Virtual instruments is a program that implements functions of an instrument by software which could replace the work of real instruments to save resources. The functions of these sensor-based systems are limited and they commonly cannot manage related information, such as sensors and monitoring objects, due to special requirements. The procedure of development and integration often suffers from low...
Ocean environmental information service applications are widely adopted to assist collection, storage and distribution of ocean environmental data. Unfortunately, a reference framework rarely rules the development of those systems, leading to poor software quality and bringing many troubles in the process of maintenance and integration. This paper presents a common development framework which supports...
Software developments of Ocean Information Systems (OISs) have suffered from low efficiency and poor quality due to the absence of powerful software development models and methods. In this paper, the component-based development framework is proposed to facilitate OIS software developments. The framework consists of unified data model (UDM) and component development model (CDM). In the UDM, the classification...
