The book has been written to provide students an excellent grounding in Database Concepts and Systems. The book has several illustrative examples, which have a logical link between them. Each set of examples helps build skills that will take the reader to the next set of examples, which in turn leads upwards until a strong programming foundation using ANSI SQL, the natural language of an RDBMS, has been established. The Topics Covered THE PURPOSE OF DATABASE SYSTEMS: Basic Database Concepts ENTITY RELATIONSHIPS MODELLING: E.R. Database Schemas THE RELATIONAL MODEL: Relational Algebra, Tuple Relational Calculus STRUCTURED QUERY LANGUAGE: Table Fundamentals, ANSI SQL Statements (DDL, DML, DQL, DCL), Data Constraints, The SET Operations, Views SQL TRANSACTIONS: Reversing Transactions, Cursors-Implicit And Explicit CONCURRENCY CONTROLS: Locking Protocol, Deadlock Handling, Locks QUERY OPTIMIZATION: Query Executed, EXPLAIN PLAN Command RELATIONAL DATABASE DESIGN: Decomposition And Normalization OTHER RELEVANT ADVANCED TOPICS AND APPLICATIONS ORACLE - FORMS: Creating A Data Entry Form Via The Forms Builder ORACLE - REPORTS: Creating A Report Via The Reports Builder. Each topic is liberally sprinkled with examples that are mapped to applications, which fit in the real world. At the end of each chapter there is a material review section consisting of Fill in the blanks and True or False questions. This should help in providing a quick but accurate way of measuring how the material has been absorbed. Where applicable each chapter has several Hands-on exercises. These exercises will help reinforce the concepts studied. The solutions to these hands-on exercises have also been provided at the very end of the book.
