The algorithm used by the ORACLE Server to locate data within a database. When the optimizer parses a SQL statement it evaluates possible access paths in order to use the best access path. To some degree, users can help the optimizer choose an access path through deliberate wording of SQL statements.
The logical route an end user takes to access computerized information. Typically, it includes a route through the operating system, telecommunications software, selected application software and the access control system.
The complete route, including the drive letter, directory, and all sub-directories, that directs an operating system to a file or application in a storage device. For example, the access path C:\WlNDOWS\SYSTEM\crmscip indicates that the crmscip file is stored in the SYSTEM sub-directory in the WINDOWS directory, which is on the C: drive. Also called directory path.
