Databases are the true workhorses of your company’s IT systems. And there is nothing more crucial than the proper maintenance of your workhorse. For that, many people choose one of the 3 leading DBMS products —Oracle, IBM DB2 and Microsoft SQL Server. If you are part of a large organization with a UNIX or Linux partition on the mainframe, Oracle is the primary choice for you.
Oracle is the automatic choice for most large corporations since it is the market leader on the Linux platform. The current version is OracleDatabase 12c that supports multiple versions of UNIX, Linux and Windows. There are a number of optimized tools for database administration that aid efficient data management and migration. With the widespread use of Oracle, finding a good Oracle technician with a wide range of skill-set isn’t as difficult today.
In sync with modern tech
Oracle is the choice of most successful companies and enterprises due to its efficient database management options and security options. Although Oracle is known to be notoriously costly, it is definitely one of the best DBMS products in terms of efficient database administration and application. Oracle has a whopping 40.8% market share in Europe with IBM coming in second with a distant 29.4%.
The truth about Oracle everyone should know
We know, many of you are already thinking it. So let us just come out and say it. Oracle is not the most elegant DBMS and not always the fastest either. But in the early 90s, it had successfully carved out a niche for itself in the relational DBMS product spheres. Oracle is not constrained like Informix is to UNIX. Oracle has the reputation of being the most versatile database product in the current market especially since it runs on 60 odd platforms. Oracle is also one of the most advanced DBMS platforms that have gained the status of trendsetter.
For example, back at the OracleOpenWorld 2006, we were promised a stunning number of new features — 482 to be exact in the upcoming database servicesfrom Oracle. While a few of them are understandably minor, quite a number of them are profound. These include query result caching, capture and relay of DB workloads and multiple upgrades.
The most common arguments we get to hear from an Oracle competitor or an Oracle-hater include the following:
- Oracle is expensive – yes, we agree that Oracle can be more expensive than quite a few DBMS products. But it is definitely worth the money. In addition to being the best in its domain, Oracle now offers free Oracle XE to give MySQL a run for its money.
- Oracle is complex – well, Oracle is flexible yet strong too. People who have trained for years as an OracleDBA reap tantalizing rewards in terms of paychecks and perks. No one really cares how complex the product is as long as it is the best in its department. With 11g Oracle has taken customization to a new level. You can literally tell Oracle how much memory it can use at a time and how much to dedicate to PGA and SGA. It has enabled users to use a single storage pool for managing several databases.
Justifying the “Why Oracle” questions:
These are questions that skeptics have been asking us for decades now. Oracle has a mélange of best features that can be customized and implemented on your company database. To sum up, the best Oracle database features are:
- It reduces both server and storage costs.
- It eliminates the idle redundancy in all data centers.
- It increases the productivity of DBAs and improves all system performances.
Oracle actually allows the users to select database products according to immediate requirements. The most common product variations include Express Edition, Standard Edition and Enterprise Edition. These are compatible with platforms ranging from Mainframe to Mac.
Comparing Oracle with SQL Server
- Oracle Database is the main data administration arrangement that is demonstrated to scale to meet all business prerequisites on all equipment stages, from single processor and mid-run multiprocessor frameworks to large scale.
- SQL Server only runs on the Windows stage, so any future development of a business is then additionally constrained to the Windows stage.
- Oracle Database gives exceptional movability over every significant stage, and guarantees that your applications will pursue without adjustment not withstanding evolving stages.
- SQL Server is of course limited to only the Windows platform, and has no technology for supporting a grid architecture.
- Oracle Database is the most cost effective database for ensuring minimal downtime and zero data loss. It takes care of most scenarios that might lead to data unavailability, such as system failures, data failures, disasters, human errors
- SQL Server does not provide equivalent functionality at the equivalent cost for handling system failures or data protection.
MAA (Maximum Availability Architecture)
- Oracle Maximum Availability Architecture (MAA) is Oracle’s best practices blueprint based on proven Oracle high availability technologies, expert recommendations, and customer experiences. The goal of MAA is to achieve optimal high availability for Oracle customers at the lowest cost and complexity.
- While SQL server also follows ‘High Availability and Disaster Recovery’ architecture, Oracle has an upper edge owing to its higher platform and environment flexibility as compared to SQL server.
What is the role of an Oracle DBA in a company?
A DBA or database administrator is the key to all company data. He is given the responsibility of structuring and archiving the company data. He must understand all the basic rules of a relational database system like the relational OracleDBA. Here are his most important responsibilities:
- The DBA must maintain the data about the data. This is technically metadata that needs to be collected, stored and supplied as per query. Any data stored without a description or metadata lacks true meaning. The DBA is responsible for maintaining all metadata about archived data for all future references.
- Any good DBA must be able to convert a data model into a physical database implementation. Very rarely does that physical model completely conform to the logical model, but the DBA must maintain the physical form and see that it bears all the nuances of the DBMS used by the company or organization.
- The DBA is also responsible for performing SQL code reviews and walkthroughs to improve DBMS efficiency and performance speed. Writing new programs to build new tools for efficient database management and function is also a part of an OracleDBA’s job description. He is a key participant in a production turnover and management.
- The DBA must also see to the proper backup of all data for each database file. This usually depends on data volatility. This is an integral part of the data migration system that in supervised by the DBA.
To summarize, the main aim of any DBA is to ensure the availability of valid data at all times.
All in all, Oracle is currently the leading RDBMS (Relational Database Management System) vendor and that makes it much easier to find proficient OracleDBAs who have years of training and experience in working for companies. Having a DBA is a must for any large company that needs to curate data and with Oracle you get the best value for your money. Oracle offers a 360-degree support that is quite unseen in the other RDBMS products.
