The document summarizes the contents and structure of a book on database management systems using Oracle SQL and PL/SQL. It is divided into three parts that cover fundamental database concepts, Oracle SQL programming, and advanced database topics. Part I focuses on database basics, modeling techniques, SQL queries and functions. It also addresses relational algebra, normalization and database security. The book includes over 300 examples, 400 questions, and 100 exercises to illustrate and reinforce the concepts. Instructors can access additional teaching materials on the publisher's website.

The book is organized into three parts to introduce the
theoretical and programming concepts of DBMS. Part I
(Basic Concepts and Oracle SQL) deals with DBMS basic,
software analysis and design, data flow diagram, ER model,
relational algebra, normal forms, SQL queries, functions,
sub‐queries, different types of joins, DCL, DDL, DML, object
constraints and security in Oracle. Part II (Application Using
Oracle PL/SQL) explains PL/SQL basics, functions,
procedures, packages, exception handling, triggers, implicit,
explicit and advanced cursors using suitable examples. This
part also covers advanced concepts related to PL/SQL, such
as collection, records, objects, dynamic SQL and
performance tuning. Part III (Advanced Concepts and
Technologies) elaborates on advanced database concepts
such as query processing, file organization, distributed
architecture, backup, recovery, data warehousing, online
analytical processing and data mining concepts and their
techniques.
