Oracle 2008: A New Era in Database Technology

Oracle Corporation, one of the world’s largest software companies, revolutionized the world of database management systems (DBMS) with the release of Oracle Database 11g in 2007. With the introduction of Oracle 2008, they have once agn taken the database technology to new heights. In this article, we will discuss the new features and improvements of Oracle 2008 that have made it a significant milestone in the history of DBMS.

Improved Security Features

Oracle 2008 delivers advanced security features to protect confidential data from unauthorized access or attacks. One of the most significant security features is Transparent Data Encryption (TDE), which encrypts data at the column level. This provides an extra layer of security to safeguard sensitive data agnst unauthorized access. Furthermore, user authentication and authorization are also strengthened with the introduction of the new Oracle Database Vault.

Improved Performance

Oracle 2008 has brought significant improvements in performance to meet the increasing demands of modern-day applications. In the past, the performance of database systems was determined by CPU and memory resources. However, Oracle 2008 has shifted the focus to storage performance, as it is becoming a bottleneck in modern-day applications.

Oracle Database 11gR2 uses Automatic Storage Management (ASM) to provide a fast, secure, and scalable storage infrastructure to enhance storage performance. Oracle 2008 also improves scalability by offering multi-node parallelism, allowing users to distribute execution across multiple nodes.

Efficient Management

Another significant improvement in Oracle 2008 is the Oracle Enterprise Manager’s cloud control that provides efficient and automated management of databases. With Oracle Enterprise Manager, database administrators can perform routine tasks such as backups, cloning, and patching without interruption to the production environment. Furthermore, it provides centralized management, which simplifies the management of multiple databases in a single location.

Support for Multitenant Architecture

Oracle 2008 introduces multitenant architecture, which allows multiple databases to share resources, reducing the cost and complexity of managing multiple databases. The multitenant database architecture supports one or more pluggable databases (PDBs) under a single contner database (CDB).

Conclusion

Oracle 2008 has brought significant innovations and improvements to database technology, making it a new era in DBMS. With advanced security features, improved performance, efficient management, and support for multitenant architecture, Oracle 2008 sets a new standard for the database industry. As technology continues to evolve, Oracle is committed to advancing the boundaries of the database technology to meet the demands of modern-day applications.
