Another way this information is used is in categorizing and searching images, such as with Photoshop s file browser To add copyright information to a file, first choose File | File Info You will then see a File Info dialog box similar to the one shown in Figure 1-7, wherein you can choose from the Section drop-down list to enter the following types of information: General Lets you enter information such as the title, author, caption, copyright status, and owner URL

In general, bitmap indexes should be used if The cardinality (the number of distinct values) in the column is low, and The number of rows in the table is high, and The column is used in Boolean algebra operations TIP If you knew in advance what the queries would be, then you could build B*Tree indexes that would work, such as a composite index on SHOP and CHANNEL But usually you don t know, which is where the dynamic merging of bitmaps gives great flexibility

.

There are six commonly used options that can be applied when creating indexes: Unique or nonunique Reverse key Compressed Composite Function based Ascending or descending All these six variations apply to B*Tree indexes, but only the last three can be applied to bitmap indexes A unique index will not permit duplicate values Nonunique is the default The unique attribute of the index operates independently of a unique or primary key constraint: the presence of a unique index will not permit insertion of a duplicate value even if there is no such constraint defined A unique or primary key constraint can use a nonunique index; it will just happen to have no duplicate values This is in fact a requirement for a constraint that is deferrable, as there may be a period (before transactions are committed) when duplicate values do exist Constraints are discussed in the next section A reverse key index is built on a version of the key column with its bytes reversed: rather than indexing John , it will index nhoJ When a SELECT is done, Oracle will automatically reverse the value of the search string This is a powerful technique for avoiding contention in multiuser systems For instance, if many users are concurrently inserting rows with primary keys based on a sequentially increasing number, all their index inserts will concentrate on the high end of the index By reversing the keys, the consecutive index key inserts will tend to be spread over the whole range of the index Even though John and Jules are close together, nhoJ and seluJ will be quite widely separated A compressed index stores repeated key values only once The default is not to compress, meaning that if a key value is not unique, it will be stored once for each occurrence, each having a single rowid pointer A compressed index will store the key once, followed by a string of all the matching rowids.

Categories Lets you place the image in primary and supplemental categories for categorizing and searching Origin Lets you specify the history of the image, and gives you a place to credit a source and specify an editorial urgency The EXIF option doesn t permit you to add information, but does display certain details about the image, such as the resolution, creation software, and compression type

A composite index is built on the concatenation of two or more columns There are no restrictions on mixing datatypes If a search string does not include all the columns, the index can still be used but if it does not include the leftmost column, Oracle will have to use a skip-scanning method that is much less efficient than if the leftmost column is included A function-based index is built on the result of a function applied to one or more columns, such as upper(last_name) or to_char(startdate, 'ccyy-mm-dd') A query will have to apply the same function to the search string, or Oracle may not be able to use the index By default, an index is ascending, meaning that the keys are sorted in order of lowest value to highest A descending index reverses this In fact, the difference is often not important: the entries in an index are stored as a doubly linked list, so it is possible to navigate up or down with equal celerity, but this will affect the order in which rows are returned if they are retrieved with an index full scan
