Riassunto

Beginning with an explanation of the certification process and working through fundamental exam objectives, this guide gives test-takers all they need to know to pass IBM's DB2 10.1 Fundamentals certification exam (Exam 610). All the subjects covered on the exam are included: planning, security, data concurrency, working with databases and database objects, working with data using SQL and XQuery, working with DB2 tables, views, and indexes&;and more. The book concludes with an extensive set of 150 practice questions that mirror the questions found on the exam and detailed answers that explain why the chosen answer is correct and why the others are wrong. Written by a DB2 authority who has helped IBM develop 21 DB2 certification exams, this is the ultimate resource for those who plan to earn their IBM Certified Database Associate certification.

CHAPTER 1

IBM DB2 Certification

Certification has long been a popular trend in the Information Technology (IT) industry. Consequently, many hardware and software vendors — including IBM — have certification programs in place that are designed to evaluate and validate an individual's proficiency with their product offerings.

Recognized throughout the world, the IBM Professional Certification Program offers a wide variety of certification options for IT professionals who want to demonstrate their knowledge and expertise with a particular IBM product. And if you regularly use IBM hardware, software, or both, chances are you have heard of this program and have thought about becoming IBM certified. But, are you aware that IBM has more than 275 different certification roles to choose from? More important, do you know which certification role is right for you? (And, do you know how to prepare for and take the certification exams that are required for the certification role you wish to pursue?)

This chapter is designed to provide you with answers to these and other questions. It begins by introducing you to the certification roles that have been defined for individuals who use IBM's DB2 Information Management software. Then, it shows you how to prepare for the DB2 certification exams, and it concludes with a discussion on how to navigate the testing software that IBM uses to administer most of its exams.

DB2 10 and 10.1 Certification Roles

The IBM Professional Certification Program consists of several distinct certification roles that are designed to guide you in your professional development. To obtain a particular certification, you simply select the role you wish to pursue (based on your knowledge and experience working with a particular IBM product), familiarize yourself with the requirements that have been defined for that role, and then take the required certification exam(s) for the role you have chosen. This book focuses on the IBM Certified Database Associate — DB2 10.1 Fundamentals role (as well as the exam you must take and pass to obtain this certification); however, two DB2 Version 10 and three DB2 Version 10.1 certification roles are currently available:

• IBM Certified Database Associate — DB2 10.1 Fundamentals

• IBM Certified Database Administrator — DB2 10.1 for Linux, UNIX, and Windows

• IBM Certified Database Administrator — DB2 10 for z/OS

• IBM Certified System Administrator — DB2 10 for z/OS
