Many users, if not all, often deal with databases without even thinking about it. All websites, applications, games have their own databases. What it is? Everything is simple. This is information collected that is organized in a specific way. A simple example is a phone book. There are first and last names, numbers and, possibly, addresses. All this is ordered according to some principle. For example, in alphabetical order.
In order to work with this database, computer technology uses control systems for these databases, which are called DBMS. One of the most famous is the tool from Oracle. What these systems are and how they work will be described later.
Features
The main thing that characterizes the products from this company is safety, reliability, convenience and very good performance. But these are not all the characteristics that enable them to confidently lead the market of database management systems. Since information technologies are developing very quickly, the DBMS requires not only a classic set of functions that allow you to store and process data. Oracle is trying to keep up with the needs and gives its products new features, thereby breaking 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, its core is the database itself, in which information is stored. And its quantity, thanks to the provided scaling functions, can be unlimited. Any number of users can work with this data, if the capacity of the hardware allows it . And the effectiveness does not decrease at all. Even if the number of users increases dramatically, everything will remain stable.
Scaling mechanisms in the latest DBMS from Oracle provide an opportunity to increase the speed and power of the server as well as applications as much as you like. This is achieved by adding new cluster nodes. Stop running applications while not needed. Old applications that were developed for a single-machine architecture do not have to be redone. In the event that there are problems with individual cluster nodes, the application still continues to work.
The fact that a Java virtual machine is built into the control system and full support for all server technologies has led to the fact that today Oracle is the standard DBMS for the entire world wide web.
Support for all platforms
Multi-platform is another factor that makes the product a huge success. The DBMS is supplied for any operating system currently on the market. And working with it on all platforms does not cause any problems, since everywhere everything is equally good.
So, for 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 caused by the features of a particular operating system. But in general, we can say about Oracle that it is a convenient, reliable and safe system.
Transition to new versions
The migration policy of the company does not raise any questions. Since the procedure of switching from an obsolete version of the database to a newer one is a laborious process due to testing the operation of existing programs in an updated environment, the company, releasing new versions of products, pays great attention to the compatibility of old and new versions. This makes the transition completely painless. If you need to transfer information from DBMSs of other manufacturers to DBMSs from Oracle, the company can offer free tools for implementing this procedure. This tool has a friendly user interface and will help you step-by-step to complete the entire data transfer procedure.
Recent versions are very easy to install. The initial installation is also straightforward. For a specific task, the capabilities of special settings have also increased. And with their help, you can achieve amazing results when working with a repository of information.
Versions
Oracle database management system comes in four different versions, among which there is even a lightweight mobile version, primarily designed for low-power desktop computers. But at the same time, each server option is based on the same program code and is identical in its functions to others. Only some options may be different that are available only for a specific version and are not included in another version of the control system.
Enterprise edition
Enterprise Edition is a fully functional DBMS. Its capabilities are limited only by hardware characteristics. In this version, in fact, there are all the latest developments that are responsible for the safe storage, processing and presentation of data to the user. A sufficiently wide range of scaling capabilities ensures uninterrupted operation of database servers around the clock, every day, 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: Standard Edition? This is a management system that has slightly reduced capabilities compared to 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 to deploy an information system in a small organization, work group or one unit of a large enterprise.
Due to the fact that distributed processing tools are used and the data is replicated, the DBMS can be used to support work in such organizations that have many branches that are geographically remote.
Personal edition
The personal version of the Oracle DBMS is a single user database. It is used for training purposes and in the development and use of programs for classic versions of the Microsoft operating system. This option includes all the features of the Enterprise version. But for the Windows 95 and 98 operating systems, 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 the database management system, which allows you to synchronize information stored on low-end computers and mobile devices with a corporate database. Access to them is provided using a standard interface. This allows you to make programs with conventional development tools.
So, we can say that the Java and Oracle virtual machine is very simple. With this bundle, you can manage huge databases with great comfort, and most importantly - safely. Oracle DBMS - what kind of program is this? After the above, such a question should disappear. This is the best choice for both serious organizations and small firms.
By the way, knowledge of this technology is a huge plus in the piggy bank of the job seeker programmer. Job requirements often indicate knowledge of Java, Oracle. What does it mean? All developers are in one way or another connected with databases, because all programs work with this very data.
