The main difference between Oracle 11g and 12c is that Oracle 11g is an older version of Oracle RDBMS and does not have pluggable databases, while Oracle 12c is a newer version designed for the cloud and has pluggable databases. Additionally, Oracle 12c allows multiple databases to run on the same hardware while maintaining security and isolation between the databases.
DBMS (Database Management System) is software that helps create and manage databases easily and efficiently. An RDBMS is a DBMS that follows the relational model. In other words, these systems use a relational model to store data. They store data in tables, which are connected to each other. Oracle is one of those RDBMS. There are various versions in Oracle, Oracle 11g and 12c are two of them.

– Comparison of key differences
What is Oracle 11g
Oracle 11g is an RDBMS that is easy to install, manage, and develop. It consists of an intuitive browser-based interface for managing databases. Users can perform multiple operations using Oracle 11g. They can create tables, views, and other database objects. It is also possible to import, export and view table data. Users can write SQL queries and execute them to perform operations on database objects. Also, on this, it is possible to generate reports.
On the other hand, there are two versions in Oracle 11g; they are Oracle Database 11g Release 1 and Oracle Database 12g Release 2. Release 1 has Marquee features like Active Data Guard, Secure Files, and Exadata. Version 2 has Marquee features such as edit-based redefinition, data reduction, hybrid columnar compression, cluster file system, Golden Gate replication, and database appliance.
What is Oracle 12c
Oracle 12c is a high-performance, enterprise-grade RDBMS. It is Oracle’s first RDBMS designed for the cloud. Oracle Database 12c Release 1 provides an in-memory column store. It is an optional plugin that provides in-memory capabilities. The in-memory option provides real-time analysis. Oracle 12c also supports native JSON and SQL pattern matching.
One of the main advantages of this version of Oracle is that it allows users to move to the cloud more easily. On the other hand, it follows a multitenant architecture. And, this architecture simplifies consolidation without any application changes. Additionally, it provides pluggable databases to support rapid provisioning and portability. Therefore, Oracle 12c is suitable for self-service provisioning and database as a service. Oracle 12c Release 2 has native sharding, zero data loss recovery appliance, and Exadata Cloud Service.
Difference between them
Definition
Oracle 11g is a version of Oracle RDBMS released in 2008. Oracle 12g is a high-performance, enterprise-grade RDBMS version of Oracle released in 2014.
Version
Oracle 11g is the older version, while Oracle 12g is the newer version.
pluggable database
The main difference between them is that Oracle 11g does not have pluggable databases while Oracle 12c has pluggable databases. Additionally, Oracle 12c allows multiple databases to run on the same hardware while maintaining security and isolation between the databases.
multi-tenant architecture
Another important difference between them is that, in Oracle 11g, there is no multitenant architecture. But in contrast, there is a multi-tenant architecture in Oracle 12c.
cloud storage service
Cloud service is also a big difference between them. Oracle 11g does not have cloud support, while Oracle 12c provides Oracle Database Cloud Service.
memory capacity
On the other hand, Oracle 11g does not provide in-memory capabilities. However, Oracle 12c does provide in-memory capabilities.
JSON support
JSON support is another difference between them. Oracle 11g does not have JSON support while Oracle 12c does support JSON.
Performance
Additionally, Oracle 12c provides more performance in I/O throughput and response time than Oracle 11g. We can also consider this as a difference between Oracle 11g and 12c.
conclusion
Oracle 11g and 12c are two versions of Oracle. In short, the main difference between Oracle 11g and 12c is that Oracle 11g is an older version and does not have pluggable databases, while Oracle 12c is a newer version and has pluggable databases. Additionally, Oracle 12c allows multiple databases to run on the same hardware while maintaining security and isolation between the databases.
