Oracle Database: Oracle Database Features

The rapid development of the information society entailed the development of various technologies designed to solve certain problems. One of the priorities was the need to design new ways of storing and processing 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.

What is a DBMS?

A database management system is a set of software tools used to create databases, as well as view, search and update stored information in them. Data arrays are managed using a set of linguistic and software tools. In practice, a DBMS is usually used to create information systems.

To date, several options for database management systems are available that distinguish both functionality and computer requirements. Examples of modern DBMS include Oracle Database, which will be discussed later, MySQL, Access, SQL Server, Fox Pro.

Despite the diversity of DBMSs, they are all divided into two types: multi-user and personal.

Multi-user systems

Such platforms are designed to perform complex tasks on powerful computers. In such a system, a lot of people work in parallel, so it consists of several elements, or rather:

  • core in memory;
  • Server
  • unlimited number of client programs that perform user-defined tasks.

In such a system, one main computer is used, which is used as a server and stores data and the kernel. Such a solution provides comfortable access for customers to the database. In addition, error correction is greatly simplified in such a DBMS. High speed data transfer makes work as efficient as possible. Clients can communicate with the system through any network. These are just some of the benefits of multi-user DBMSs, which include Oracle Database.

Personal systems

This type is designed to perform smaller tasks. The systems under consideration are located on personal computers and interact with one user. The database and the program itself are stored in the memory of one disk.

To date, the developers of such systems have added the ability to function in a network environment. However, in this case, the characteristic of each workplace is extremely important. Data is located on the server; all customers are required to install the application program and a copy of the system itself. But this solution causes problems when changing data. 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, then simultaneous access will be problematic.

Learn More About Oracle

What is an Oracle Database? For many years, Oracle DBMS provides 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 cannot do without using this DBMS.

Technologies are developing extremely fast, and new requirements are constantly being put forward for such products. Storing and interacting with data at the proper level provides several systems. But Oracle remains the leader due to continuous improvement.

Key Features

This DBMS is a set of software components whose capacity is enough to organize a project of any complexity. Well-designed scaling tools allow you to store databases an unlimited amount of information. Efficiency provides the ability to interact with data to any number of customers. A limitation can only be hardware resources. The developers implemented all the best server technologies in the system, making work through the Internet ideal.

An important feature is also the multi-platform Oracle. Linux, Windows and any other operating systems will effectively organize the database. Worth mentioning is the migration policy. The transition to updated versions is organized very conveniently, a special program will help transfer data from other systems.

What are the options for a DBMS?

Developers provide users with four system options:

  • Standard Edition
  • Lite
  • Enterprise Edition
  • Personal Edition.

This classification is not only found in Oracle Database. Versions are more similar to each other. The main differences are in the functional part, for each option there are unique options.

Standard edition

A very popular version, the functionality of which is somewhat limited. Most often it is used when creating systems for a small number of clients. This is the best option for a workgroup, small company, etc. But large organizations also have room for Standard Edition when it comes to remote branches. The price of this version of Oracle Database is reduced, while the available capabilities will be enough for efficient operation.

Oracle Lite

The most simple and lightweight version of the system. It is best used on mobile devices, laptops, etc. Convenient information synchronization is achieved through the use of common interfaces. Application development is carried out using standard tools.

Enterprise edition

The best version of Oracle DBMS with all existing features. 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 technology for storing and interacting with information. The database server will be able to work productively without stopping, thanks to the huge scalability. A wide range of tools will help to reserve data and, if necessary, restore it. Valuable information will never be lost.

Personal edition

This Oracle Database client is perfect 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 the options are available, and in 95/98 / ME the options are limited due to the features of the operating system.

Features of version 11g

Users often had problems installing this DBMS, and in version 11g this process was greatly simplified. In addition, it became more convenient to carry out not only initial, but also specialized setup. The system will become more efficient if it is optimized for the required task, and in Oracle Database 11g this aspect is well-developed.

Also improved scaling mechanisms. By adding new cluster nodes, you can achieve incredible performance in server speed and productivity. Now you do not need to stop programs or completely rewrite them. Stable operation of applications is not broken even if individual nodes break down.

How to get a DBMS?

On the official website you can download the desired version of the system, and this will always be the most competent solution. On the download page, you just need to study and confirm the license agreement, and then select the operating system.

The last step is authorization on the site. In the absence of a profile, you can easily create it and log in. 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.

Install Oracle 11g

How to install Oracle Database 11g on Windows 7? The DBMS is packaged in an archive, which after downloading will need to be unzipped.

Next, do the following:

  1. In the DISK1 folder, open the installation file called Setup.exe.
  2. Go through the welcome window.
  3. Agree to the license.
  4. Choose a place to install the program (but it is best to leave the path standard).
  5. Create a system administrator account.
  6. Check the indicated data and confirm it.

Installation is as simple as possible, and all the steps are intuitive. It is worth noting that not only on Windows it is so easy to install Oracle DBMS. Linux and all other operating systems will not cause problems either, since the deployment process is more identical.
