Learning Perl, 4th Edition

Learning Perl, 4th Edition
Brian D Foy, Randal L Schwartz, Tom Phoenix | O'Reilly Media | 2011-07-10 | 704 pages | English | PDF

"Learning Perl, better known as "the Llama book," starts the programmer on the way to mastery. Written by three prominent members of the Perl community who each have several years of experience teaching Perl around the world, this edition has been updated to account for all the recent changes to the language up to Perl 5.8.

Perl is the language for people who want to get work done. It started as a tool for Unix system administrators who needed something powerful for small tasks. Since then, Perl has blossomed into a full-featured programming language used for web programming, database manipulation, XML processing, and system administration--on practically all platforms--while remaining the favorite tool for the small daily tasks it was designed for. You might start using Perl because you need it, but you'll continue to use it because you love it.

Informed by their years of success at teaching Perl as consultants, the authors have re-engineered the Llama to better match the pace and scope appropriate for readers getting started with Perl, while retaining the detailed discussion, thorough examples, and eclectic wit for which the Llama is famous.

The book includes new exercises and solutions so you can practice what you've learned while it's still fresh in your mind. Here are just some of the topics covered:

Perl variable types

subroutines

file operations

regular expressions

text processing

strings and sorting

process management

using third party modules

If you ask Perl programmers today what book they relied on most when they were learning Perl, you'll find that an overwhelming majority will point to the Llama. With good reason. Other books mayteach you to program in Perl, but this book will turn you into a Perl programmer.

M.rgan K..fmann | 2011 | ISBN: 0123820200 | 352 pages | File type: PDF | 10 mb

Database systems and database design technology have undergone significant evolution in recent years. The relational data model and relational database systems dominate business applications; in turn, they are extended by other technologies like data warehousing, OLAP, and data mining. How do you model and design your database application in consideration of new technology or new business needs?

In the extensively revised fifth edition, you'll get clear explanations, lots of terrific examples and an illustrative case, and the really practical advice you have come to count onwith design rules that are applicable to any SQL-based system. But you'll also get plenty to help you grow from a new database designer to an experienced designer developing industrial-sized systems.

In-depth detail and plenty of real-world, practical examples throughout

Loaded with design rules and illustrative case studies that are applicable to any SQL, UML, or XML-based system
Immediately useful to anyone tasked with the creation of data models for the integration of large-scale enterprise data.

Marcelo Arenas, Pablo Barcelo, "Relational and XML Data Exchange"


Marcelo Arenas, Pablo Barcelo, "Relational and XML Data Exchange"
M.rgan and Cl.ypool Publishers | 2010 | ISBN: 1608454118 | 112 pages | File type: PDF | 1 mb

Data exchange is the problem of finding an instance of a target schema, given an instance of a source schema and a specification of the relationship between the source and the target. Such a target instance should correctly represent information from the source instance under the constraints imposed by the target schema, and it should allow one to evaluate queries on the target instance in a way that is semantically consistent with the source data. Data exchange is an old problem that re-emerged as an active research topic recently, due to the increased need for exchange of data in various formats, often in e-business applications. In this lecture, we give an overview of the basic concepts of data exchange in both relational and XML contexts. We give examples of data exchange problems, and we introduce the main tasks that need to addressed. We then discuss relational data exchange, concentrating on issues such as relational schema mappings, materializing target instances (including canonical solutions and cores), query answering, and query rewriting. After that, we discuss metadata management, i.e., handling schema mappings themselves. We pay particular attention to operations on schema mappings, such as composition and inverse. Finally, we describe both data exchange and metadata management in the context of XML. We use mappings based on transforming tree patterns, and we show that they lead to a host of new problems that did not arise in the relational case, but they need to be addressed for XML. These include consistency issues for mappings and schemas, as well as imposing tighter restrictions on mappings and queries to achieve tractable query answering in data exchange.

Full Description:

"PHP and MySQL have changed. Back in 2001, when I wrote the first edition of this book, readers were astonished to discover that you could create a site full of web pages without having to write a separate HTML file for each page. PHP stood out from the crowd of programming languages, mainly because it was easy enough for almost anyone to learn and free to download and install. The MySQL database, likewise, provided a simple and free solution to a problem that, up until that point, had been solvable only by expert programmers with corporate budgets.

Back then, PHP and MySQL were special—heck, they were downright miraculous! But over the years, they have gained plenty of fast-moving competition. In an age when anyone with a free WordPress account can set up a full-featured blog in 30 seconds flat, it’s no longer enough for a programming language like PHP to be easy to learn; nor is it enough for a database like MySQL to be free.

Indeed, as you sit down to read this book, you probably have ambitions that extend beyond what you can throw together using the free point-and-click tools of the Web. You might even be thinking of building an exciting, new point-and-click tool of your own. WordPress, after all, is built using PHP and MySQL, so why limit your vision to anything less?

To keep up with the competition, and with the needs of more demanding projects, PHP and MySQL have had to evolve. PHP is now a far more intricate and powerful language than it was back in 2001, and MySQL is a vastly more complex and capable database. Learning PHP and MySQL today opens up a lot of doors that would have remained closed to the PHP and MySQL experts of 2001.

That’s the good news. The bad news is that, in the same way that a butter knife is easier to figure out than a Swiss Army knife (and less likely to cause self-injury!), all these dazzling new features and improvements have indisputably made PHP and MySQL more difficult for beginners to learn.

Worse yet, PHP has completely abandoned several of the beginner-friendly features that gave it a competitive advantage in 2001, because they turned out to be oversimplifications, or could lead inexperienced programmers into building web sites with gaping security holes. This is a problem if you’re the author of a beginner’s book about PHP and MySQL.

PHP and MySQL have changed, and those changes have made writing this book a lot more difficult. But they have also made this book a lot more important. The more twisty the path, the more valuable the map, right?

In this book, I’ll provide you with a hands-on look at what’s involved in building a database driven web site using PHP and MySQL. If your web host provides PHP and MySQL support, you’re in great shape. If not, I’ll show you how to install them on Windows, Mac OS X, and Linux computers, so don’t sweat it.

This book is your map to the twisty path that every beginner must navigate to learn PHP and MySQL today. Grab your favorite walking stick; let’s go hiking!

Who Should Read this Series?
This article series is aimed at intermediate and advanced web designers looking to make the leap into server-side programming. You’ll be expected to be comfortable with simple HTML, as I’ll make use of it without much in the way of explanation. No knowledge of Cascading Style Sheets (CSS) or JavaScript is assumed or required, but if you do know JavaScript, you’ll find it will make learning PHP a breeze, since these languages are quite similar.

By the end of this series, you can expect to have a grasp of what’s involved in building a database driven web site. If you follow the examples, you’ll also learn the basics of PHP (a server-side scripting language that gives you easy access to a database, and a lot more) and Structured Query Language (SQL—the standard language for interacting with relational databases) as supported by MySQL, the most popular free database engine available today. Most importantly, you’ll come away with everything you need to start on your very own database driven site!

What’s in this Series?
This series comprises the following 4 chapters. Read them in order from beginning to end to gain a complete understanding of the subject, or skip around if you need a refresher on a particular topic."

It shows how to solve many of the problems that the team will face when documenting,  writing, and testing database code in a team environment, including all the areas such as:

    * Documenting code.
    * Writing readable code.
    * Source control and change management.
    * Deploying code between environments.
    * Unit testing.
    * Reusing code.
    * Searching and refactoring your code base.
