Oracle - what is it? Oracle Database

Many users, if not all, often deal with databases without even thinking about it. All websites, applications, games have their own bases. What it is? It's simple. This is collected information, which is organized in a certain way. A simple example is a phone book. Here there are names and surnames, numbers and, possibly, addresses. All this is ordered by some principle. For example, in alphabetical order.

In order to work with the database of this computer technology uses the management systems of these databases, which are called DBMS. One of the most famous is the tool from Oracle. What kind of systems and how they work, will be discussed further.

Features

The main thing that characterizes the products from this company is safety, reliability, convenience and very good performance. But these are not all characteristics that allow them to confidently lead the market for database management systems. Since information technologies are developing very quickly, the DBMS requires not only a classic set of functions that allow storing and processing data. Oracle is trying to keep up with the needs and gives its products new opportunities, thus breaking the stereotypes.

What is a DBMS?

Oracle - what is it? Modern DBMS is a very serious complex, which makes it possible to develop programs with incredible complexity. Well, the core of it is the database itself, in which information is stored. And its number, thanks to the provided scaling functions, can be unlimited. With this data, you can work as many users as possible, if the hardware capacity allows it . And the efficiency in this case does not fall at all. Even if the number of users increases dramatically, everything will remain stable.

The mechanisms that provide scaling in Oracle's latest versions of DBMS make it possible to increase the speed and power of the server and applications as much as you want. This is achieved by adding new nodes to the cluster. Stop running applications while not needed. Old applications that were developed for an architecture consisting of one machine, do not have to be reworked. In the event that there are problems with individual cluster nodes, the application still continues its work.

The fact that the Java virtual machine is embedded in the control system and full support for all server technologies has led to the fact that today Oracle is the database standard for the entire world wide web.

Support for all platforms

Multiplatform is another factor that makes the product a huge success. The DBMS is supplied for any operating system that exists on the market at a given time. And working with it on all platforms does not cause any problems, since everywhere everything is equally good.

So, those companies that are just starting to work with the company's products, there is no need to change their usual network environment. There are only a small number of differences in the operation of the database management system, which are determined by the peculiarities of the particular operating system. In general, one can say about Oracle that this is a convenient, reliable and secure system.

Transition to new versions

The company's migration policy does not raise any questions. Since the procedure of transition from an outdated version of the database to a newer one is a laborious process due to testing the work of existing programs in an updated environment, the company, issuing new versions of products, pays great attention to the compatibility of old and new versions. This makes the transition completely painless. If you want to transfer information from the database of other vendors to the DBMS from Oracle, the company can offer free tools to implement this procedure. This tool has a friendly user interface and will help you step-by-step through the entire data transfer procedure.

Versions that come out recently are very simple in their installation. The initial installation also does not cause any difficulties. Under the specific task of the possibility of special settings also increased. And with their help you can achieve tremendous results when working with the repository of information.

Versions

The database management system from Oracle comes in four different versions, among which there is even a lightweight mobile version, primarily designed for low-power desktop computers. But each version of the server is based on the same program code and is identical to its functions with others. There may be only a few options that are available only for a particular version and are not included in another version of the management system.

Enterprise Edition

Enterprise Edition is a full-featured DBMS. Its capabilities are limited only by hardware characteristics. In this version, in fact, there are all the newest developments responsible for the safe storage, processing and presentation of data to the user. Sufficiently wide range of scaling possibilities provides continuous operation of database servers around the clock, daily, all days of the year. Well developed and backup functions. With their help you can completely get rid of the risk of losing very important information.

Standard Edition

What is Oracle: the standard edition? This is a management system that has slightly reduced capabilities in comparison with the previous version. And this is reflected in the cost. This version is installed on servers that support only up to four processors. This option is the best solution for deploying an information system in a small organization, a working group or a single unit of a large enterprise.

Due to the fact that distributed type processing facilities are used and the data is replicated, the DBMS can be used with the support of work in such organizations that have a number of branches that are remote territorially.

Personal Edition

The personal version of the Oracle DBMS is a database designed for one user. It is used for training purposes and for developing and using programs for classic versions of the operating system from Microsoft. This option includes all the features of the Enterprise version. But for the operating system Windows 95 and 98 they are limited due to the impossibility of their implementation, since the old platforms do not know much.

Lite Edition

The Lite version is the most lightweight, mobile version of a database management system that allows you to synchronize information stored on weak computers and mobile devices with a corporate database. Access to them is provided through a standard interface. This allows you to make programs with the usual development tools.

So, we can say that the virtual machine Java and Oracle - it's very simple. With this bundle, you can manage huge databases with great comfort, and most importantly - it's safe. DBMS Oracle - what is this program? After the above, such a question should disappear. This is the best choice for both serious organizations and small firms.

By the way, the knowledge of this technology is a huge plus in the treasury of the applicant for the post of programmer. The requirements for vacancies often indicate the knowledge of Java, Oracle. What does it mean? All developers are somehow connected to databases, because all programs work with these same data.
