Integration of Distributed Systems with Remote Servers over the Internet... 

The SSN estimated U.S. botanical sales in 1999 to be 4 billion. The network further quantified where consumers buy their botanical products. Forty-seven percent are sold in retail stores, 30% are sold in multilevel distribution systems, 8% are sold by mail order or practitioners, 6% was sold by Asian herbal shops, and only 1% was purchased on the Internet (13). Notwithstanding these findings, it is important to note that the Internet was the fastest growing sales market for botanical products, at 150% per year (45).

The FDA has been interested in Web enablement of computer apphcations. Several inspections questioned client controls for intranet and Internet access. The FDA also appears to be looking more critically at distribution systems for pharmaceutical and healthcare products. The MHRA has noted that validation requirements for distribution systems are generally not well understood and consequently the vahdation of these systems is often deficient. Distribution systems are vital components of the supply chain and companies should address their validation accordingly. In particular, focus should be placed on validating product return and recall processes. 

The business use of the Internet and electronic commerce enables online firms to reap the benefits of EDI at lower cost. The ultimate fast-response distribution system is instantaneous online delivery, a goal that a few e-businesses in select industries have already achieved. By their very nature, on-demand Internet audio and video services have no delay in reaching customers. In these examples, the efficiency stems from highly automated and integrated distribution mechanisms rather than from the elimination of distribution channels as in more traditional industries. 

A server located in a centralized place shall contain major information. It shall contain all the fields in the structure, but with or without full text of reports. This server shall contain the information that are required for execution of a search and the results are passed on to the user through Internet. Subsequently when the user asks for full text of the paper, it shall be made available to them. For storage of full text of reports, the servers containing the full text may remain distributed in the member countries. This distributed system will enable users to get all the information and at the same time satisfy the countries having classified information, the information is kept restricted and is available with them only. A pictorial representation of this arrangement is shown in Fig. 3. 

Oil and gas production systems, drainage networks, supply (delivery) networks, evacuation networks, flows of information on the Internet towards a common destination, wireless networks transferring information from Wi-Fi access points to a wired access point that coimect to the Internet, root network of plants, river basin systems, water distribution systems, the blood vessel system of animals, the morphology of the human limgs, certain data collection networks, etc. are all examples of flow networks with merging flows. In an oil and gas production system or a drainage system for example, the branches correspond to the components characterised by flow capacities while the nodes are notional, used to represent the topology of the network where the streams flow into another stream. 

At the highest strategic level, an organization can adopt either a proactive or a reactive approach toward product development. Which is appropriate depends on growth opportunities, protection for innovation, market scale, competition, and position in production and distribution system (Urban and Hauser, 1993). Since the Internet offers the potential to change these, one possible research question is how the advent of e-commerce may alter decisions about product development strategy (e.g., does it become more or less important to offer a stream of innovative new products as the web increases in importance as a marketing channel )... 

In distributed database architectures, the database is stored on several computers [6]. The computers in a distributed system do not have shared storage or main memory and communicate with one another through either high-speed dedicated networks or the Internet. The computers in this system may vary in size and function, ranging from workstations up to mainframes.

Underground cable plans are dealt with under Regulation 36. This is an important provision in the context of reducing the number of occurrences of underground cables being struck. The supply companies must maintain maps indicating the position and depth of cables and other elements of the distribution system and must make the maps available to anyone who can show reasonable cause. This includes local planning authorities and construction companies and utilities such as gas and telecommunication system suppliers. Some of the supply companies now hold their maps in electronic form and make them available via the internet.

While true parallel and multi-processor computers use much faster connections than IP protocol lines for internal communication, it is possible to simulate such systems using the Internet. Some spectacular computational feats have been achieved by coupling thousands of Internet-connected computers and using their idle cycles for the factorization of large numbers or, closely related, for the cracking of encryption schemes. Libraries for the setup of virtual parallel computers and cooperating distributed systems such as PVM (parallel virtual machine ) are readily available. 

Aleksandar Kuzmanovic is Lisa Wissner Slivka and Benjamin Slivka Chair in Computer Science and assistant professor in the Department of Electrical Engineering and Computer Science at Northwestern University. His work is in computer networking and distributed systems with emphasis on design, measurements, analysis, denial-of-service resiliency, and prototype implementation of protocols, algorithms, and large-scale systems for the Internet. 

The second type is the WAN (wide area network) installation. In this setup the LIMS take advantage of telecommunication technology to cover a great distance. The setup can also be used to connect disparate LANs together. In this configuration, the LIMS are installed on both the clients and a central server. The third type is the so-called centrally hosted thin client installation . For this setup, system administration is managed at a corporate center, where the LIMS are hosted and distributed via a WAN or the Internet with a virtual private network (VPN). The last and also the newest type is the ASP (Application Service Provision provider)-hosted installation. In this setup, the LIMS are hosted on a centrally managed server form and maintained by third-party specialists. Users access the LIMS with any Internet-connected PC with a standard Web browser.
