfaces, each interface found on separate objects. A link between objects is formed when an interface of one object lists an object supporting the related interface included in the object and vice versa. The collections may be of objects supporting the related interfaces or may be of specific relationship objects leading to objects supporting the related interfaces. The collections are potentially multi-valued entities that enable relationships to be established between objects using one-to-one, many-to-one, and many-to-many architectures. By implementing a specific relationship object, behavior may be imparted to the relationship itself thereby providing more robust system behavior.

Abstract: In an interface-based binary object system capable of supporting multiple interfaces into objects created by class templates, a relationship is defined as a pair of complementary collections on two separate interfaces, each interface found on separate objects. A link between objects is formed when an interface of one object lists an object supporting the related interface included in the object and vice versa. The collections may be of objects supporting the related interfaces or may be of specific relationship objects leading to objects supporting the related interfaces. The collections are potentially multi-valued entities that enable relationships to be established between objects according to one-to-one, many-to-one, and many-to-many architectures. By implementing a specific relationship object, behavior may be imparted to the relationship itself thereby providing more robust system behavior.

Abstract: An implicit session system with an object state cache. The implicit sessioning avoids explicitly passing session parameters in each function call to an object by implicitly associating the session context to a session object with each loaded object related to the session so that each function call runs with the session context of the called object. The object state cache minimizes the system resource impact of having multiple instances of an object in different sessions by sharing one copy of each respective unique object state in an object state cache.

Objects thus linked can be easily traversed so that convenient navigation models can be implemented allowing clients quick access to desired objects by navigating through relationships between objects.
