By default, in an ascending-order sort, the NULL values appear at the bottom of the result set; that is, NULL s are sorted higher. For descending-order sorts, NULL values appear at the t[r]

It can be difficult to write books about new features. First, you don’t start out running the production product. You write using a beta copy of the software, and just hope tha[r]

When you install Oracle software, you can choose the Basic Installation option and select the Create Starter Database check box. This database will have the sample schemas used in this book. The password you specify will be applicable to the SYS[r]

You’ll learn about tables and sequences, which generate a series of numbers, and indexes, which act like an index in a book and allow you quick access to rows. You’ll also learn about views, which are predefined queries on one or more tables; among other benefits, views allow you to[r]

probably USER as well. You can adjust the defaults for sizing the tablespaces and add new tablespaces, for an application or for a schema. Having different tablespaces helps to organize the objects in the database. This organization used to be mainly by tables and indexes, but[r]

The flashback data archive feature overcomes these limitations of current techniques to maintain historical data. Using this feature, you can have the database automatically track all changes to a specified table or a set of tables and store and maintain an archive of historic[r]

Scalability and performance improvements are largely based on Oracle’s grid computing model. Grid computing is intended to allow businesses to move away from the idea of many individual servers, each of which is dedicated to a small number of applications. When config[r]

Performance
Most customers’ second question after, “How does TDE work?” is, “What effect will this have on the performance of my database systems?” These are both certainly fair questions. Everyone is trying to maximize their resources, get the most out of their hardware, and keep a[r]

If you are working continuously with a similar set of SQL statements (like INSERT
