Encrypting sensitive credential data in the data dictionary is now enabled.You can now create schema-only accounts for object ownership without allowing clients to log into the schema.The Oracle Database Vault command rules protect the ADMINISTER KEY MANAGEMENT.In addition to the most common RDBMS features, the recent versions of the Oracle DBMS like 18C, 19C, and 21C come with the latest extra features listed below: As a multiuser RDBMS, the Oracle DBMS also manages transactions with the basic principle of “all or nothing” (an atomic operation succeeds or fails as a whole), while controlling data concurrency and maintaining data consistency.You can call PL/SQL programs through Java program units and call Java programs through PL/SQL. In addition, the Oracle DBMS allows you to save program units written in Java. The primary benefit of PL/SQL is the capability to store the application logic together with the database itself. You can use PL/SQL to control the flow of SQL programs, use variables, and write error-handling procedures using Oracle database SQL statements, functions, and data types. PL/SQL, a procedural extension to the Oracle SQL, is integrated with the Oracle database. Oracle SQL supports data access and many other features that extend beyond standard SQL.An Oracle database supports many schema objects such as tables, indexes, etc. As an RDBMS, the Oracle DBMS has database schemas (a collection of logical data structures).
It makes it possible to store complex business models in a relational database. It is an object-relational database management system (ORDBMS), which implements object-oriented features such as inheritance, user-defined types, and polymorphism.Let’s discuss a few RDBMS features of the Oracle DBMS. Many top companies, including JPMorgan Chase, UnitedHealth, and Citigroup, use this DBMS. It might be in your data center, in a public cloud, or in your private cloud. You can deploy your Oracle database wherever you want.Oracle uses a single database for all data types.Oracle guards your database against data breaches with security solutions for encryption, key management, privileged user access controls, data masking, monitoring activities, etc.And it provisions, scales, tunes, protects, patches, and repairs the database automatically without user intervention. It manages, secures, and maintains your database with automation driven by machine learning. According to the Oracle team, it reduces the operational cost by up to 90% from automation.Oracle has become a popular DBMS in the past couple of years for the following reasons: Oracle DBMS is a multi-model DBMS, and its secondary database models are the document store, the graph DBMS, the RDF store, and the spatial DBMS. Its primary database model is the relational database management system (RDBMS). Oracle is a widely used relational DBMS developed by the Oracle Corporation. These are my top database management systems based on their popularity: What you take away from this article will help you in selecting the best DBMS based on the nature of your database project. The popularity of a DBMS may depend on factors such as options for licensing, capabilities in common critical features, support by the best data modeling tools (i.e., Vertabelo), etc. There are hundreds of DBMSs in use in the modern database world, so it pays to know about the most popular DBMSs and their features, advantages, disadvantages, and their applications.
