Oracle Training in Chennai – Advantage of Oracle Database

Oracle has many advantages and features that makes it popular and thereby makes it as the world’s largest enterprise software company. Oracle comes with new versions with new features implemented in new version while the features of earlier versions still being maintained. One important aspect is Oracle databases tend to be backwards compatible. Also when Oracle releases a new version, their documentation contains a list of all the features new to that version thus makes it user friendly for one to learn the new features.

Oracle takes a lead role because of some of the following reasons:

Oracle is used for almost all large application and one of the main applications in which oracle takes its major presence is banking. In fact ten of the world’s top 10 banks run Oracle applications this is because oracle offers a powerful combination of technology and comprehensive, pre-integrated business applications, including key functionality built specifically for banks.

Some similar databases like Sybase, SQL-Server one have facilities for using loops, conditions, arrays and so on in a program and also facilities like cursors and temp tables but all this would be used in a convoluted fashion which are very slow and resource consuming operations. The operations are not implemented as in Oracle which is efficient enough.

Also with the features available in oracle with the earlier versions in market the oracle company keeps upgrading and releasing new products into market, new versions releases which serves better than the earlier versions and thus the performance is improved much in later versions and thereby retaining the market growth and thus proves greater satisfaction to the customers using this technology. Thus the advantage of a higher version is that one would have more features and better capabilities.

For instance oracle 8i version has many new features which helped users namely like with oracle 8i one could run Java in the database, had features like new features on partitioning to support large database and so on. With the next version 9i oracle had these facilities maintained and had more new facilities added to it namely like new features added to help the DBA to handle change database configuration and so on.

Oracle is a database that responds very well with excellent performance in demanding environments. Oracle is a major database which along with its added features passes the ACID test, which is important in insuring the integrity of data. This is very important because data is the heart of any system in organization.

The following are the advantages of choosing Oracle Database.

Portability :
Prophet is ported to a greater number of stages than any of its opposition, running on more than 100 equipment stages and 20 organizing conventions. This makes composing an Oracle application genuinely safe from alters of course in equipment and working framework, and along these lines a sure thing. One proviso, then again, is that applications utilizing a few develops, (for example, field level triggers) may must be revamped while porting them to a square mode environment. You can likewise build up a decently completely included application with little information of the hidden OS. By and by, I have created applications on OS frameworks scarcely knowing how to duplicate and alter content documents.

Market Presence :
Prophet is by a wide margin the biggest RDBMS Vendor, and spends more on R&D than the majority of its rivals win altogether income. Prophet has the biggest autonomous RDBMS piece of the overall industry in VMS, UNIX and OS/2 Server fields. This business sector clout implies that you are unrealistic to be left hanging by Oracle and there are dependably bunches of outsider interfaces upheld furthermore, capable staff are generally simple to get.

Version Changes :
Prophet appear to be great at educating you in point of interest concerning what is not going to be upheld in the following real discharge and typically have some handle you can twiddle for good in reverse similarity, or just abandon it working, however with “don’t utilize this, utilization xxxx rather” notices in the manual. In reverse similarity is great significance you won’t be in for an application re-compose when you overhaul the DBMS. [Compare this with the Ingres v5->6 OSQL redesign from hell.] I’ve worked with Oracle since V4 Beta and have never been in for dreadful amazements to the extent sentence structure goes. On the other hand, see “Form Changes” under detriments.

Backup and Recovery:
Prophet gives modern quality backing to on-line reinforcement and recuperation and great programming adaptation to internal failure to plate disappointment. You can likewise do point-in-time recuperation. Obviously, you require the chronicle components and storage room to do this, yet Oracle underpins consistent filing to tape gadgets spreading over different volumes.

Performance :
Pace of a *tuned* Oracle database and application is very great, even with huge databases. Prophet allude to >100 GB databases and have individual experience managing 10 GB databases. The execution is “crude”, as well as incorporates thought of execution with locking and exchange control.

Cursor Support:
Prophet, similar to Ingres, yet dissimilar to Sybase (until Release 10 I think),supports cursors which simplicity programming when execution is required. A cursor fundamentally gives you a chance to do line by-line handling. Prophet underpins various cursors per Oracle association in accordance with ANSI guidelines.

SQL Dialect:
The tongue of SQL offered by Oracle is as I would see it better than the others in the augmentations it offers over ANSI-2, which is all that much a most minimized shared variable. Builds, for example, the outright capacity and decipher watchword are effective Oracle augmentations to the standard SQL.

Multiple Database Support:
Prophet has a better capacity than deal with various databases inside of the same exchange utilizing a two-stage submit convention. This is best executed in V7. You can reasonably effectively move where information is really put away from hub to hub in a system and have information reflecting, making it simple to advance the area of the information every now and then. This is not all that effortlessly finished with offerings from different merchants or prior forms of Oracle, where you were not ready to redesign more than one database in the one exchange with any dependability. This implied you couldn’t move information around without recoding your projects. With V7, your DBA can improve the area without pre-arranging by software engineers or reconsideration of the code preceding the move.

PL/SQL:
PL/SQL, the procedural augmentations, is a draft ANSI standard for procedural DBMS dialects. See primary examination on PL/SQL.

Declarative Integrity:
Prophet V7 onwards bolsters revelatory database uprightness (the current ANSI standard) and V6 grants you to enter the statements. With V6, you can get the toolset, (for example, SQL*Forms 3) to peruse the presentations and naturally produce the required code. With V7 onwards, not even this is required, as the database motor naturally authorizes the respectability. This implies you can open up your database to end-clients through basic outsider interfaces as they basically can’t break your business guidelines regardless of the possibility that they attempt. It makes it simple to oversee changes in business and information rules as there is one and only spot where the change should be made. This brings down the expense of obliged alteration to the framework in light of the fact that you don’t need to alter all applications code that works with the table.
