The rapid development of the information societyentailed the development of various technologies designed to solve specific problems. One of the priorities was the need to design new ways to store and process large amounts of data using hardware.
The solution to this problem was the creation of databases (DB) as a means of storing information and database management systems (DBMS) as a processing method.
The database management system isa set of software tools used to create databases, as well as view, search and update stored information in them. The management of data arrays is carried out using a set of linguistic and software tools. In practice, DBMS is usually used to create information systems.
To date, several options are available.database management systems that distinguish both functionality and computer requirements. Examples of modern DBMS include the Oracle Database, which will be discussed later, MySQL, Access, SQL Server, Fox Pro.
Despite the variety of DBMS, they are divided into two types: multiplayer and personal.
Подобные платформы предназначены для выполнения challenging tasks on powerful computing machines. In such a system, many people work in parallel, so it consists of several elements, more precisely:
In such a system, one mainA computer that is used as a server and stores data and the kernel. This solution provides customers with comfortable access to the database. In addition, in such a DBMS error correction is greatly simplified. High speed data transfer makes work as efficient as possible. Clients can connect to the system through any network. These are just some of the benefits of multi-user DBMS, which includes the Oracle Database.
This type is designed to perform lesslarge-scale tasks. The systems in question are hosted on personal computers and interact with one user. The database and the program itself are stored in the memory of a single disk.
Today, the developers of such systemsadded the ability to function in a network environment. However, in this case, the characteristic of each workplace is extremely important. The data is located on the server; all customers are required to install the application and a copy of the system itself. But this solution causes problems when data changes. Access to the database in this case is also complicated. Each user works separately, and errors in his program are not visible to other clients. If they are not blocked, simultaneous access will be problematic.
What is the Oracle Database?For many years, Oracle's DBMS has provided users with maximum comfort, security, high speed and reliability. The system perfectly shows itself, and each of its features is important for the client. Most large-scale information systems can not do without the use of this DBMS.
Technologies are developing extremely fast, and forsimilar products constantly put forward new requirements. Storing and interacting with data at the proper level provides several systems. But Oracle DBMS remains in the lead, thanks to continuous improvement.
This DBMS is a set of softwarecomponents that have enough power to organize a project of any complexity. Competently developed scaling tools allow databases to store an unlimited amount of information. Work efficiency provides the ability to interact with the data of any number of clients. The limitation can only be hardware resources. The developers have implemented all the best server technologies in the system, making work via the Internet ideal.
An important feature also appearsOracle Multiplatform Linux, Windows and any other operating systems will effectively organize the database. It is worth mentioning the migration policy. The transition to the updated version is organized very conveniently, a special program will help transfer data from other systems.
Developers provide users with four system options:
This classification is found not only inOracle Database. Versions are more similar to each other. The main differences are in the functional part, for each option there are unique options.
Extremely popular version, the functionality of whichsomewhat limited. Most often it is used when creating systems for a small number of clients. This is the best option for a workgroup, a small company, and so on. But in large organizations, there is also room for the Standard Edition when it comes to remote affiliates. The price of this version of the Oracle Database is reduced, while the existing capabilities will be sufficient for efficient operation.
The most simple and lightweight version of the system.It is best to use it on mobile devices, laptops, etc. Convenient synchronization of information is achieved through the use of common interfaces. Application development is carried out using standard tools.
The best version of Oracle DBMS with all existingopportunities. This system has unlimited possibilities and allows you to organize absolutely any project. In this case, it all depends on powerful hardware. The version has collected the best storage technologies and interaction with information. The database server will be able to work productively without stopping, thanks to the huge scalability. A wide toolkit will help to reserve data and, if necessary, restore it. Valuable information will never be lost.
This Oracle Database client is great.for personal use or training. The functionality will be enough to create programs and their further use on several versions of Windows. They play an important role, since in NT or “2000” all possibilities are available, and in 95/98 / ME the options are limited due to the nature of the operating system.
Users often had problems withBy installing this DBMS, and in version 11g this process has been greatly simplified. In addition, it has become more convenient to carry out not only the initial, but also the specialized setting. The system will become more efficient if it is optimized for the required task, and in Oracle Database 11g this aspect is well developed.
Также улучшены механизмы масштабирования.By adding new cluster nodes, you can achieve incredible performance in server speed and productivity. Now you do not need to stop the program or completely rewrite them. Stable operation of applications is not disturbed even if individual nodes break down.
On the official website you can download the desired version.system, and it will always be the most competent decision. On the download page, you only need to examine and confirm the license agreement, and then select the operating system.
The last step is to authorize the site.If there is no profile, you can easily create it and enter the system. Having an account is not only mandatory, but also useful. In addition to the DBMS download page, users will have access to other interesting features.
How to install Oracle Database 11g on Windows 7? The DBMS is packed in an archive, which you will need to unzip after downloading.
Next you need to do the following:
Installation is as simple as possible, and all the stepsintuitive. It is worth noting that not only on Windows is it so easy to install a DBMS from Oracle. Linux and all other operating systems will also not cause problems, since to a greater extent the deployment process is identical.
