Abstract: Instructions are generated to manipulate target objects and relationships in a relational database when a source object having a one-to-many relationship of privately owned type with the target objects is manipulated. To generate instructions, mapping meta-data is used which contains information as to how object classes of the object model map to tables in the database and how relationships map to foreign keys.

Abstract: Methods and apparatus are provided for secure communication techniques in a communication system. The system can include a first device which communicates with a second device over a channel. A security association can be established during a first session between the devices via an asymmetric key exchange. The security association comprises a Traffic Encryption Key (TEK) and a first state vector. The TEK comprises a shared, secret symmetric key. The security association is stored in each of the devices for use during a second session between the devices to expedite security association establishment during call set-up of the second session. The security association can be associated with the second device in the first device, and with the first device in the second device. An updated state vector can be generated at the first device. A second session can be established between the first device and the second device by using the TEKs from the first session and the updated state vector.

Abstract: Techniques are provided for secure group communications in a wireless dispatch system which includes a group of devices. The group of devices can include a first secure device which communicates with a plurality of second secure devices over a channel.

Abstract: An apparatus (213) and corresponding methods (FIG. 7) to facilitate maintaining crypto synchronization while processing communication signals in a communication unit includes a vocoder (215) configured to convert input audio band signals to vocoder output frames; a crypto processor (217) configured to encrypt the vocoder output frames to provide encrypted output frames; and a synchronizer (219) configured to substitute in a predetermined manner synchronization information corresponding to an encryption state of the crypto processor for a portion of the encrypted data in a portion of the encrypted output frames to provide resultant output synchronization frames suitable for synchronizing a decryption process at a target communication unit.

Abstract: A retrieval system generates a retrieval query for batch reading of related objects when a source object is read from the database. The related objects include nested objects and/or many-to-many relationship objects. It generates a single retrieval query for each type in each level of nested objects using its parent query. Also it generates a retrieval query to retrieve a collection of target objects having many-to-many relationships with a collection of source objects.

Abstract: A system for integrating object changes occurring to an object in a first object storage system with a second object storage system. The system operates by first receiving from a first object storage systems a notification of an event relating to an object in the first object storage system. The system sets up a representation of the object in a second object storage system in response to the notification and determines object changes made to the object in the first object storage system by using the representation in the second object storage system. Finally, the system determines object changes with the representation in the second storage system.

Abstract: A system for integrating object changes occurring to an object in a first object storage system with a second object storage system is provided. The method comprises the steps of receiving from the first object storage system notification of an event relating to an object in the first object storage system, setting up a representation of the object in the second object storage system in response to the notification, determining object changes made to the object in the first object storage system using the representation in the second object storage system, and integrating the determined object changes with the representation in the second storage system.
