RRN Meaning and
Definition
-
RRN stands for "Relative Record Number." It is a term commonly used in the field of computer science and database management.
In the context of databases, RRN refers to a unique identifier that signifies the position or index of a particular record within a file or database table. The RRN is typically an integer value and is assigned sequentially to each record as it is added to the file or table. This number serves as a means to access or locate the desired record efficiently, especially in situations where the record's key value is not known or is not unique.
The RRN allows for direct retrieval of a record based on its relative position, regardless of the order in which records were added or their key values. It is often used in conjunction with other indexing methods to improve data retrieval performance in large databases.
RRN also plays a crucial role in the implementation of sequential file organization, where records are stored physically by their insertion order or some specific order defined by the programmer. The RRN aids in maintaining the logical ordering of records, thereby facilitating sequential file processing operations such as application of sorting algorithms or navigation through the records.
In summary, RRN is a unique numerical identifier assigned to each record in a file or database table, allowing for efficient retrieval and navigation of records based on their relative position or order.
