INTRODUCTIONIn This Introduction
Read this introduction for an overview of the information provided in this book and for an understanding of the documentation conventions used. About This Book
This book provides information to help you design, implement, and manage your Informix databases. It includes data models that illustrate different approaches to database design and shows you how to use structured query language (SQL) to implement and manage your databases.
This book is one of several manuals that discuss the Informix implementation of SQL. The Informix Guide to SQL: Tutorial, Second Edition shows how to use basic and advanced SQL and SPL routines to access and manipulate the data in your databases. The Informix Guide to SQL: Reference and Syntax, Second Edition provides reference information for aspects of SQL other than the language statements and contains all the syntax descriptions for SQL and Stored Procedure Language (SPL). Types of Users
This book is for the following users:
Database administrators
Database server administrators
Database-application programmers
This book assumes that you have the following background:
A working knowledge of your computer, your operating system, and the utilities that your operating system provides
Some experience working with relational databases or exposure to database concepts
Some experience with computer programming
If you have limited experience with relational databases, SQL, or your operating system, refer to the Getting Started manual for your database server for a list of supplementary titles.Software Dependencies
This book assumes that you are using one of the following database servers:
Informix Enterprise Decision Server, Version 8.3
Informix Dynamic Server 2000, Version 9.2Assumptions About Your Locale
Informix products can support many languages, cultures, and code sets. All culture-specific information is brought together in a single environment, called a Global Language Support (GLS) locale.
This book assumes that you use the U.S. 8859-1 English locale as the default locale. The default is en_us.8859-1 (ISO 8859-1) on UNIX platforms or en_us.1252 (
Microsoft 1252) for Windows NT environments. This locale supports U.S. English format conventions for dates, times, and currency, and also supports the ISO 8859-1 or
Microsoft 1252 code set, which includes the ASCII code set plus many 8-bit characters such as é, è, and ñ.
If you plan to use nondefault characters in your data or your SQL identifiers, or if you want to conform to the nondefault collation rules of character data, you need to specify the appropriate nondefault locale.
If you plan to use nondefault characters in your data or your SQL identifiers, or if you want to conform to the nondefault collation rules of character data, you need to specify the appropriate nondefault locale. Demonstration Databases
The DB-Access utility, which is provided with your Informix database server products, includes one or more of the following demonstration databases:
The stores_demo database illustrates a relational schema with information about a fictitious wholesale sporting-goods distributor. Many examples in Informix manuals are based on the stores_demo database.
The sales_demo database illustrates a dimensional schema for data-warehousing applications. For conceptual information about dimensional data modeling, see Chapter 10, "Building a Dimensional Data Model."
The superstores_demo database illustrates an object-relational schema. The superstores_demo database includes examples of extended data types, type and table inheritance, and user-defined routines.
For information about how to create and populate the demonstration databases, see the DB-Access User's Manual. For descriptions of the databases and their contents, see the Informix Guide to SQL: Reference.
The scripts that you use to install the demonstration databases reside in the $INFORMIXDIR/bin directory on UNIX platforms and in the %INFORMIXDIR%\bin directory in Windows environments.New Features
