A MIDDLEWARE SYSTEM FACILITATING DEVELOPMENT, DEPLOYMENT, AND PROVISION OF STREAM-BASED SERVICES

摘要

A middleware system facilitating development, deployment, and provision of stream-based services is provided to easily develop a service and shorten the time of development by removing complicated stream connection and coding of a process part. A middleware system facilitating development, deployment, and provision of stream-based services includes a service arrange module(210), a stream handler(220) and a service operator(230). The service arrange module includes a service unit handler(212), a service unit registry(214) and a service unit activator(216). The service unit handler registers a developed service unit. The service unit registry stores the service unit. The service unit activator activates the service unit clarified in a service unit activating language. The stream handler includes a data stream receiver(222) and a buffer manager(224). The data stream receiver receives continuous data stream inputted from a stream provider(300). The buffer manager generates and manages a buffer for the data stream. The service operator includes a service unit instance manager(236). The service unit instance manager manages and executes a service unit instance.
