摘要： Systems and methods of storing and managing data, such as configuration data, in telecommunications systems and devices. The data are stored as objects, each data object having an associated type, and each object type having at least one instance of the data object. Each instance of each data object has a primary key field, which identifies that instance of the data object. Each instance of each data object can have zero or more foreign key fields, each of which can be used to make reference to the primary key of at least one other data object. By employing at least the foreign key fields and the primary keys of the respective data objects, various referential relationships, branching referential relationships, and many-to-many relationships among one or more groups of the object types can be defined and maintained, for use in storing and/or managing the data with increased flexibility and efficiency.

摘要： Systems and methods of performing real-time data subscription and reporting for telecommunications systems and devices. The systems and methods employ a real-time data aggregation component that can manage subscription requests for real-time data objects stored on the telecommunications systems and devices from one or more users over a network, dynamically start and stop such subscription requests, cache the requested real-time data objects, and supply the real-time data to the respective users. By employing the real-time data aggregation component to handle such subscription requests for data from one or more users, the systems and methods can supply such data, including real-time data, to the respective users, while reducing the overhead on the telecommunications systems and devices and increasing overall system performance.
