ATM Circuit extension technology enables service providers to map multiple VLAN to a virtual circuit, or to map multiple virtual circuits onto a single VLAN. Using this technology as a component, service providers can set up multiple point to point networks on ATM and Ethernet to provide enterprises with more flexible and scalable Ethernet based services.Conceptually, providing Ethernet services on an ATM n
In almost all other industries, cloud computing has been a revolutionary force in promoting system interoperability and reducing it costs, but it is hard to adopt a cloud model for healthcare it. Today, medical IT in the cloud is largely limited to small applications of managed electronic medical records (EHR) providers, such as Eclinicalworks and practicefusion. Instead of focusing on data exchange, these provide

The Apache Wink is rapidly growing into one of the standard implementations of the JAX-RS 1.0 specification. The providers for the JSON grouping and reconciliation group included with the Apache Wink version, such as json.org and jettison, have some problems with array representation, and the return type is relatively limited. It is difficult to write Jax-rs services and their customers asynchronous JavaScript and XML (Ajax) applications. In this arti

In the remainder of this article, I will focus on how to implement basic database operations in a ado.net manner. I want to explain when Ado.net is a better choice than ADO, and when you should give up ADO. Ado.net is not an improvement in ADO to conform to the. NET infrastructure. As long as you look at Ado.net's syntax, code design, and porting, you'll understand this.

functions from a dedicated provider through the network. In essence, software as a service is the computing power of the software that cloud computing service providers provide to meet users' specific needs. Saas-based cloud computing services have the following main features.
(1) users mainly use software services on the Internet through standard web browsers.
(2) Multi-tenancy ).
(3) users do not need to buy software. They only need to rent the sof
Cloud computingThere are at least 20 definitions of cloud computing so far, and a more common definition has been chosen:Cloud computing is a kind of distributed computing technology, the most basic concept is to automatically split the huge computational processing program into countless smaller sub-programs through the network, and then the large system composed of multiple servers is searched and analyzed and the results are passed back to the user. Through this technology, network service
B2B protocols (ebXML or RosettaNet) for mutual cooperation. When business partners exchange business information for business purposes, they participate in a session. A session is a series of business information exchanges between business partners. The session type (the session is complex or simple, long, or short) depends on the business purpose.
In addition to the B2B protocol, external users can also access enterprise services provided by Web Services.
