A database management system (DBMS) is a software package with computer programs that control the creation, maintenance, and the use of a database. It allows organizations to conveniently develop databases for various applications by database administrators (DBAs) and other specialists. A database is an integrated collection of data records, files, and other database objects. A DBMS allows different user application programs to concurrently access the same database. DBMSs may use a variety of database models, such as the relational model or object model, to conveniently describe and support applications. It typically supports query languages, which are in fact high-level programming languages, dedicated database languages that considerably simplify writing database application programs. Database languages also simplify the database organization as well as retrieving and presenting information from it. A DBMS provides facilities for controlling data access, enforcing data integrity, managing concurrency control, recovering the database after failures and restoring it from backup files, as well as maintaining database security.

products online. It also includes the entire online process of developing, marketing, selling, delivering, servicing and paying for products and services. The amount of trade conducted electronically has grown extraordinarily with widespread Internet usage. The use of commerce is conducted in this way, spurring and drawing on innovations in electronic funds transfer, supply chain management, Internet marketing, online transaction processing, electronic data interchange (EDI), inventory management systems, and automated data collection systems.

电子商务,通常被称为电子商务、电子商务或e-comm,指买卖产品或服务的电子系统,如互联网和其它计算机网络。然而,该术语可能不仅仅指购销产品在线。它也包含了完整的在线过程开发、营销、销售、传送、技术服务和支付的产品和服务。电子贸易的数量增长了非常广泛互联网的使用。使用商业活动,刺激和借鉴创新电子资金划拨、供应链管理、网路行销、联机事务处理、电子数据交换(EDI)、库存管理系统、自动数据采集系统。现代电子商务一般采用万维网至少在一个点在事务处理的生命周期,尽管它可能包括更广泛的技术,如电子邮件、移动设备和电话。
Electronic commerce that takes place between businesses is referred to as
business-to-business or B2B. B2B can be open to all interested parties (e.g. commodity exchange) or limited to specific, pre-qualified participants (private electronic market).

Many of these soldiers could not withstand the epidemics of measles, mumps, and whooping cough that went through the camps. Army life was hard. Soldiers got few fruits or vegetables. There was no milk unless they happened to find a cow. Neither their clothes nor their shelters protected the troops from rain, snow, and cold. Sickness and disease were spread by insects, rats, and impure drinking water. Often the men drank straight from muddy streams. Gunshot wounds were serious, as in any war,

They are more powerful and reliable and, importantly, are very economical in terms of energy consumption. Their presence opens a new era in the field of IT technologies and means that the cloud technology is getting closer. These processors are primarily designed for servers, data centers (DPC) and supercomputers. The emergence of this class of devices is not accidental. According to the regional director of Intel in Russia and other CIS states Dmitri Konash who spoke at the event, the market of IT-technology is developing so rapidly that, according to forecasts, by 2015 there will be 15 billion devices connected to the Internet, and over 3 billion of active users. 上周，英特尔公司向俄罗斯和其它独联体国家的公众推出了英特尔Xeon E5-2600系列处理器，它们更加强大可靠，尤其是在能量消耗方面更加经济实惠。它们的问世意味着IT技术领域开始了一个新时代，标志着云技术距离我们越来越近。 这些处理器主要是为服务器、数字处理中心和超级计算机设计的。这种处理器的出现并非偶然。根据英特尔公司俄罗斯和其他独联体地区负责人Dmitri Konash就此事发表的看法，IT技术市场的发展速度极快，根据预测，到2015年与英特网连接的设施将有150亿，用户超过30亿。 [Ex 6] 1.
