The present invention teaches in general how to efficiently exploit active database technology and extensible database technology, i.e. triggers and user-defined functions for processing subscriptions. According to a first aspect of the present invention it is proposed to aggregate all subscriptions on a certain table, or more generally of a plurality of tables, into a single trigger on this table or tables, respectively. This will dramatically improve the trigger-based efficiency. According to a second aspect of the present invention it is proposed to deliver the information a subscriber has registered for directly out of the database systems address space via appropriate user defined functions which is another source of efficiency improvement.
The present invention, known as the Middleware Brokering System Adapter, is a component useful with a Middleware Brokering System, which brokers messages between middleware computing products. Each middleware service can send data to and receive data from the Middleware Brokering System in its native data format and programming syntax. The Middleware Brokering System Adapter is a component of the Middleware Brokering System that transforms data messages from the native format of a middleware computing product or a mainframe computing system into a format known as a structured event and from a structured event into the native format of the middleware product or the mainframe system. In an embodiment of the invention, the Middleware Brokering System Adapter maps the fields of a Cobol copybook onto the fields of a structured event and the fields of a structured event onto the fields of a copybook. In an alternative embodiment, the Middleware Brokering System Adapter maps the fields of a Java Messaging Service MapMessage onto the fields of a structured event and the fields of a structured event onto the fields of a MapMessage.
The present invention relates to a system and methodology to facilitate timely delivery of notifications and performance of automated actions for users in the framework of an ad-hoc rules processing environment. An information agent operates as a distributed application to perform automated actions for users in accordance with user preferences and context. Various rules can be executed to delay, inhibit, and/or enable an action such as sending notifications according to the preferences and current user states as determined from the context. The rules can include data centric matching logic, set-oriented execution rules, rule ordering/interaction hierarchies, and ad-hoc Boolean combinations, for example.
The present invention relates to a system and methodology to facilitate development, debug, and deployment of a notification platform application. This includes providing various editor and display tools that interact with diverse components of the application in the context of a dynamic framework and development environment adapted to the nuances of the components. Visual displays and interfaces are provided that depict the various components of an application along with the relationships between the components. Developers are then directed though the components of the application in a visual manner, wherein various editors can be invoked to design a portion of the application relating to the selected component. Other aspects include providing a debug environment for troubleshooting a notification application along with deployment options to install and execute the application.
The present invention relates to a system and methodology to facilitate automated delivery of notifications to notification sinks while mitigating interface development and deployment within the framework of a notification platform. One or more message delivery channels are provided with the notification platform that can be associated with an extension component for delivering the notifications. The extension component automatically wraps an underlying message in a protocol associated with a notification sink such as wrapping a message post from a notification source within a common delivery protocol. The extension component can inherit delivery properties from an underlying platform interface associated with the delivery channels in order to mitigate coding and development details involved when utilizing or invoking the platform interface. Furthermore, the extension component enables various message protocols to be modeled as separate objects without having to implement higher-level or more complex aspects of the underlying interface.
The present invention relates to a subscription modeling system and methodology. A query processor receives subscription query and subscriber information and transforms the query and subscriber information into data. An index component propagates at least one database with the transformed data; and a matching component that associates the transformed data with event data to generate a database of notification data that can be delivered to subscribers. The invention provides for abstracting subscription and subscriber information (as well as event information if desired) to high-level classes (e.g., data fields)--thus the invention provides for modeling such notification related information as data. Subscription applications can thus be developed at high levels wherein complex subscription queries and subscriber information can be defined as data fields for example. Databases in accordance with the data fields can be propagated with subscription/subscriber specific information. The present invention takes advantages of the processing power associated with database engines (e.g., SQL server) to generate notifications via performing a join operation on the databases (e.g., subscription database(s), subscriber database(s) and event database(s)). Accordingly, notifications are generated en masse as compared to per subscription per subscriber. Thus the present invention provides for a highly scalable and efficient notification system.
