... Since the data model determines the database language of the system, which in turn determines the implementation of the system, we can understand that the differences between the various systems with different data models can be big and substantial. Second is the common theoretical framework. Although there is no standard object-oriented model, most object-oriented database systems that are operational or under development today share a set of fundamental object-oriented concepts. Therefore the implementation issues in OODBMSs that arise due to these concepts are universal. The third characteristic is that of experimental activity. Plenty of prototypes h ...

... Education or Special Education is instruction that is specially designed to meet the unique needs of children who have disabilities. This is done at no cost to the parents. Special education can include special instruction in the classroom, at home, in hospitals, or other institutions. Over 5 million children ages 6 through 21 receive special education and related services each year in the United States. Each of these children receives instruction that is specially designed: to meet the child's unique needs (that result from having a disability); and to help the child learn the information and skills that other children are learning (“Questions often asked ...

... and communicate. Individuals and businesses, from students and the media, to small business owners, programmers and corporate giants are all harnessing the power of the Internet. For many businesses the Internet is becoming integral to their operations. All users of the Internet have the ability to send and receive data: messages, notes, letters, documents, pictures, video, sound- almost any form of communication, as effortlessly as making a phone call. It is easy to understand why the Internet is rapidly becoming the medium of choice for business. Using the mouse on your computer, the easy point-and-click interface gives you access to electronic mail for sendi ...

... including access to the Internet. Some widely used on line services are Compu-serve, America On Line, and Prodigy. In the line of communication, these companies offer electronic mail, live conferencing, and allow users to converse with individuals. These services also provide large reference sections, including encyclopedias, libraries of all sorts, journals, newspapers, and magazines. They have databases consisting of airline fares, routes, and travel times, and allow for users to make flight reservations on line. Through on line services, users are able to check, buy, and sell stocks and bonds through brokers. The services provide entertainment t ...

... a router. The network has always recovered and bypassed the problem. The Internet began as the Advanced Research Projects Agency Network (ARPANET) during the cold war in 1969. It was developed by the US Department of Defense's (DOD) research people in conjunction with a number of military contractors and universities to explore the possibility of a communication network that could survive a nuclear attack. It continued simply because the DOD, DOD's contractors, and the universities found that it provided a very convenient way to communicate (Wendell). The ARPANET was a success from the very beginning. Although originally designed to allow scientists to share ...

... your eyes using a computerized facial template. The third camera takes a high-resolution photo of your eye, which the ATM then compares to a photo taken when you opened your bank account. If the two match, you can withdraw money. You won’t have to look into a viewfinder, or even open your eyes wider than normal. The cameras work at a range up to 3 feet away, and only take two to four seconds to find, photograph and match your iris. The security benefits are obvious: no two people, not even identical twins, have the same iris. While cards and PINs can be stolen, irises cannot. Van Naarden says iris-scanning is also being used overseas at teller windows, kiosks, v ...

... DOS,Windows, Lotus, Borland C++, dBase IV, and IBM LAN which are all copyrighted by The Canadian Copyright Act. The RCMP acted in response to concern from the users who stated that they were not sure whether this software could be distributed electronically. Yves Roy, sergeant of RCMP stated that charges will be laid in early December under paragraph 42 of The Copyright Act. Conviction under this act carries a maximum punishment of a fine of $1 million dollars, and/or 5 years imprisonment. Because newspaper articles are very biased in one point-of- view, it is difficult to look at both sides of this situation. But let us discuss piracy in a m ...

... or laser systems, the beam does not need to be level or parallel when it is placed under the vehicle The intelligence of the system automatically calibrates its position in relation to the points being measured. The system re-calibrates itself to the vehicle every time you measure. If you reposition the beam after the first measurement, or if the car moves, the beam will automatically re-calibrate from its new position, still producing the same measurement results. Before repairs, Shark provides you with the ability to prove existing damage. This information is good to the vehicle owner and insurance company because it not only explains the cost of repair ...

... represent information from voice, date, video and images, which allows for use with telephones, computers, and televisions. A strand of glass is thinner than a human hair, yet inch by inch is stronger than steel. The future of fiber optics is very promising due to the simple fact of how much information they can carry. Two single fiber optics lines carry the equivalent of 24,000 telephone calls at one time. With the introduction of fiber optics into our daily lives, it will greatly improve the quality and speed of the information we receive. With the growth of television and telephone traffic, bandwidth has become a large issue that is seemingly solved with the ...

... almost 2000 years ago. It is simply a wooden rack holding parallel wires on which beads are strung. When these beads are moved along the wire according to "programming" rules that the user must memorize, all ordinary arithmetic operations can be performed (Soma, 14). The next innovation in computers took place in 1694 when Blaise Pascal invented the first “digital calculating machine”. It could only add numbers and they had to be entered by turning dials. It was designed to help Pascal's father who was a tax collector (Soma, 32). In the early 1800's, a mathematics professor named Charles Babbage designed an automatic calculation machine. It was steam powered ...
