A database is a collection of data organized in a manner that facilitates updation, retrieval and management of the data. Searching an unindexed database having n keys will have a worst case running time of O (n). If the similar data is indexed along with a b-tree, then the similar search operation will run in O(log n) time. Indexing great amounts of data can improve search performance significantly.
Data records are stored in some particular sequence e.g., order of arrival value of key field etc. Records of sequential file cannot be randomly accessed i.e., to access the n th
