10 reasons why Oracle is a leader in remote DBA solutions
Oracle database is a relational database management system (RDBMS) from Oracle Corporation. The Oracle DB was originally developed by Lawrence Ellison and other developers in 1977. Oracle DB is one of the most widely used and trusted relational database engines. This system is constructed around a relational database framework where data objects can be directly accessed by an application front end, or users through SQL (structured query language). The Oracle database has a network component that enables communication across networks. Here are the immense benefits of using Oracle RDBMS.
Oracle is ported to many more platforms than any of its competitors. It runs on more than 100 hardware platforms and just 20 networking protocols. As a result, writing an Oracle application is safe from any changes of direction in the operating system and hardware. One cautions however, is that applications that use some constructs should be reworked when porting them to block mode environments. One can also develop a fairly featured application with very little knowledge of the core operating system.
The speed of a tuned up Oracle database and the application is quite good, even when it comes to the larger databases. Oracle can accommodate databases greater than 100GB with ease. The performance of Oracle databases is not just raw, but it also includes consideration of performance with transaction and locking control. With Oracle, you will be assured of a database that performs at its peak at all times.
Multiple Database Support
Oracle has the ability to manage multiple databases within the same transaction with the use of a two-phase commit protocol. The V7 version implements this ability of Oracle best. You can easily move data from where it is actually stored; from one node to another in a network, and even have data mirroring. This makes it easy for you to optimize the location of the data or information from time to time. However, this is not done so easily with systems from other database vendors or other earlier versions of Oracle, where updating more than one database in a single transaction with reliability was not possible. This means that moving data around was not possible without the need for recording your programs.V7 allows Optimization of the location by your DBA without the need for pre-planning by the programmers, or for a re-examination of the codes before the actual move.
Oracle is quite good at informing users in detail about what will not be supported in their next major release. They also have some knob that users can twiddle for great backward compatibility or just leave it working. The manual has a warning about what you should not use, and what should be used instead. Backward compatibility is great because you will not need an application re-write whenever you upgrade your DBMS. This is an excellent advantage, especially for businesses that have a lot of information on their databases.
Just like Ingres, Oracle supports cursors that make programming easier when performance is needed. A cursor generally allows you to do processing row-by-row with ease. Furthermore, Oracle also supports multiple cursors for every Oracle connection which is in line with the ANSI standards. If you are looking for cursor support in your database management system, then Oracle is your best bet. Check out RemoteDBA.com for detailed information.
The SQL dialect that is offered by Oracle is more superior to other database management systems because of the extensions that it offers over the ANSI-2. This Oracle extension is by far one of the lowest common denominators. Furthermore, Constructs such as the decode keyword and absolute function are also very powerful additions of Oracle to the standard SQL. These powerful additions make Oracle far ahead of other database management systems in the market today.
From version V7 upwards, Oracle supports declarative database integrity that is now the current ANSI standard. In addition, V6 allows users to enter their declarations. With Oracle V6, you can also get toolsets such as SQL*Forms 3 that helps you in reading the declaration, and it will automatically generate the much required code. With the Version V7 upwards, this is not even required because the database engine tends to automatically enforce the integrity. This means that users can open up their database to the end-users using very simple third-party interfaces, but cannot sever your business rules no matter what. This makes it easier to administer any changes in your business and data rules because there is only one single spot where the changes should be made. This is good because it reduces the costs needed for modification of the entire system as users do not have to edit all their underlying application code.
Backup and recovery
Oracle offers industrial strength support for online recovery and backup. It also has an excellent software fault tolerance to any disk failure. In addition, you can also carry out point-in-time recovery. You certainly require the archive mechanisms and adequate storage space to do this. However, Oracle supports continuous archiving to tape devices that span multiple volumes.
Oracle is one of the largest remote database management systems vendors. Oracle spends more in R&D than its major competitions earn in total revenue. It also has one of the biggest independent RDBMS market shares in UNIX, OS/2, and VMS server fields, With this market clout, it is unlikely that anyone can be left out by Oracle. Furthermore, users will always have a lot of third party interfaces supported, and proficient staff that are quite easy to get.
Oracle DBMS is one the best database management systems in the market today. Oracle shines because of its security features. With powerful security features, you can be confident that your database will be secure from developers, DBAs and many more. Therefore, if you have anything that you want to keep off from the public eye, Oracle can help you secure it from anyone that you don’t want to see it including your system administrators and DBAs.
If you need a system that requires minimal or limited maintenance, then Oracle is an excellent option. This remote database management system comes with inbuilt diagnostics that help to monitor your performance. Furthermore, it offers automated patching for both software and firmware in a single operation. This means that with Oracle as your database management system, you will never have to worry about maintenance because you are covered.
