Write a Review
"Most reliable DBMS in the world"
Strengths: 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.
Pros (Advantages): Following are the fringe benefits of the Oracle DB.Data consistencyIntegration of dataEasy file generationTo increase securityEasy updating of recordsRemove data redundancyTo reduce wastage if timeEnforcement of standardsControlled data redundancyReduce the total expendituresSearching of particular data is easyTo get rid of heavy files and registers workThe work of three persons should reduce to oneInstant intimation of modification of information
Weaknesses: Cons (Disadvantages): Following are the fringe drawback of the Oracle DB.Oracle DB is useful only for large organization.Number of concurrent users.Budget for both hardware and RDBMS are expensive.Takes longer to learn the entire application and not as simple. Less qualified professionals available.Out of the box doesn’t perform as well.If any bugs are occur, than you can’t found easily.Oracle DB is not very good in parallel servers.
Comments: In terms of the competition:
The technology industry is based on larger firms buying smaller ones. Competition authorities should rightfully be concerned only if it harms consumers in general, not whether it harms a particular subset of users. Various others appear to believe that the Database market is hopelessly consolidated and were Oracle to get its hands on the copyright to the MySQL source code that would be bad for competition. This, to be honest, completely and utterly disregards the actual history of the database market, which has always been one of consolidation and benefits to the consumer:
1. Illustrate, a Berkeley spinout, was bought by Informix
2. Informix was bought by IBM.
3. Redbrick was bought by IBM
4. RDB was bought by Oracle
While this consolidation has reduced the number of vendors in the market, as of 2007 there was still pretty hefty competition with Oracle even then only with a 44.1% share of the paid database market. As someone who has had to work professionally with Oracle, DB/2, Sybase, and Microsoft SQL/Server, I can say this is almost certainly because it's the best overall product. Furthermore, those numbers in terms of the database revenue are completely suspect (with the exception of Microsoft's). There's a huge amount of revenue for IBM and Oracle which are tied to services and software sitting on top of the database (such as Oracle applications and IBM services), and realistically the CFOs of each company can tune the percentage of the deal that goes to the underlying database based on what numbers they want to report. The overall deal may be $1MM, but the sales person has a lot of discretion on how they price the database component.
