You know the rudiments of the SQL query language, yet you feel you aren't taking full advantage of SQL's expressive power. You'd like to learn how to do more work with SQL inside the database before pushing data across the network to your applications. You'd like to take your SQL skills to the next level.Let's face it, SQL is a deceptively simple language to learn, and many database developers never go far beyond the simple statement: SELECT columns FROM table WHERE conditions. But there is so much more you can do with the language. In the SQL Cookbook, experienced SQL developer Anthony Molinaro shares his favorite SQL techniques and features. You'll learn about:Window functions, arguably the most significant enhancement to SQL in the past decade. If you're not using these, you're missing outPowerful, database-specific features such as SQL Server's PIVOT and UNPIVOT operators, Oracle's MODEL clause, and PostgreSQL's very useful GENERATE_SERIES functionPivoting rows into columns, reverse-pivoting columns into rows, using pivoting to facilitate inter-row calculations, and double-pivoting a result setBucketization, and why you should never use that term in Brooklyn.How to create histograms, summarize data into buckets, perform aggregations over a moving range of values, generate running-totals and subtotals, and other advanced, data warehousing techniquesThe technique of walking a string, which allows you to use SQL to parse through the characters, words, or delimited elements of a stringWritten in O'Reilly's popular Problem/Solution/Discussion style, the SQL Cookbook is sure to please. Anthony's credo is: "When it comes down to it, we all go to work, we all have bills to pay, and we all want to go home at a reasonable time and enjoy what's still available of our days." The SQL Cookbook moves quickly from problem to solution, saving you time each step of the way.

This book is an anthology of effective database management techniques representing the collective wisdom of the OakTable Network. With an emphasis upon performance―but also branching into security, national language, and other issues―the book helps you deliver the most value for your company’s investment in Oracle Database technologies. You’ll learn to effectively plan for and monitor performance, to troubleshoot systematically when things go wrong, and to manage your database rather than letting it manage you.

Oracle database administration requires a vast amount of information and an ability to perform a myriad of tasks--from installation to tuning to network troubleshooting to overall daily administration. Oracle provides many tools for performing these tasks; the trick is knowing what tool is right for the job, what commands you need to issue (and when), and what parameters and privileges you need to set. And, as every DBA knows, you need to know how do all this under pressure, while you face crisis after crisis.This book provides a concise reference to the enormous store of information an Oracle DBA needs every day (as well as what's needed only when disaster strikes). It's crammed full of quick-reference tables, task lists, and other summary material that both novice and expert DBAs will use time and time again. It covers the commands and operations new to Oracle8, but also provides Oracle7 information for sites still running earlier versions.Oracle Database Administration provides two types of material:DBA tasks--chapters summarizing how to perform critical DBA functions: installation, performance tuning, preventing data loss, networking, security and monitoring, auditing, query optimization, and the use of various Oracle tools and utilitiesDBA reference--chapters providing a quick reference to the Oracle instance and database, the initialization (INIT.ORA) parameters, the SQL statements commonly used by DBAs, the data dictionary tables, the system privileges and roles, and the SQLPlus, Export, Import, and SQLLoader syntaxThe book also includes a resource summary with references to additional books, Web sites, and other online and offline resources of special use to Oracle DBAs.Oracle Database Administration is the single essential reference you'll turn to again and again. If you must choose only one book to use at the office, keep at home, or carry to a site you're troubleshooting, this will be that book.

As a society that relies on technology to thrive, we face a growing number of potentially catastrophic threats to network security daily. DATABASE SECURITY delivers the know-how and skills IT Professionals must have to protect technology infrastructures, intellectual property, and the company's prosperity. From database installation and testing to auditing and SQL Injection, DATABASE this text delves into the essential processes and protocols that prevent intrusions, while reinforcing each topic with eye-opening, real-world examples. Unlike most texts on database security, which take a computer scientist's analytical approach, Database Security focuses on implementation, and was written expressly for the expanding field of Information Technology careers.

Looks at the storage of networks of objects and procedures in a database and describes the development of object-oriented databases

Database Aesthetics examines the database as cultural and aesthetic form, explaining how artists have participated in network culture by creating data art. The essays in this collection look at how an aesthetic emerges when artists use the vast amounts of available information as their medium. Here, the ways information is ordered and organized become artistic choices, and artists have an essential role in influencing and critiquing the digitization of daily life.

The experience of networks as the immediate sensing of relations between humans and nonhuman technical elements in assemblages such as viral media and databases.Today almost every aspect of life for which data exists can be rendered as a network. Financial data, social networks, biological ecologies: all are visualized in links and nodes, lines connecting dots. A network visualization of a corporate infrastructure could look remarkably similar to that of a terrorist organization. In An Aesthesia of Networks, Anna Munster argues that this uniformity has flattened our experience of networks as active and relational processes and assemblages. She counters the “network anaesthesia” that results from this pervasive mimesis by reinserting the question of experience, or aesthesia, into networked culture and aesthetics.Rather than asking how humans experience computers and networks, Munster asks how networks experience―what operations they perform and undergo to change and produce new forms of experience. Drawing on William James's radical empiricism, she asserts that networked experience is assembled first and foremost through relations, which make up its most immediately sensed and perceived aspect. Munster critically considers a range of contemporary artistic and cultural practices that engage with network technologies and techniques, including databases and data mining, the domination of search in online activity, and the proliferation of viral media through YouTube. These practices―from artists who “undermine” data to musicians and VJs who use intranetworked audio and video software environments―are concerned with the relationality at the core of today's network experience.
