Oracle 19c PL/SQL 2 - Object-Relational Features TrainingOracle´s Object-Relational Features are intended for programmers developing new applications or converting existing applications to run in the Oracle environment. The object-relational features are often used in content management, data warehousing, data/information integration, and similar applications that deal with complex structured data. The object views feature can be valuable when writing new C++, Java, or XML applications on top of an existing relational schema. This training assumes that you have a working knowledge of application programming and that you are familiar with the use of Structured Query Language (SQL) to access information in relational database systems. The various parts of this training a) introduce the key features and explain the advantages of the object-relational model, b) explain the basic concepts and terminology that you need to work with Oracle Objects, c) discuss collection datatypes and operations on collection datatypes, d) explain object views, which allow you to develop object-oriented applications without changing the underlying relational schema, and e) explains how to perform essential operations with objects and object types.

Oracle 19c PL/SQL 2 - Object-Relational Features Seminar
General Concepts of PL/SQL and Oracle Objects

Overview of Object Orientation - Relational Mapping with PL/SQL - Object-Relational Structures

Object Types in PL/SQL and SQL

Introduction: basic principles of object types and objects, defining object types - PL/SQL objects in the Oracle database: create an object type, objects and SQL statements, objects in PL/SQL, object methods

Inheritance in PL/SQL

Inheritance and hierarchies in PL/SQL object types: Simple inheritance, overriding methods, substitution principle and dynamic binding, overloading, inheritance prevention - Abstraction: The principle of abstraction, substitution principle for abstraction, tables and inheritance, substitution principle for tables substitutability important SQL functions

PL/SQL Objects and PL/SQL Collections

Create collections using object types: use of VARRAYs, use of nested tables - Use of collections in tables: collection types, collections of primitive data type, DML operations - collections and objects in PL/SQL: use of collections and cursors, nested tables, collections, nested structures

Managment of Objects

Permissions and security: system privileges for PL/SQL object types, schema rights for PL/SQL object types - administration of objects: dependencies, synonyms, system views for objects

Object Views and OR-Mapping

Object Views and their use: general approach, nested structures - hierarchies and relationships, single-level hierarchies with collections, multilevel hierarchy with and without collections, relationships - working with Object Views: primary keys in views, NULL values??, references, inheritance, manipulation of data in views using SQL statements
