The topics include: An Oracle database is a collection of data treated as a unit. The purpose of a database is to store and retrieve related information. A database server is the key to solving the problems of information management. In general, a server reliably manages a large amount of data in a multiuser environment so that many users can concurrently access the same data. All this is accomplished while delivering high performance. A database server also prevents unauthorized access and provides efficient solutions for failure recovery. The database has logical structures and physical structures. Because the physical and logical structures are separate, the physical storage of data can be managed without affecting the access to logical storage structures. Logical Database Structures. The logical structures of an Oracle database include schema objects, data blocks, extents, segments, and tablespaces. Schemas and Schema Objects. A schema is a collection of database objects. A schema is owned by a database user and has the same name as that user. Schema objects are the logical structures that directly refer to the database's data. Schema objects include structures like tables, views, and indexes. There is no relationship between a tablespace and a schema. Objects in the same schema can be in different tablespaces, and a tablespace can hold objects from different schemas.)Some of the most common schema objects are defined in the following section. See Also: Chapter 1. Schema Objects" for detailed information on these schema objects, and for information on other schema objects, such as dimensions, the sequence generator, synonyms, index- organized tables, domain indexes, clusters, and hash clusters. Tables. Tables are the basic unit of data storage in an Oracle database. Database tables hold all user- accessible data. Each table has columns and rows. Oracle stores each row of a database table containing data for less than 2. A table that has an employee database, for example, can have a column called employee number, and each row in that column is an employee's number. Views. Views are customized presentations of data in one or more tables or other views. A view can also be considered a stored query. Views do not actually contain data. Rather, they derive their data from the tables on which they are based, referred to as the base tables of the views. Like tables, views can be queried, updated, inserted into, and deleted from, with some restrictions. All operations performed on a view actually affect the base tables of the view. Views provide an additional level of table security by restricting access to a predetermined set of rows and columns of a table. They also hide data complexity and store complex queries. Indexes. Indexes are optional structures associated with tables. Indexes can be created to increase the performance of data retrieval. Just as the index in this manual helps you quickly locate specific information, an Oracle index provides an access path to table data. When processing a request, Oracle can use some or all of the available indexes to locate the requested rows efficiently. Indexes are useful when applications frequently query a table for a range of rows (for example, all employees with a salary greater than 1. Indexes are created on one or more columns of a table. After it is created, an index is automatically maintained and used by Oracle. Changes to table data (such as adding new rows, updating rows, or deleting rows) are automatically incorporated into all relevant indexes with complete transparency to the users. You can partition indexes. Clusters. Clusters are groups of one or more tables physically stored together because they share common columns and are often used together. Because related rows are physically stored together, disk access time improves. Like indexes, clusters do not affect application design. Whether or not a table is part of a cluster is transparent to users and to applications. Data stored in a clustered table is accessed by SQL in the same way as data stored in a nonclustered table. Data Blocks, Extents, and Segments. The logical storage structures, including data blocks, extents, and segments, enable Oracle to have fine- grained control of disk space use. Oracle Data Blocks. At the finest level of granularity, Oracle database data is stored in data blocks. One data block corresponds to a specific number of bytes of physical database space on disk. The standard block size is specified by the initialization parameter DB_BLOCK_SIZE. In addition, you can specify of up to five other block sizes. A database uses and allocates free database space in Oracle data blocks. See Also: "Multiple Block Sizes"Extents. The next level of logical database space is an extent. An extent is a specific number of contiguous data blocks, obtained in a single allocation, used to store a specific type of information. Segments. Above extents, the level of logical database storage is a segment. A segment is a set of extents allocated for a certain logical structure. The following table describes the different types of segments. Segment. Description. Data segment. Each nonclustered table has a data segment. All table data is stored in the extents of the data segment. For a partitioned table, each partition has a data segment. Each cluster has a data segment. The data of every table in the cluster is stored in the cluster's data segment. Index segment. Each index has an index segment that stores all of its data. For a partitioned index, each partition has an index segment. Temporary segment. Temporary segments are created by Oracle when a SQL statement needs a temporary work area to complete execution. When the statement finishes execution, the extents in the temporary segment are returned to the system for future use. Rollback segment. If you are operating in automatic undo management mode, then the database server manages undo space using tablespaces. Oracle Corporation recommends that you use "Automatic Undo Management" management. However, if you are operating in manual undo management mode, then one or more rollback segments for a database are created by the database administrator to temporarily store undo information. The information in a rollback segment is used during database recovery: To generate read- consistent database information. Oracle dynamically allocates space when the existing extents of a segment become full. In other words, when the extents of a segment are full, Oracle allocates another extent for that segment. Because extents are allocated as needed, the extents of a segment may or may not be contiguous on disk. See Also: "Automatic Undo Management""Read Consistency""Database Backup and Recovery Overview"Tablespaces. A database is divided into logical storage units called tablespaces, which group related logical structures together. For example, tablespaces commonly group together all application objects to simplify some administrative operations. Databases, Tablespaces, and Datafiles. The relationship between databases, tablespaces, and datafiles (datafiles are described in the next section) is illustrated in Figure 1- 1. Figure 1- 1 Databases, Tablespaces, and Datafiles. Text description of the illustration cncpt. This figure illustrates the following: Each database is logically divided into one or more tablespaces. One or more datafiles are explicitly created for each tablespace to physically store the data of all logical structures in a tablespace. The combined size of the datafiles in a tablespace is the total storage capacity of the tablespace. The SYSTEM tablespace has 2 megabit (Mb) storage capacity, and USERS tablespace has 4 Mb). The combined storage capacity of a database's tablespaces is the total storage capacity of the database (6 Mb). Online and Offline Tablespaces. A tablespace can be online (accessible) or offline (not accessible). A tablespace is generally online, so that users can access the information in the tablespace. However, sometimes a tablespace is taken offline to make a portion of the database unavailable while allowing normal access to the remainder of the database. This makes many administrative tasks easier to perform. Physical Database Structures. The following sections explain the physical database structures of an Oracle database, including datafiles, redo log files, and control files. Datafiles. Every Oracle database has one or more physical datafiles. How to install checkpoint gaia on vmware.
