Information Process
A merchant site that accepts electronic payments must include the following processing functions: (1) promotion; (2) welcoming; (3) payment; and (4) back-office.
Promotion
Successful implementation of a merchant site depends on a variety of factors, including site promotion. This can be done through fliers sent to the client or through fidelity programs. The promotion server can […]
The worldwide scope of an electronic commerce offer must rely on a set of physical and logical solutions to meet users’ expectations. Not all customers are computer wizards, and the architecture must account for ergonomic factors, in addition to the security of the exchanges and the different methods for accessing the telecommunications network. This section […]
Nevertheless, the transformation of the county fair into a supermarket is taking longer than originally anticipated. Use of the Internet for economic exchange clashes with the culture of freely available information, absence of a central authority, and the legitimate concerns regarding the security of information on the network. Security on the Internet is an afterthought; […]
The arguments in favor of the Internet sound, at a decade interval, like an echo of those that were previously formulated in praise of the Minitel. This passion for information technology is displayed in a context where ambitious growth rates are not physically sustainable, due to market saturation in rich countries, the progressive depletion of […]
The proliferation of incompatible payment systems creates difficulties for all concerned — users, service suppliers, financial institutions, and regulatory bodies. History has shown repeatedly that the expansion of commerce requires a stable and uniform environment. Yet, in a single aspect of electronic commerce such as electronic purses, there are more than 20 commercialized schemes in […]
The automation and dematerialization of monetary exchanges are not objectives per se, but are solely means to improve the productivity of financial institutions. In this regard, an overabundance of standards, and sometimes their competition, may constitute a barrier to the establishment of electronic commerce. Even if some manufacturers think they can profit from this situation, […]
The modern monetary system freed itself of material support by replacing it with a generalized system of trust based on continuous growth. In the past, monetary creation was absolutely limited by the scarcity of materials to be exchanged or of precious metals for minting coins. Now, however, money liberated from a material basis, in particular […]

How do we know if we have any rows in a table? We use the COUNT function to return a count of the number of rows in a table. If you enter Listing into Query Analyzer we can check the data insert for the Spy table.
This will return the current number of rows (well actually […]
The introduction of SQL Server 2000 enables us to have multiple instances of SQL Server running on a single machine. In the past we only had one instance of SQL Server, which in SQL Server 2000 is called the Default instance. Now we can have as many named instances as we want. Microsoft has tested […]

Indexes, like triggers, have always been a part of SQL Server but now we have even more features that we can take advantage of when creating indexes.
One of the biggest changes is allowing us to have an index on a computed column. A computed column is the answer from a sum. For example, consider a […]
User-defined functions (UDFs) rock! UDFs allow us to create compliant units of Transact-SQL that can return either a scalar value or a table.
A scalar value returns a single value (as our UDF did) of the type we specify in the CREATE FUNCTION statement.
A table returns a table of results. It leverages the new data type […]

The third screen you see (Installation Selection).
After you have completed this installation, if you want to modify the installation or remove it, you […]
Because it is usually implemented in a read-only memory (ROM) chip, the BOOTP protocol client is a simple, concise bit of code. The exchange of UDP messages between the client and the BOOTP server consists of a series of requests and replies. The same packet format is used for both types of messages with an […]
Even though diskless workstations are a small percentage of the total number of network nodes in the world today, the concept of receiving configuration information from a central server has not gone away. The Dynamic Host Configuration Protocol (DHCP) was developed after BOOTP as a means for providing a workstation (or any other network device) […]
Similar to BOOTP, DHCP uses a request/reply mechanism, and the packet format is almost the same for both to provide for backward compatibility. The layout of the packet used by DHCP looks very much like the layout of the BOOTP packet, with a few exceptions. The first 11 fields are the same. However, the last […]
Creating an Address Scope
After you have authorized a server on the network, you can create a scope of addresses that the DHCP server can administer to clients. From the MMC utility, click once on the server you want to administer, and then select New Scope from the Action menu. The New Scope Wizard pops up. […]
Installing a DHCP server on Windows 2000 or Windows 2003 Servers is just as simple as most application installs. However, you’ll need to have some information ready before you begin the installation. You will need to know the range of addresses that the server will administer and lease to clients. If you have any servers […]
