The popularity of the ESB has given rise to a number of commercial off the shelf (COTS) products as well as open source ESBs. In this study, we evaluated three open source ESBs and compared them both qualitatively and quantitatively. The empirical results were statistically tested to determine the statistical significance of the results.展开更多

First, the global standards of information exchange within power transmission and distribution area were evaluated, allowing the definition of state of the art on the theme, followed by determining its applications considering technologies already applied by the company. The specifications needed for the generation of a data integration model are adapted to radial overhead network at company concession area. The project developed an intermediary connectivity layer, based on the CIM （common information model）, which enables corporative systems to communicate in a standard way, through the use of integrating technologies. It, therefore, enabled modeling all main subjects of an electrical network in an open, extensible and non-proprietary way, in a model that contains classes and attributes of such subjects, as well as their relationships. Calculation and planning products adopted by the company were integrated to the technological layer implemented.展开更多

It is a key for successful diagnosis and treatment to view accurate and up-to-date patient data in a single information dashboard in real time. But the fact is that many hospitals and healthcare providers today are struggling with legacy system or internally developed systems that cannot easily scale to support new interfaces; the plethora of inflexible point-to-point interfaces make changing in one system deleteriously impact other systems; some systems could not support information sharing; and the standards followed by different systems are not compatible to each other. This is making it increasingly difficult to meet the rapidly changing and demanding of healthcare service.展开更多
