History of Oracle Database 12c

History of Oracle Database 12c

Oracle Database 12c, introduced by Oracle Corporation in 2013, marked a significant milestone in the evolution of database technology . As the first database designed for the cloud with a multitenant architecture , it transformed how databases are managed and accessed. The "c" in 12c stands for "cloud" and represents the company's commitment to enabling organizations to leverage the efficiencies of cloud computing.

This version brought revolutionary features like Pluggable Databases (PDBs) , which simplified the process of consolidating databases onto the cloud, thereby reducing IT costs and improving scalability . It also enhanced performance with In-Memory capabilities , allowing data to be processed with unprecedented speed.

Further developments included advanced analytics , robust security features , and improved data recovery processes. Oracle Database 12c has become a foundational technology for thousands of businesses, underpinning critical applications and systems.

Oracle's commitment to innovation ensures that Oracle Database 12c continues to evolve, offering high availability , flexibility , and efficiency in data management. It's a testament to Oracle's long-standing history of database leadership and technological excellence.

Recent Trends in Oracle Database 12c

Oracle Database 12c , an advanced and robust database management system, continues to evolve, providing cutting-edge features for cloud computing , data security , and performance optimization . The introduction of Multitenant Architecture has been a game-changer, allowing users to manage multiple databases as one, significantly reducing overhead and streamlining operations. In response to the increasing concern for data breaches, Oracle has enhanced its Advanced Security options, offering features such as Transparent Data Encryption and Data Redaction , which help protect sensitive information against unauthorized access. Moreover, Oracle Database 12c supports In-Memory Technology , which accelerates database performance for real-time analytics and transaction processing.Developments in machine learning and automation within Oracle's platform have also led to smarter database management and predictive analytics. These advancements not only improve efficiency but also empower businesses to gain insights faster. As organizations continue to migrate to the cloud, Oracle Database 12c remains at the forefront, offering seamless integration with Oracle Cloud services and other third-party cloud providers. Continuous updates and support ensure Oracle Database 12c users stay ahead in the ever-evolving world of technology.

Ans - No, the published fee includes all applicable taxes.

The c in Oracle Database 12c stands for cloud and depicts that database is cloud enabled.

The multi tenancy or multitenant architecture of Oracle Database 12c simplifies consolidation without introducing any kind of changes to the applications.

The multitenant architecture introduces the concepts of CDB (Container Database) and PDB (Pluggable Database).

CDB - Multitenancy allows users to have multiple virtual databases called containers. These containers exist inside one physical database called a container database (CDB).
PDB - The containers are easily plugged into or unplugged from the container database. Thus these containers are also known as pluggable databases (PDBs). The pluggable databases behave just like normal databases.

Oracle Database 12c was released initially in July 2013, and then the second release was done in September 2016 for the cloud and in March 2017 for on-premises.

The major differences include:

Oracle 11g allows users to create only one index on one column, while Oracle 12c enables users to create more than one index on the same column.
The Oracle 11g caching In-Memory Parallel Query does not work well with multiple scans whereas the new cache mechanism in oracle 12c, called as Big Table Cache, is used in improving the performance for full table scan.
Oracle 11g does not support full database caching while Oracle 12c completely supports full database caching to improve the performance for workloads previously restricted by response time or I/O throughput.
Oracle 11g does not support the In-Memory Aggregation concept while Oracle 12c does. In-Memory Aggregation support is extremely useful in star queries.
Unlike Oracle 11g, Oracle 12c contains invisible columns in the table. Invisible columns do not appear in generic queries and it is pretty easy to add or modify them.

Oracle 12c is indeed pluggable and this is one of the new and advanced features of 12c. A pluggable database, such as Oracle 12c, is a collection of schemas, schema objects and non-scheme objects that appear as an individual database.
