The SQL developer needs to be able to create processes for the working database by using one of the many programming objects (like functions, stored procedures, constrains, or triggers). By creating objects that talk with SQL you simply the way other programs (like applications or web pages) can interconnect. These eternal programs only need to call on the names of your programming objects by name rather than needing to submit large pieces of advance code. With SQL Queries 2012 Joes 2 Pros(R) Volume 4, you learn how programming objects work in SQL Server. For those of you who have read the 2008 series for the 70-433 Exam you will find a lot of the same material from the SQL 2008 book in this SQL 2012 book. This is because much of the 70-461 test covers the same material as the 70-433. I have added material that is new to the test and removed material that is no longer relevant. If you have already read this series or have already passed the 70-433 exam you may choose to read my book which covers only the changes from 70-433 to 70-461 entitled "Joes 2 Pros SQL 2012 Queries 70-461 Exam for SQL 2008 Pros.
