If more than one index is present the other ones are called alternate indexes.The COBOL language supports indexed files with the following command in the FILE CONTROL section. however a sequential file isA file that contains records or other elements that are stored in a chronological order based on account number or some other identifying data. In order to locate the desired data, sequential files must be read starting at the beginning of the file. A sequential file may be stored on a sequential access device such as magnetic tape or on a direct access device such as magnetic disk. Contrast with random-file.Read more: sequential-fileContent of sequential file can't be accessed directly while index file content can be accessed directly through pointer.

Difference between primary index and secondary index?
Index files are auxiliary file stored in database used in faster accessing of data , and it is important especially when database file size growing exponentially. Today world storage is not a problem, but retrieval/searching on certain criteria is problem.Index files- Secondary or auxiliary files that help speed up access in primary filesIndexes or access structure: data structure -- data structure used for fast access.Primary index: An index structure that is defined on the ordering field (that is used to physically order records on disk in sorted file organization)Secondary index : used to index field that are neither ordering fields nor key fields(there is no assurance that the file is organized on key field or primary key field). One index entry for every tuple in the data file(dense index) contain the value of the indexed attribute and pointer to the block /recordWhat happens when Key field is used as index filed in Secondary Index?Since the key fields are unique , number of index entries equal to number of recordsData records need not be sorted on diskFixed length records for index fileWhat happens when non-Key field is used as index filed in Secondary Index?When a non key filed is indexed, indexed field entry need not be unique, there can be duplicate entry.How to handles these duplicate entry?There methods are there to handle this duplicate valueDuplicate index entriesVariable length records (one value should point more than one records)Extra redirection levels

In a complete binary tree (CBT) stored using an array, the parent of an element at index i can be found at index (i-1)/2, assuming the array is 0-indexed. So for an element stored at index 11, the parent node would be stored at index (11-1)/2 = 5.
