Essential to database design, entity-relationship (ER) diagrams are known for their usefulness in data modeling and mapping out clear database designs. They are also well-known for being difficult to master. With Database Design Using Entity-Relationship Diagrams, Third Edition, database designers, developers, and students preparing to enter the field can quickly learn the ins and outs of data modeling through ER diagramming.
Building on the success of the bestselling first and second editions, this accessible text includes a new chapter on the relational model and functional dependencies. It also includes expanded chapters on Enhanced Entity-Relationship (EER) diagrams and reverse mapping. It uses cutting-edge case studies and examples to help readers master database development basics and defines ER and EER diagramming in terms of requirements (end user requests) and specifications (designer feedback to those requests), facilitating agile database development. This book
Describes a step-by-step approach for producing an ER diagram and developing a relational database from it
Contains exercises, examples, case studies, bibliographies, and summaries in each chapter
Details the rules for mapping ER diagrams to relational databases
Explains how to reverse engineer a relational database back to an entity-relationship model
Includes grammar for the ER diagrams that can be presented back to the user, facilitating agile database development
The updated exercises and chapter summaries provide the real-world understanding needed to develop ER and EER diagrams, map them to relational databases, and test the resulting relational database. Complete with a wealth of additional exercises and examples throughout, this edition should be a basic component of any database course. Its comprehensive nature and easy-to-navigate structure make it a resource that students and professionals will turn to throughout their careers.

A typical Oracle database has multiple users working simultaneously. Data is shared amongst the users, and this of course leads to security concerns. This book comes in from the angle of developing and maintaining a secure Oracle database with multiple users. The book shows how data can be shared in an orderly fashion and what a good secure database is. In this book, we assume that you are acquainted with basic Oracle SQL and fundamentals of relational database

Oracle is a widely used database engine. Due to its popularity, more and more schools and training organizations are using Oracle in their database courses to teach database principles and concepts. Given the current technological climate, the computer industry needs application developers who can write Oracle SQL code efficiently. This book employs a step-by-step systematic approach to learning Oracle SQL.

The current technological climate has generated a need for a concise book on Oracle/SQL programming tied to database principles and concepts. This book hopes to meet that need. It starts by presenting simple Oracle SQL concepts and slowly moves into more complex query development and PL/SQL. It also introduces SQL/XML. Each chapter includes numerous examples, which readers can assemble and execute themselves using Oracle. Each chapter ends with a series of exercises to reinforce and build on chapter material. In doing these exercises, we have provided a path for readers to learn SQL and the underlying principles of relational database.

Written for readers who have little or no previous experience with databases, SQL, or Microsoft SQL Server database software, this book provides a systematic approach to learning SQL (Structured Query Language) using SQL Server database software. It starts with simple SQL concepts, and progresses to more complex query development. Each chapter is written in a step-by-step manner and has examples that can be executed using SQL Server. Using the sample database, readers can experience hands-on SQL programming in SQL Server. This text also presents exercises at the end of the chapters to help readers gain proficiency in SQL.

This book, written for readers who have little or no previous experience with databases, SQL, or SQL Server, provides a very systematic approach to learning SQL (Structured Query Language) using SQL Server. Each chapter is written in a step-by-step manner and has examples that can be run using SQL Server. Using the sample tables and data provided, the reader of this book will be able to do all the examples to experience hands-on SQL programming in SQL Server. The text also presents a series of exercises at the end of the chapters to help readers gain proficiency with SQL. With this book you will learn: Beginning SQL commands how to retrieve and manipulate data using the simple SELECT statement. How to customize SQL Server 2008 s settings and about SQL Server 2008 s functions. How to create, alter, populate and delete tables. About joins, a common database mechanism for combining tables. Query development, the use of views and other derived structures. Simple set operations. About aggregate functions. How to write subqueries and correlated subqueries. How to create and use indexes and constraints. Transaction processing.

Anyone who interacts with today's modern databases needs to know SQL (Structured Query Language), the standard language for generating, manipulating, and retrieving database information. In recent years, the dramatic rise in the popularity of relational databases and multi-user databases has fueled a healthy demand for application developers and others who can write SQL code efficiently and correctly.
If you're new to databases, or need a SQL refresher, "Learning SQL on SQL Server 2005" is an ideal step-by-step introduction to this database query tool, with everything you need for programming SQL using Microsoft's SQL Server 2005-one of the most powerful and popular database engines used today. Plenty of books explain database theory. This guide lets you apply the theory as you learn SQL. You don't need prior database knowledge, or even prior computer knowledge.

Based on a popular university-level course designed by authors Sikha Saha Bagui and Richard Walsh Earp, "Learning SQL on SQL Server 2005" starts with very simple SQL concepts, and slowly builds into more complex query development. Every topic, concept, and idea comes with examples of code and output, along with exercises to help you gain proficiency in SQL and SQL Server 2005. With this book, you'll learn:

Beginning SQL commands, such as how and where to type an SQL query, and how to create, populate, alter and delete tables

How to customize SQL Server 2005's settings and about SQL Server 2005's functions

About joins, a common database mechanism for combining tables

Query development, the use of views and other derived structures, and simple set operations

Subqueries, aggregate functions and correlatedsubqueries, as well as indexes and constraints that can be added to tables in SQL Server 2005

Whether you're an undergraduate computer science or MIS student, a self-learner who has access to the new Microsoft database, or work for your company's IT department, "Learning SQL on SQL Server 2005" will get you up to speed on SQL in no time.
