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 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 Legal Wire tapping Works
CALEA requires that communications providers allow law enforcement officials to be able to listen in on phone conversations and get information about those phone calls, but only when the law enforcement agency has gotten approval for the tap.
The law enforcement agency goes before a judge and presents reasons a wiretap is […]
Throughout the history of the United States, one of the greatest political tensions has been that which balances personal privacy against the need for law enforcement to protect individuals and the country as a whole.
That tension has been with us from the very earliest days of the Republic. The Founding Fathers were extremely cognizant of […]
Creating a New User to Establish a Connection
Because this is a brand-new Web site, we do not have any users who can access our site. Remember when we created the SQLSpyNetUser?
Now we need to create a new user who has only limited rights. We don’t want anybody hacking the site, now do we?
Create a user […]
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 […]

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 […]

Tuning Indexes
The Index Tuning Wizard will assess your workload and give you suggestions for creating optimal indexes and statistics for your databases. The wizard […]
