A data processing center is as a place where various electronic equipment, computers, storage systems and telecommunications equipment located. As its name suggests, it is primarily used to treat the information necessary for the activities of a company.
For example, a bank may use such a center, entrusting the information relating to its customers, while handling transactions thereof. In practice, almost all medium-sized companies use a data center. For the larger companies, they often use several, including USB i2C.
Databases are often critical to business operations, they are very security sensitive. For this reason, these centers maintain high levels of safety and service in order to ensure the integrity and operation of equipment on site. Before the Internet bubble, millions of square meters to house such centers were built in the hope of seeing them filled by servers.
Concentration of centers has continued with the development of specialized facilities where the most important challenges are to control air conditioning and especially power consumption. This movement has been integrated into the green computing and aims to lead to treatment centers called ecological data centers.
Components
To handle the main tasks of the center, they must ensure proper network connection (internet). And high availability of the USB i2C information system. For this, different software applications support the essential duties of the customer business activity. Among these applications, there is database managers, file servers and application servers.
A data processing center can occupy one room, a floor or a large building. It includes 1U servers corresponding to a unit height of 4.445 cm (1.75 inch) stacked in racks, which are arranged to form single rows, which allows to move easily among servers, both front and rear. Some devices, such as mainframes, are of dimensions similar to those racks. They are often placed alongside them to augment USB i2C.
The database server performs the maintenance and management of the database and is responsible for the integrity and security of data, and also provides IO operations when accessing customer information.
Client-server architecture consists of clients and servers. The basic idea is to locate servers on powerful machines, and applications using the language component DBMS provide access to them with a less powerful client machines via external interfaces.
Most databases use SQL (Structured Query Language), as it is convenient to describe the logical subsets of the database. Creation of a database and a table with a full description of their structure. Perform basic data manipulation operations (such as insert, update and delete data from tables and USB i2C). Perform simple and complex queries.
