Sequential pattern mining is to discover sequential patterns, with user-specified minimum support of pattern where support is number of sequences that contains pattern, from a database of sequences. Each sequence of database consists of list of transactions ordered by transaction time and each transaction is a set of items. Closed sequential pattern mining has same capability as sequential pattern mining, but in closed sequential pattern mining redundant patterns to be generated and stored are reduced which is much economical.
