This book is about POSTGRESQL, the most advanced open source database. From its origins in
academia,POSTGRESQL has moved to theInternet with explosive growth.It ishard to believe the advances during the past four years under the guidance of a team of world wideInternet developers. This book is a testament to their vision, and to the success that POSTGRESQL has become. The book is designed to lead the reader from their first database query through the complex queries needed to solve real-world problems. No knowledge of database theory or practice is required.However, basic knowledge ofoperating system capabilities is expected,such ast he ability to type at an operating system prompt. Beginning with a short history of POSTGRESQL,the book moves from simple queries to the mostimportant database commands.Common problems are covered early,which should prevent
users from getting stuck with queries that fail.The author has seen many bug reports in the past
few years and consequently has attempted to warn readers about the common pit falls.
With a firm foundation established,additional commands are introduced.The later chapters
outline complex to pics like transactions and performance.
Ateachstep,the purpose of each command is clearly illustrated.The goal is to have readers
understand more than query syntax.They should know why each command is valuable,so they
can use the proper commands in their real-world database applications.
A data base novice should read the entirebook,while skimming over the later chapters.The
complex nature of data base systems should not prevent readers from getting started.Test
databases offer as a feway totry queries.As readers gain experience,later chapters will begin to make more sense.Experienced database users can skip the early chapters on basic SQL
functionality.The cross-referencing of sections allows you to quickly move from general to more spesific Information...........
