描述.Expert Indexing in Oracle Database 11g. is about the one database structure at the heart of almost all performance concerns: the index. Database system performance is one of the top concerns in information technology today. Administrators struggle to keep up with the explosion of access and activity driven by the proliferation of computing into everything from phones to tablets to PCs in our increasingly connected world. At the heart of any good-performing database lies a sound indexing strategy that makes appropriate use of indexing, and especially of the vendor-specific indexing features on offer. .Few databases fully exploit the wealth of data access mechanisms provided by Oracle. .Expert Indexing in Oracle Database 11g. helps by bringing together information indexing and how to use it into one, convenient and blissfully short volume that you can read quickly and have at your fingertips for reference. Learn the different types of indices available and when each is best applied. Recognize when queries aren’t using indices as you intend. Manage your indexing for maximum performance. Let .Expert Indexing in Oracle Database 11g. be your guide to deep mastery of the most fundamental

Partitioned Indexes,common, but not essential. It is possible to have partitioned tables without partitioned indexes, and it is possible to have a non-partitioned table with partitioned indexes. There are several factors that affect the design of the database tables and indexes, including:

SpringerBriefs in Molecular Sciencepage numbers in the book. If the topic only appears on a few pages within the book, then the number of pages to read is minimal. In this manner, the usefulness of the index decreases with an increase in the number of times a topic appears in a book.

Optical Studies of ZnXTe(X=Mn,Hg) Alloysdex is an index that’s not automatically available to the cost-based optimizer, unless you make it available by setting a specific initialization parameter. You use invisible indexes mainly for testing the use of an index and to make sure an index is redundant before you drop it.

Yao Ouyang,Xianzhong Yi,Lingxiao Tang the optimizer might prefer a full table scan to using an index. You’ll also learn how to force the optimizer to use (or not to use) an index. Oracle provides a large number of index-related hints to enable you to control the behavior of the optimizer regarding index usage. You’ll find descriptions of the key index-related hints in this chapter.
