Answer» Among the most popular RDBMS systems are Teradata and Oracle: - Teradata: Teradata is an open-source RDBMS (relational database management system) that runs on different operating systems, including Windows, Unix, and Linux. The Teradata architecture is based on Massive Parallel Processing (MPP), and is therefore widely USED for large-scale data warehouse applications.
- Oracle: Oracle is a well-known Relational Database Management System (RDBMS), also referred to as Oracle database or OracleDB. OracleDB runs seamlessly on various platforms such as Windows, Unix, Mac, etc. Oracle was the first database DESIGNED exclusively for business and enterprise grid computing. As a result of REAL Application Clustering and Portability features, Oracle databases are SCALABLE to meet the demands of workloads. Enterprises choose it as a cost-effective solution to their application and data management problems.

| As this database is built on a shared-nothing architecture, the disks, Teradata nodes, and AMPs (Access Module Processors) are all independent and do not share resources with others. | Oracle architecture is based on Shared Everything architecture. | | In most cases, Oracle is used as an online backend application. It handles inserts, updates, and deletions in transactions in the database. | In most cases, Oracle is used as an online backend application.
