Bitmap join indexes: These provide a means of denormalizing data in an index structure, instead of in a table For example, consider the simple EMP and DEPT tables Someone might ask the question, How many people work in departments located in the city of Boston EMP has a foreign key to DEPT, and in order to count the employees in departments with a LOC value of Boston, we would normally have to join the tables to get the LOC column joined to the EMP records to answer this question Using a bitmap join index, we can instead index the LOC column against the EMP table The same caveat in regard to OLTP systems applies to a bitmap join index as a regular bitmap index Function-based indexes: These are B*Tree or bitmap indexes that store the computed result of a function on a row s column(s), not the column data itself.

You can consider them an index on a virtual (or derived) column in other words, a column that is not physically stored in the table These may be used to speed up queries of the form SELECT * FROM T WHERE FUNCTION(DATABASE_COLUMN) = SOME_VALUE, since the value FUNCTION(DATABASE_COLUMN) has already been computed and stored in the index Application domain indexes: These are indexes you build and store yourself, either in Oracle or perhaps even outside of Oracle You tell the optimizer how selective your index is and how costly it is to execute, and the optimizer will decide whether or not to use your index based on that information The Oracle text index is an example of an application domain index; it is built using the same tools you may use to build your own index.

Note For those of you familiar with older versions of SQLite, these result codes are part of the more advanced and some would say more correct set of result codes that replace the legacy simple return values like SQLITE_ERROR. A full list of result codes and extended result codes is available at www.sqlite.org/c3ref/

It should be noted that the index created here need not use a traditional index structure The Oracle text index, for example, uses a set of tables to implement its concept of an index..

Also, protection can t be changed in a shared workbook, so you can t run macros that unprotect the worksheet, make changes, and then reprotect the worksheet. Will Users Enable Macros in Your Workbook If your pivot table requires macros for some functionality, will users have the ability to enable macros In some environments, they may not be able to use macros. Will that have a serious impact on the value of your pivot table

As you can see, there are many index types to choose from. In the following sections, I ll present some technical details on how each one works and when it should be used. I would like to stress again that we will not cover certain DBA-related topics. For example, we will not discuss the mechanics of an online rebuild; rather, we will concentrate on practical application-related details.

B*Tree or what I call conventional indexes are the most commonly used type of indexing structure in the database. They are similar in implementation to a binary search tree. Their goal is to minimize the amount of time Oracle spends searching for data. Loosely speaking, if you have an index on a number column, then the structure might conceptually look like Figure 11-1.

All other API functions related to data access use the statement s cursor to obtain information about the current record. For example, the sqlite3_column_xxx() functions all use the statement handle, specifically its cursor, to fetch the current record s fields.

Note There are block-level optimizations and compression of data that take place that make the real block

The sales manager sent you an Excel workbook that contains last year s sales orders, and wants you to create a pivot table to summarize the data. You had problems with the last pivot table you created and couldn t get the totals you wanted. To avoid similar problems this time, before creating the pivot table, you want to ensure the data is set up correctly. This problem is based on the sample file named ProductSales.xlsx.

structure look different from Figure 11-1.
