It allows organizations to place control of organization-wide database development in the hands of database administrators (DBAs) and other specialists. A DBMS is a system software package that helps the use of integrated collection of data records and files known as databases. It allows different user application programs to easily access the same database. DBMSs may use any of a variety of database models, such as the network model or relational model. Flat Files In database management, a...
The critical parts to a computer is everything that resides in the case, the motherboard, processor, Ram, Hard drive, and a power supply unit are the core fundamentals of a computer and general dictate how fast it will work. Other parts like graphics adaptors, sound cards, network adaptors are essential pieces if the computer is to be used for computer gaming. There are also several other input and out device that also help in the function of the computer, most importantly a VDU (visual display...
Introduction McWiLL is the most advanced broadband wireless solution provided by Beijing Xinwei Telecommunications Technology. The technology is based on SCDMA, and is known as Multicarrier Wireless information Local Loop (McWiLL). McWiLL combines SCDMA's traditional use in narrow-band voice and introduces a mobile broadband data service that ties into an IP-based core network. It is based on CS-OFDMA adaptive modulation, and uses dynamic channel allocation and smart antennas to enhance its...
ABSTRACT-: Commercial Off-The-Shelf (COTS) are pre-build components, developed by third party, available to the end user. COTS can either be hardware components or software applications. COTS applications include licensed, shareware and freeware software with commercial support. In recent times, use of COTS applications has increased largely due to their reduced cost and development time. In contrast to COTS applications, building customs software from scratch require a lot of time and...
In recent years, with the development of information technology, the operation of enterprises has gone through a drastic revolution. Data information flow became the lifeblood of enterprises. However, in such a situation, people would worry about disclosure of privacy and are likely to provide phony information rather than the authentic. So with the development of data analysis and processing technique, the privacy disclosure problem about individual or company is inevitably exposed when...
Strictly speaking, the database is in accordance with the data structure to organize, store and manage data warehouse. In the economic management of the day-to-day work, often need to put some data "warehouse", and in accordance with the management needs to be handled accordingly. For example, the basic situation of the personnel departments of enterprises or institutions often should the unit employees (employee number, name, age, gender, place of origin, wages, resume, etc.) are...
Internet flourishes around the world providing quick communication and countless amount of information. Data, video and voice, almost every single type of communication travels through internet. Some of this communication is private. The language of Internet is IP, the Internet protocol. Everything travels can, does travel over IP. One thing IP doesn't provide is security. IP packets can be interpreted, modified or captured on the route. Internet Protocol Security (IPSec) is a framework of...

In this chapter, the algorithmic robustness issue in geometric computation, including numerical robustness and geometrical robustness will be addressed. The main content will focus on two questions: the first is how non-robustness origins and the second is how to deal with the problematic robustness issue in geometric computation. Robustness is accepted simply to refer to programs', in fact the underlying algorithms', capacity to solve the problems in numeric computations or geometrical...
