Oracle Database and its Features

What is Oracle?

Oracle Database Corporation offers the Relational DBMS system known as Oracle DB (Oracle DB). Since its founding in 1977 by Lawrence Ellison and other programmers, Oracle DB has become one of the most reputable and commonly used databases for the storage, organisation, and collecting of data by type as well as for the upkeep of relationships between different sorts.

Users may directly access data objects (or an application front) in the system thanks to a relation database framework and a structured query language (SQL). Worldwide businesses that handle and manage data over extensive local networks frequently use Oracle, a highly scalable relational database architecture. To enable communication across the network, the Oracle database has a network component.

Oracle DB also referred to as Oracle RDBMS and, on occasion, just as Oracle. The most popular operating systems, including Windows, UNIX, Linux, and macOS, support Oracle DB. The Oracle database is compatible with a number of Oracle operating systems, including IBM AIX, HP-UX, Linux, Microsoft Windows Server, Solaris, SunOS, or macOS.

What are the features of the Oracle database?

Security:

Data security is always of utmost importance. Oracle has put in place procedures to control who may access and use data. It is possible to offer users with diverse access by authorising and altering user behaviour.

Backup and Recovery:

The robust data recovery procedures built into the Oracle architecture can restore data after almost any kind of failure. The database has to swiftly restore in the case of a failure for high availability. While the compromised data is being recovered, portions of the data that have not been corrupted are still available.

Scalability and Performance:

Real Application Clustering and Portability are two characteristics of Oracle databases that make them scalable dependent on usage. In a multiuser database, which Oracle takes into account, it is vital to control data consistency and concurrency.

Availability:

Real-time applications need high data availability. Data availability always guaranteed by high-performance computing environments. In both anticipated and unanticipated outages and failures, data is accessible.

Market Presence:

Oracle is by far the biggest provider of RDBMSs, and it spends a lot more money on R&D than its rivals. In terms of RDBMS market share, Oracle dominates the VMS, UNIX, and OS/2 server sectors. There are relatively little chances that Oracle will leave you hanging because there are so many third-party interfaces provided. You will be able to get more assistance since qualified people is easily accessible.

Large database and Space Management:

Oracle is capable of supporting the largest databases. You have total control over how much room you take up, which enables you to make the most of your equipment.

Portability:

Numerous systems can run Oracle software after it is been ported. Applications created by Oracle may port to many operating systems without needing to be modified.

Manageable security:

In order to prevent unauthorized database access and usage, Oracle offers fail-safe security tools to restrict and track data access.

Controlled availability:

Oracle furthermore provides a wonderful function known as managed availability at all levels (even at sub-level). For instance, the administrator can stop specific programmes from being pack or load without affecting other applications.

Distributed systems:

Oracle allows for local database management while employing distributed systems, despite the fact that non-distributed solutions don’t offer the same level of user transparency and data consistency as distributed systems.

What are the benefits of oracle?

Due to its features, Oracle enjoys an edge over its rivals. We’ll now examine Oracle’s advantages.

Good performance:

 It has principles and methods in place to aid in your attaining excellent performance. By applying speed optimization in the database to retrieve and alter data more quickly, we may improve query execution time and consequently application activities.

Several Databases:

 The management of several database instances on a single server makes possible by its database. To keep track of CPU usage on a server running database instances, Oracle offers the instance caging mechanism. Instance caging and database resource management collaborate to manage services across several instances.

Editions:

Oracle offers a number of editions, letting users to choose the one that best suits their requirements. They may easily update the edition if their demands alter in the future. Download and install the free express edition database if you wish to learn Oracle and practise your skills.

Clusters:

To provide a system with high data availability, it takes advantage of Real Application Clusters. The database with RAC offers the following benefits over regular database servers:

• The database scales via many instances.
• The process of balancing referred to as load balancing.
• Redundancy and availability of data
• Flexibility will increase processing capacity.

Failure recovery:

During outages or downtime, you may recover or restore database files using RMAN (Recovery Manager), an Oracle database utility. Along with archival backups and ongoing archiving, it supports online backups. User-managed recovery, which is also possible, uses SQL* PLUS and is available to users. An export tool for adding user-managed backups is present in the database.

What are the disadvantages of oracle?

Complexity:

The complexity of Oracle Database is one of its main drawbacks. Oracle is not advised, especially if the users lack the technical know-how and proficiency necessary to work with the Oracle Database. Oracle is also not suggested if a business or individual wants a database that is easy to use and offers fundamental functionality. It requires specialised knowledge to set up and maintain because it is a very complicated engine and cannot simply be installed and used.

Managing Difficulty:

Oracle is far more complicated and challenging to administer when it comes to managing individual activities. The professional recommendation is to install the basic version first, then customise it with the least amount of modification possible. Only when large databases are needed are they useful, says Oracle Database. For small or medium-sized organisations that need only a few modest databases, Oracle is not advised. The best choice in this case would be MySQL because it is more affordable.

Oracle Database Price:

Oracle products can cost up to ten times more when compared to the MS SQL Server Database Solution for a mid-range solution. Customers are thus more inclined to select other, less expensive options, such as installing MySQL without charge or utilising any of the several engines in an AWS solution for a little fee. Furthermore, the cost of an Oracle licence does not fix since it changes over time based on a number of factors, including corporate policies, patches, and upgrades.

Versatility:

You can manage your data on any operating system thanks to Oracle SQL. Only internal systems from a single manufacturer are compatible with dedicated languages. For instance, Microsoft SQL Server can only use with a Windows-based computer. In contrast, if you install Oracle SQL on a UNIX server, you’ll benefit from UNIX’s reliability while still upholding the requirements of SQL. Your data keeps safe because UNIX is less vulnerable to a wide range of common computer viruses. Oracle SQL is also backward-compatible, allowing you to upgrade in the future without losing any data.

Oracle database editions:

Windows, UNIX, Linux, and Mac OS X are just a few of the systems that the Oracle database is compatible with. It is capable of running a variety of operating systems, including macOS, Linux, Microsoft Windows Server, Solaris, and HP-UX. In the late 1990s, Oracle started offering support for open systems like GNU/Linux.

The following is a priority-ordered list of Oracle database editions:

Enterprise Edition:

 The software’s most reliable and secure version is this one. It has all the bells and whistles, including enhanced security and performance.

Standard Edition:

For people who do not need the entire bundle of the Enterprise Edition, this edition offers the necessary functionality.

Express Edition:

Express Edition (XE) is a lightweight, free, and constrained version of Windows and Linux.

Oracle Lite:

 A mobile-friendly version of Oracle is also called Oracle Lite.

Personal Edition:

 Although Personal Edition lacks Oracle Real Application Clusters, it is comparable to Enterprise Edition.
